  1. Roof Spraying

    Leave a Comment

    What Is Roof Spraying?

    Roof spraying is the process of applying a protective roof treatment to roof tiles, in order provide the roof with added protection against weathering, while also adding a new and attractive look to the roof. 

    Why Spray A Roof?

    Contrary to popular belief, mineral building materials such as roof tiles are porous, meaning they absorb moisture. The more porous a surface, the moisture can enter the material.

    Moisture is the single biggest cause of building material deterioration. In the case of roof tiles, when temperatures drop below freezing, any moisture that is present within the tiles will undergo a freeze-thaw cycle. This freeze-thaw cycle causes the moisture expand as it turns to a solid, causing cracks in the roof tile to open up under the movement. These cracks further compromise the ability for the roof tile to keep water out, leading to further damage.

    Moisture can also create the ideal environment for moss, lichens & other green growth to develop on & in-between roof tiles, which is a common sight for many homeowners across the UK.

    While moss can be an aesthetic problems for properties, there are more damaging problems caused by moss that are less visible. By growing in the gaps between roof tiles, moss can compromise the ability for your roof to keep out moisture. If moss is allowed to grow on your roof long-term, the rainwater that the moss will absorb can cause roof tiles to rot due to the consistent exposure to high levels of moisture. Furthermore, the growth of the moss will fill the gaps between the roof tiles, which can move & damage the roof tiles

    This is where spraying a roof comes in. By applying a protective coating to the roof tiles, you help to ensure that moisture cannot absorb into the roof tiles. This adds additional weather protection to the roof tiles, helping to extend their lifespan and preventing the need for a roof replacement, which can often be unnecessary.

    What Products Do You Spray?

    When it comes to spraying roofs, there are two options. You can either apply a clear treatment or a coloured paint.

    Here at ProPERLA UK we have developed the most advanced exterior coatings in the UK that contain our super hydrophobic nano-technology. This technology creates a water repellent surface on the roof tiles that prevents up to 96.3% of water absorption. This is caused when water droplets are unable to stick to the treated roof tile, causing it to simply form beads on the surface. 

    While preventing water absorption, the technology remains highly breathable. Breathability refers to the ability for water vapour to travel through a surface. If surface is not breathable, any moisture from inside the material will become trapped as it cannot freely breathe out. Over time, this build up of moisture will cause significant damage to the material and any coating applied to it will fail.

    By preventing water absorption while remaining highly breathable, the roof tiles treated with super hydrophobic stay dry, helping to prevent damage and keeping them looking clean by preventing moss growth.

    Our clear ProPERLA Water Repellent is a completely invisible waterproof treatment for roof tiles that penetrates deep into the roof tile. This maintains the natural beauty of the roof tile, while still providing waterproof protection.

    Our RENOTEC Roof Coating is a coloured roof coating that can completely transform a roof. As a paint, it works on the surface of the roof tile, however unlike 'sealers' that form a non-breathable film on the surface of roof tiles, the roof coating lines the pores of the tile without sealing these pores. This maintains breathability and provides a long-lasting, attractive finish.

    Both products have undergone independent testing by UKAS accredited laboratory Lucideon, which found that after 25 years accelerated weathering, both treatments showed no signs of deterioration in appearance or performance. This makes ProPERLA Water Repellent & RENOTEC Roof Coating the most durable and advanced roof treatments available in the UK today.

    How Are Roof Sprayed?

    Step 1: Cleaning

    The first step of applying any protective paint or coating is to ensure the surface is clean. Removing any moss, green growth and other containments is crucial for achieving long-lasting results. 

    Modern methods of cleaning do not damage roof tiles, which is what has occurred over the years with strong pressure washing of roofs before treating.

    When the large containments are removed, a fungicidal cleaner is applied to the roof to prevent any fungal growth from growing on the roof once treated. If fungal growth is left untreated, there is a risk it could continue to bloom on the roof tiles.

    Once the roof is clean, it is left to completely dry before spraying.

    Roof Cleaning

    Step 2: Spraying

    Once cleaned, the roof treatments are then applied. RENOTEC Roof Coating as a coloured paint is applied using a spray machine such as an airless spray machine or a HVLP. This is used in order to achieve a perfectly smooth, uniform finish across the roof.

    ProPERLA Water Repellent as a clear treatment does not have to be applied using a spray machine. This is because it is an impregnating system that penetrates into the roof tiles. This means that it does not need to be applied to achieve a neat finish and simply needs to be applied evenly. For this reason, a hand-pump sprayer can be used to apply the treatment.

    ProPERLA products contain a specialist technology that must be applied by experts in order to ensure they perform to their maximum performance of over 25 years. Furthermore, due to the safety requirements of treating and cleaning a roof, it is recommended that you seek the help of an expert.

    We have a number of approved ProPERLA applicators up and down the UK who have attended our rigorous training program to ensure they apply our products to the highest level. To find an approved ProPERLA applicator, simply type your postcode in our applicator finder tool and find your nearest applicator, who can paint your roof & protect it for decades to come.

    Q. What is the water absorption difference between a non treated roof tile & a treated one?

    As roof tiles are applied to roofs to keep the weather out, we assume that they are completely waterproof. The reality is, they are porous and will uptake moisture. In the image below you can see a roof tile that has half treated with ProPERLA and half left untreated. With the treated side you can see how the surface repels the water, while the water has soaked through into the roof tile on the untreated side.

  2. Can You Paint Roof Tiles?

    Leave a Comment

    A question we get asked a lot here at ProPERLA is whether you can paint roof tiles or not? In this guide we are going to answer all of the most common questions regarding painting roof tiles so you can find all the information you need in one place.

    Can You Paint Roof Tiles?

    Let's start with the question of whether you can paint roof tiles or not, as there is a lot of misinformation regarding this in the UK. 

    The answer is simple, yes, you can paint roof tiles. Roof tiles of all types, from concrete to clay, can be painted using a specialist product called a roof coating. A roof coating is a specially designed treatment that adheres to the natural mineral surface of the roof tile, offering a beautiful new look to the roof.

    Why Paint Roof Tiles?

    You may be wondering, why is painting roof tiles not more common? The reality is, roof coatings are experiencing a huge resurgence in the last few years thanks to more advanced technologies being developed. Roof coatings were previously generally poor quality, meaning they could fail in a matter of years. This, along with unreputable companies selling roof coatings as energy efficient meant that painting roof tiles was something that homeowners were cautious to do.

    Roof coatings cannot improve the energy efficiency of a property by insulating the roof tiles, This is because roof tiles do not transfer significant amounts of heat from a property when wet. If you want to improve the energy efficiency of your roof, loft insulation is the best option.

    This is not to be confused with exterior walls that have been shown to be improved in energy efficiency when coated using a waterproof exterior wall coating. This is because exterior walls have been shown to transfer significant amounts of heat, leading to energy loss as a result. Over 35% of heat loss occurs through the wall of a property, and just 5% damp content within a wall can lower its insulation by 50%. By keeping exterior walls dry, you can improve their thermal efficiency significantly. 

    So if roof coatings cannot improve thermal efficiency of a property, what benefits do they have? Painting roof tiles can:

    1. Improve the performance of the roof tiles by providing them with a new attractive colour

    2. Extend the life span of the roof tiles by preventing the loss of structural strength in roof tiles through weathering, frost damage and salt efflorescence, plus by obstructing the growth of unsightly moss, algae and lichens

    Renotec

    1. Improved Appearance

    Roof tiles over time can become weathered, after all, they have to withstand a large amount of wind & rain, especially here in the UK. This weathering over time can have an impact of the roof, causing roof tiles to look patchy, discoloured and covered in moss.

    Painting roof tiles provides the roof with a uniform finish in a colour of your choice. The impact this can have on the appearance of a property cannot be understated, as it can instantly give any property a clean, crisp look.

    2. Protection

    Contrary to popular belief, mineral building materials such as brick, concrete, stone, timber & roof tiles are all porous, meaning they absorb moisture. The more porous a surface, the more liquid or gas can pass through voids & be held in the material.

    Moisture is the single biggest cause of building material deterioration. When temperatures go below freezing, any moisture that is present within building material such as roof tiles will undergo a freeze-thaw cycle. This freeze-thaw cycle causes the moisture to go from a liquid into a solid, causing it to expand. This expansion can cause cracks in the roof tile to open up, allowing more moisture to enter and then causing the cycle of deterioration to continue. 

    Moisture can also create the ideal environment for moss, lichens & other green growth to develop on & in-between roof tiles. Moss does not just impact the appearance of the roof, by growing in the gaps between roof tiles, moss can compromise the ability for your roof to keep out moisture. If moss is allowed to grow on your roof, the moisture that the moss soaks up can cause roof tiles to rot due to the consistent exposure to moisture. Furthermore, the growth of the moss will fill the gaps between the roof tiles, which can move & damage the roof tiles. This is because the moss soaks up water & expands, which can compromise the bond between the adjoining materials that ensure the integrity of the roof. Eventually, roof tiles can crack under the movement & will need repairing as a result.

    A roof coating is designed to help protect the roof tiles from this damage by improving its ability to keep this moisture out. Advanced roof coatings contain super hydrophobic technology that creates a water repellent surface on roof tiles. This water repellent surface prevents any moisture from entering the roof tiles, which not only helps protect it from weathering but also discourages the growth of moss that relies on this moisture to grow.

    By protecting roof tiles, you can expand their lifespan, providing an alternative to the often costly and unnecessary roof replacement that some homeowners opt for. 

    RENOTEC

    Breathability

    Not all roof paints or coatings should be used on a roof. As we have mentioned previously, poor quality roof coatings have often led to highly advanced roof paints being tarnished with the same brush.

    Any product that is applied to an exterior surface, be it a wall, roof or timber, should be breathable. Breathability refers to the ability for water vapour to travel through a surface. If a paint or coating is not breathable, any moisture from inside the material will become trapped. Over time, this build up of moisture will cause the paint to fail, once it has caused significant damage to the building material.

    This low breathability is generally found in waterproofing treatments that refer to themselves as 'sealers', A sealer will prevent water absorption but will achieve this while completely sealing the surface, causing moisture to become trapped underneath the film of the sealer.

    Certain paints can also have low breathability, so it is crucial that you check before using a product that it will not impact the breathability of your roof.

    Super Hydrophobic Nano-Technology

    To provide a paint for roof tiles that prevents water from entering a material but while also maintaining breathability, we developed super hydrophobic nano-technology here at ProPERLA.

    ProPERLA products create a super hydrophobic surface that repels water, preventing up to 96% of water absorption. This is caused when water droplets are unable to stick to the painted surface, instead simply forming beads on the surface of the materials.

    Roof paint

    Roof tiles painted using RENOTEC Roof Coating

    While preventing water absorption, the products also remain highly breathable, allowing water vapour to naturally pass through the substrate. This maintains the breathability of the material and ensures it stays dry long-term. This is what gives ProPERLA nano-technology its durability. Independent testing was conducted of ProPERLA roof paints & treatments to find out how they would perform in the harshest weathering conditions. They were subject to 25 years accelerated weathering, exposing them to extreme weather conditions from sub-zero temperatures to 70°C. After 25 years weathering, the roof paints were found to have not changed in appearance or performance, suggesting that they would far exceed a 25 year proven performance. This makes our roof paints & treatments the most advanced products currently available in the UK.

    ProPERLA nano-technology also has self-cleaning properties as any dirt on the surface is simply cleaned off with any rainfall, while also discouraging the growth of moss, lichens & green growth. This not only helps to ensure roof tiles do not become damaged, but also ensures that they remains clean and free from moss growth.

    Frequently Asked Questions

    Q. Do you clean roofs before painting them?

    When of the areas that causes some confusion is the cleaning of roofs before applying treatments. Roof tiles must be cleaned like any surface before painting to ensure the paint can properly adhere to the surface. This should be done by not damaging the roof, which is why it is often done using modern steam cleaning techniques that do not impact the integrity of the roof.

  3. Cleaning and Sealing Driveways – What You Need To Know

    Leave a Comment

    In the UK, exterior surfaces have to withstand high levels of weathering almost all year round that can leave them looking a bit tired. One area particularly susceptible to dirt & discolouration is driveways, as they have to undergo a lot of traffic over time which can lead to dirt and debris gathering. In this guide we are going to cover everything you need to know about cleaning and sealing driveways so you can have your driveway looking brand-new again.

    Driveways

    Driveways are most commonly made from blocks such as brick, cement, sandstone & other mineral substrates. Each block or paver is separate, meaning they can be individually placed and removed. 

    The individual nature of each block means they are available in a series of patterns & in a range of colours to create any design, making them versatile enough to be used on both traditional and modern properties. 

    The Problem Driveways

    Any driveway, be it brick, stone or concrete. as a natural mineral substrate will absorb moisture. This is contrary to what many people believe, as we presume they are made to keep out water as an exterior surface. This is because natural mineral surfaces are porous, meaning water can transfer easily through the pores of the material. The more porous the driveway, the more water it can absorb. 

    Moisture is the single biggest cause of building material deterioration. For this reason, this water absorption is something that can cause a lot of problems to your driveway.

    For a start, it can actually crack from the moisture. This is because moisture that absorbs into the material through pores or through hairline cracks can undergo a freeze-thaw cycle. This is the process of water freezing, in turn expanding due to the liquid becoming a solid. That expansion results in cracks in the driveway to open up, allowing more moisture to enter the material and continuing a cycle of deterioration. This is particularly a problem with driveways as it is a horizontal surface, meaning it is even easier for moisture to absorb into the surface than it would be with a vertical surface such as exterior walls.

    Aside from damage to the integrity of the driveway itself, moisture can also create the ideal environment for moss, lichens & other green growth to develop on the face of the driveway. This is the main reason why homeowners may be looking to clean and seal their driveway, as once able to bloom, this natural growth can cause the driveway to lose significant visual appeal.

    As well as natural growth, driveways are very susceptible to dirt as they must endure high levels of traffic, from shoes to cars. This dirt attaches itself to the driveway & becomes ingrained in the natural substrate, making it very difficult to keep the surface clean.

    The Solution

    Simply cleaning the driveway will lead to the same damage, discolouration, dirt & green growth happening again after a matter of months. The regular maintenance cycle of the driveway will continue unless you protect the surface from moisture.

    This is where waterproofing treatments such as sealers come in, which prevent the water absorption of surface by creating a water repellent coating.

    In the UK today there is a lot of conflicting information regarding sealers. The problem with concrete sealers & other sealing products is that while they sealers prevent water absorption, they do this by creating a film on the surface of the driveway or other substrate. The film that they create impacts the breathability of the substrate, as any water vapour that previous could freely pass through the surface becomes trapped. Eventually, the moisture that builds-up causes damage to the substrate and will cause the film of the sealer to break under the pressure. 

    Sealed driveway

    This is why impregnator treatments were developed. These impregnators penetrate into the substrate rather than creating a film on the surface. This means they work below the surface, waterproofing the substrate itself.

    At ProPERLA we developed our super hydrophobic impregnators using the latest nano technology. Designed for driveways, patios & walkways, ProPERLA Paving Impregnator creates a super hydrophobic surface that repels water, preventing 95% of water absorption. This is achieved when water droplets are unable to stick to the treated substrate, instead simply forming beads on the surface of the driveway.

    While preventing water absorption, the impregnator also remains highly breathable, allowing water vapour to freely pass through the treated surface. By chemically bonding to the mineral surface, it lines the pores of paving rather than sealing them,

    Maintenance

    By keeping driveway surfaces dry & ProPERLA not protects paving  long-term, but also improves the appearance of them.

    Once applied to driveways, ProPERLA Paving Impregnator:

    • Deters the unsightly growth of moss, mildew and algae
    • Prevents stains
    • Protects against the damaging effects of rain and frost damage
    • Improves the long term appearance of driveways & patios by creating a self-cleaning surface

    Similarly to water not being able to attach itself to the driveway once it has been treated, dirt also cannot attach to driveways. This means that with any rainfall, dirt will simply wash away. This also helps to prevent the deep, ingrained dirt that can gather on high traffic surfaces such as driveways and other paving. 

    As a more natural form of waterproofing for driveways compared to a sealer. It is important to note that impregnators or sealers are generally clear, meaning they offer invisible treatment. In the case of sealers, as these are film forming, they can sometimes leave a sheen which can either be desired or not. An impregnator as it works below the surface will not form any sheen on the surface, leaving the paving completely natural looking.

    Cleaning Driveways

    Before any treatment is applied, driveways must be completely clean of any dirt, debris and other contaminants. This is usually done using a pressure washer to remove deep ingrained dirt from the natural mineral surface.

    Once all contaminants are removed, it is important to apply a fungicidal treatment to the paving in order to kill any fungal growth. If any moss, green growth or lichens are left on the driveway, this could bloom and prevent the subsequent treatment from performing to the best of its ability.

    Sealing Driveways

    What many people would refer to as sealing a driveway is the process of applying a waterproofing treatment. Whether you opt to use a sealer or an impregnator, it is important to seek the help of professionals as these treatments must be applied correctly to perform.

    ProPERLA Paving Impregnator in particular is a specialist technology that must be applied by experts in order to ensure maximum performance during the block paving restoration process.

    ProPERLA Paving Impregnator is available with a 10 year guarantee, which outperforms many sealers that will last 1-3 years. This guarantee can only be issued by approved applicators who have attended our rigorous training program to ensure they apply the treatments to the highest level. To find an approved ProPERLA applicator, simply type your postcode in our applicator finder tool and find your nearest applicator, who can carry out a full driveway cleaning & sealing for you.

    Frequently Asked Questions

    Q. Will sealing driveways prevent staining?

    Stains from oil & other contaminants is a particular problem for driveways. As well as contaminants, moisture itself can cause staining and discolouration of the paving. By applying an impregnator, you significantly reduce the risk of staining.

    It is much easier to prevent staining than to remove it. That is why sealing driveways should be considered by those that have properties that do not offer from it, just as it should be by those who do. Protecting your exterior surfaces from deterioration as a preventative solution is a great way to invest in your property long-term.

    Q. How do I become an approved applicator of ProPERLA products?

    To ensure our products are only applied by trained experts, we ensure that applicators attend our training course in order to become an approved applicator of ProPERLA products. Why not read more about our training course if you would like to be able to offer ProPERLA technology to your clients?

    Q. How long does ProPERLA Paving Impregnator last?

    Due to the fact that sealers are not breathable, sealers are likely to fail after 1-3 years when moisture becomes trapped underneath the film. By maintaining full breathability & by not forming a film on the surface of driveways, ProPERLA Paving Impregnator comes with a 10 year manufacturers guarantee, ensuring its performance in all weather conditions.

    Q. Is this technology available for other surfaces?

    ProPERLA super hydrophobic technology is available in clear or coloured forms for a wide range of substrates including roof tiles, masonry & wood.

  4. Impregnator Vs Sealer – What Is The Difference?

    Leave a Comment

    'Impregnator', 'sealer', even 'impregnating sealer' are all terms you will see a lot when researching exterior waterproofing treatments & coatings. But what is the difference between them? In this guide we are going to answer all of the most common questions regarding impregnators & sealers so you can find the right waterproof treatment for you.

    The Background

    In the UK, our homes must endure large amounts of rain & weathering almost all year round. For this reason, protecting exterior surfaces is something that many homeowners want to do in order to protect their home.

    Contrary to popular belief, mineral building materials such as brick, concrete, stone, paving, roof tiles & wood are all porous, meaning they absorb moisture. The more porous a surface, the more liquid or gas can pass through voids & be held in the material.

    Moisture is the single biggest cause of building material deterioration. This is because when the temperature drops, any moisture that is present in building materials, whether it is masonry or roof tiles. can undergo a freeze-thaw cycle. 

    This is the process in which moisture freezes from a liquid into a solid, causing it to expand. The result of this is that the water within building material expands when it freezes. This movement causes cracks in the material to open up, allowing more moisture to enter and continuing a cycle of deterioration. With masonry surfaces particularly, the moisture within the material can also lead to the strength of the mortar within the brickwork to weaken.

    Moisture can also create the ideal environment for moss, lichens & other green growth to develop on & in-between building materials. In the case of roof tiles, by growing in the gaps between roof tiles, moss can compromise the ability for your roof to keep out moisture. If moss is allowed to grow on your roof, the moisture that the moss soaks up can cause roof tiles to rot due to the consistent exposure to moisture. Furthermore, the growth of the moss will fill the gaps between the roof tiles, which can move & damage the roof tiles. This is because the moss soaks up water & expands, which can compromise the bond between the adjoining materials that ensure the integrity of the roof. Eventually, roof tiles can crack under the movement.

    Lastly, exterior surfaces, especially in the wet conditions here in the UK, can be left discoloured from moisture stains. Furthermore, the moisture can provide the perfect conditions for moss, lichens & other green growth to thrive, causing a significant loss to the kerb appeal of paving, timber, masonry & roof tiles.

    In summary, there are a whole host of problems that are associated with water ingress on building materials, which is why preventing this moisture is crucial if you want dry, clean & protected exterior surfaces.

    Impregnator Vs Sealer

    This is where waterproofing treatments come in, which are designed to prevent this water ingress and keep exterior surfaces dry.

    Unfortunately, in the UK there is a lot of conflicting information regarding waterproofing treatments, with many people confusing sealers & impregnators. These both refer to clear waterproofing treatments that are used to prevent water absorption.

    Sealer

    Sealers refer to water repellent treatments that prevent water absorption. They achieve this by creating a waterproof film on the surface of the material.

    While preventing water absorption, these sealers do what the name would suggest, which is seal the surface. This sealing film that is created can impact the breathability of the material, preventing water vapour from freely passing through the surface. By preventing this breathability, any moisture that finds its way underneath the film from any hairline cracks becomes trapped. Eventually, the build-up of moisture will cause the film of the sealer to break under the pressure & leave the surface unprotected once again. Think of wrapping a surface in cling film. Yes, it will prevent water getting in, but it will trap anything inside from escaping.

    In the case of masonry, apply a sealer can be particularly detrimental to the health of the property. By sealing the surface and not allowing water vapour to escape, moisture that naturally occurs from condensation within the property will become trapped. The moisture will build-up within the property and cause significant damp problems, not to mention the breakdown of bricks and mortar from the high levels of moisture. Instead of preventing damage to bricks and damp, which is what they are designed to do, they accentuate these problems even more.

    While these products are often clear, invisible treatments, as they form a film on the substrate they can leave an unnatural sheen on the material which is undesirable for many.

    When they exist in a coloured system in the form of a waterproof masonry paint for example, the build-up of moisture will eventually cause the paintwork to peel & flake off the substrate, leaving an untidy finish on the property.

    A sealer should only be used if you are looking for a short-term waterproofing solution on a small area. Even in this scenario, they should be used with caution.

    Impregnator

    An impregnator is a waterproofing treatment just like a sealer, however it achieves this in a different way. In contrast to a sealer, an impregnator works below the surface of the building material, rather than creating a film.

    It does this by chemically bonding and penetrating into the material. Instead of sealing the pores of the material, it lines the pores. This means that while water cannot enter the substrate, any water vapour can still freely travel through the pores and breathe out.

    The best way to think about an impregnator vs a sealer is that an impregnator waterproofs the substrate itself, while a sealer creates a waterproof film on the substrate.

    Long-term, with no film to break and with the breathability of the building material maintained, the lifespan of an impregnator far exceeds that of a sealer.

    Impregnator:

    • Water Repellent
    • Highly Breathable
    • Lifespan of over 10 years
    • Self-cleaning
    • Penetrates into substrates
    • Does not alter the appearance

    Sealer:

    • Water Repellent
    • Not Breathable
    • Lifespan of over 1-3 years
    • Creates a film on the surface of substrates
    • Offers a clear treatment, although a sheen can be left on the surface
    Clean roof

    Containing the latest nano technology, ProPERLA impregnating treatments create a super hydrophobic surface that repels water, preventing up to 96% of water absorption. This is caused when water droplets are unable to stick to the treated surface, instead simply forming beads on the surface of the paving.

    While preventing water absorption, the impregnators also remain highly breathable, allowing water vapour to naturally pass through the substrate.

    By creating a super hydrophobic substrate that repels water, ProPERLA technology also has self-cleaning properties. This is because any dirt on the surface is simply cleaned off with any rainfall. The super hydrophobic technology also discourages the growth of moss, lichens & green growth, as well as preventing any staining or discolouration from moisture. This significantly reduces the maintenance of exterior surfaces, allowing them to stay looking clean & pristine for decades.

    ProPERLA icons

    ProPERLA super hydrophobic impregnating technology is available for a range of substrates, including roof tiles, brick, concrete, stone, paving & timber:

    • ProPERLA Water Repellent - an advanced clear roof waterproofing treatment for mineral building roof tiles such as clay, concrete, terracotta, natural stone and slate.
    • ProPERLA Masonry Creme - a masonry protection cream that keeps properties warm & dry by creating a super hydrophobic coating on a range of substrates, including brick, stone & concrete.
    • ProPERLA Wood Impregnator - a clear waterproof coating for wood that provides long lasting weather protection for timber, preventing rotting, green growth & discolouration.
    • ProPERLA Paving Impregnator - an advanced waterproof treatment for patios & driveways that provides protection against weathering & discolouration.

    In the case of ProPERLA Masonry Creme, this is our most popular impregnator. This is because of the nature of masonry surfaces. Roughly 35% of all heat loss in a home occurs through the walls which is caused by exterior walls becoming saturated with water. Tests have shown that a damp content of 5% in a plain brick wall can lower the insulation performance by up to 50%. By keeping walls dry, ProPERLA Masonry Creme helps to improve the thermal efficiency of a property.

    In independent testing, ProPERLA Masonry Creme was found to keep a masonry wall 6⁰C warmer on average in comparison to the uncoated walls. For this reason, ProPERLA Masonry Creme has been verified by the Energy Saving Trust following their independent review process.

    Testing conducted also found that both ProPERLA Masorny Creme & ProPERLA Water Repellent have a proven 25 year performance in the harsh weather conditions, ensuring their performance without failing for decades to come. This is in contrast to less advanced sealers that last between 1-3 years.


    How Do I Treat My Surfaces With ProPERLA Impregnators?

    ProPERLA impregnators contain a specialist technology that must be applied by experts in order to ensure maximum performance.

    We have a number of approved ProPERLA applicators up and down the UK who have attended our rigorous training program to ensure they apply the impregnators to the highest level.

    Frequently Asked Questions

    Q. How do I become an approved applicator of ProPERLA products?

    To ensure our products are only applied by trained experts, we ensure that applicators attend our training course in order to become an approved applicator of ProPERLA products. Why not read more about our training course if you would like to be able to offer ProPERLA technology to your clients?

    Q. Does an impregnator alter the appearance of paving?

    By penetrating into the substrate, an impregnator does not leave any finish or alter the appearance of the surface in any way. A sealer may potentially leave a sheen as it creates a film on the surface.

    Q. How long do impregnators last?

    In the case of ProPERLA impregnating products, these have not all been fully tested to their maximum lifespan. ProPERLA Water Repellent & ProPERLA Masonry Creme have both been tested in a 25 year accelerated weathering process that found at the end of 25 years of harsh weather conditions, there was no sign of deterioration in performance or appearance. 

    All ProPERLA products come with a manufacturer guarantee of between 10-20 years, which completely ensures the performance of the product & protects you from any product failure. Having said this, the lifespan of the products far exceed this guarantee.

    Q. Is this technology available in colours?

    ProPERLA super hydrophobic technology is available in coloured form for walls & roofs. While these products remain highly breathable, they must apply a film in order to create a coloured finish, which is why they are not considered impregnators. Having said this, they are not sealers as they still line the pores of substrates without sealing them, meaning full breathability is maintained. 

    Q. Should natural stone be waterproofed?

    We would recommend that you protect any natural mineral surface to ensure they last a long time looking their best. With natural stone being a very porous substrate, it can be particularly prone to water ingress, meaning waterproofing it can be highly beneficial for protecting the surface.

  5. Block Paving Restoration – Everything You Need To Know

    Leave a Comment

    In the UK, our homes have to withstand a barrage of weathering from the elements almost all year round, which can lead to areas of properties showing the effects. One area particularly susceptible to dirt & discolouration is block paving on our driveways & patios, which can leave them top of many peoples list of home improvement projects. In this guide we are going to cover everything you need to know about block paving restoration so you can have a beautiful patio this summer.

    What Is Block Paving?

    Block paving is a commonly used form of pavement that is used for driveways, walkways & patios across the UK. 

    Due to the individual block nature of block paving, each block can be lifted and replaced when they suffer damage or become worn, which is a key reason why block paving is commonly used domestically.

    Block paving generally is made from concrete, although other forms of patio & driveways are made from brick, sandstone & other mineral substrates.

    The Problem With Block Paving

    Block paving as a natural mineral substrate, contrary to popular belief amongst homeowners, will absorb moisture. This is because cement, stone & brick are all porous, meaning water can transfer easily through the pores of the material. The more porous the paving, the more water it can absorb. 

    Moisture is the single biggest cause of building material deterioration. For this reason, this water absorption can cause a real headache for block paving.

    When the temperature drops, any moisture that absorbs into the block paving through pores or through hairline cracks can undergo a freeze-thaw cycle that results in the moisture within paving expanding when it freezes. This movement causes cracks in the block paving to open up, allowing more moisture to enter the material and continuing a cycle of deterioration.

    Moisture can also create the ideal environment for moss, lichens & other green growth to develop on the face of the block paving. Once able to bloom, this will eventually engulf the paving and cause it to lose significant kerb-appeal.

    Lastly, like all exterior surfaces in the UK, block paving can be left discoloured from the dirt that wind-driven rain brings. This dirt attaches itself to the block paving & becomes ingrained in the natural substrate, making it very difficult to keep patios, walkways & driveways looking clean all year round.

    The Solution

    Simply cleaning the block paving will lead to the same discolouration, dirt & green growth that caused the problem in the first place coming back in a matter of time.

    This is where patio sealers & other treatments come in. Sealers & other similar treatments aim to prevent the water absorption of block paving that causes the deterioration.

    Unfortunately, in the UK there is a lot of conflicting information regarding sealers. While these sealers prevent water absorption, they do this by creating a film on the surface of the block paving. This film can impact the breathability of the paving, preventing water vapour from freely passing through the surface. By preventing this breathability, any moisture that finds its way underneath the film from any hairline cracks is trapped. Eventually, after the trapped moisture causes damage to the block paving, the film of the sealer will break under the pressure & leave the paving unprotected once again. 

    While these products are more often than not clear, invisible treatments, as they form a film on the substrate they can leave an unnatural sheen on the paving which is undesirable for many.

    This is why impregnating treatments such as ProPERLA Paving Impregnator were developed. Containing the latest nano technology, ProPERLA Paving Impregnator creates a super hydrophobic surface that repels water, preventing 95% of water absorption. This is caused when water droplets are unable to stick to the treated surface, instead simply forming beads on the surface of the paving.

    While preventing water absorption, the impregnator also remains highly breathable, which is what is unique for a waterproofing solution.

    This is achieved by the treatment impregnating into the block paving, rather than creating a film on the surface, that waterproofs the block paving itself. By chemically bonding to the mineral surface, it lines the pores of paving rather than sealing them, creating a one-way avenue for moisture.


    Block paving waterproofed

    By keeping block paving dry & by giving it a water repellent surface, not only protects paving stones & slabs long-term, but also improves the appearance of them.

    Once applied to paving, ProPERLA Paving Impregnator:

    • Deters the unsightly growth of moss, mildew and algae
    • Prevents stains
    • Protects against the damaging effects of rain and frost damage
    • Improves the long term appearance of block paving by creating a self-cleaning surface

    You may be wondering how a patio or driveway could be self-cleaning? In the same way that water cannot attach itself to the paving, dirt similarly cannot attach to paving once treated. This means that with any rainfall, dirt will simply wash away with the natural slant that all driveways are designed to have to avoid water pooling on the surface. This significantly reduces the maintenance of paving, allowing it to stay looking clean & pristine for decades.

    As a more natural form of waterproofing for paving and by impregnating the paving, it does not form any sheen on the surface, leaving the paving completely natural looking.

  6. Sealing Masonry – Everything You Need To Know

    Leave a Comment

    Whether your home is of solid wall construction or has a cavity wall, the chances are it is vulnerable to water ingress. But what is water ingress & how does it impact the performance of your masonry walls? We have covered everything you need to know in this handy guide, so you can protect your masonry long-term.

    What Is Masonry Sealing?

    Masonry is a term that refers to exterior walled structures consisting of building materials bound together by mortar. Masonry is commonly made from brick, stone, concrete & limestone which all vary in terms of porosity & permeability. 

    Porosity

    You may be wondering, what do we mean by porosity? Well, in short, masonry substrates are not waterproof. Porosity refers to the amount of void space in a material, which is a key indicator of the materials ability to absorb & hold moisture. The more porous a masonry surface, the more water it can absorb. A conservative estimate for the amount of water a weathered brick (over 20 years old) could uptake is 20% its weight in water. This water makes its way through the pores of the material, hence the name porosity,

    Permeability

    Permeability refers to the the extent to which air or water can travel through a substrate. Where permeability comes in to the equation alongside porosity is in terms of 'breathability'. The breathability of a substrate, is a measure of how much water vapour can travel through a substrate. If a surface is not breathable, water vapour from inside the property will slowly build up as it has no escape outlet. Eventually, over time this will cause significant problems to a property that sometimes cannot be undone.

    It is important to note that while similar, permeability and porosity are not the same. Porosity is a measure of how well a material holds moisture, while permeability refers to the ability to transfer water or air through the material. A substrate can be porous while being impermeable if the pores of the substrate do not allow the moisture to transfer right through the wall.

    Brick sealer

    While masonry surfaces as a natural substrate are designed to uptake moisture, with ageing masonry there is a danger that they will hold this moisture over time. When the temperature drops, this moisture can undergo a freeze-thaw cycle that results in the moisture within masonry expanding when it freezes. This movement causes cracks in the masonry to open up & expand, allowing more moisture to enter the building and continuing a cycle of deterioration.

    As well as damage to masonry, water absorption can also lead to a variety of other side affects, including:

    • Heat loss - damp content of just 5% in a plain brick wall can lower the insulation by up to 50%. This is because wet walls transfer heat twice as quick as dry walls.
    • Damp problems - damp content in masonry walls can transfer into the internal wall of a property when the property is of solid wall construction or when it has poorly fitted cavity wall insulation. By filling a cavity wall with insulation, you can end up removing the space necessary for water to freely escape the building.
    • Discolouration - masonry that has been exposed to long-term water ingress can become discoloured by the moisture.
    • Green growth - moisture allows fungal growth such as moss & lichens to thrive on masonry surfaces.
    • Efflorescence - salt deposits caused by water dissolving salts within masonry & depositing them on the outside of the wall are a key indicator of water ingress. While not damaging, it can create a real eye-sore on masonry surfaces of all ages.
    Salt efflorescence on a brick wall

    Masonry Sealers

    This is where masonry sealers come in. Masonry sealers & other similar treatments aim to prevent the water absorption of masonry, preventing the moisture from being held in the brickwork. By preventing water absorption, the masonry is protected from all of the side effects that the moisture can have.

    Unfortunately, in the UK there is a lot of conflicting information regarding masonry sealing. While masonry sealers prevent water absorption, they do this by creating a clear film on the surface of the masonry. This film can impact the breathability of the masonry, preventing water vapour from freely passing through the surface. By preventing this breathability, any moisture that naturally builds up within the structure from condensation will become trapped, along with any moisture that finds its way underneath the paint film from any hairline cracks.

    Eventually, after the trapped moisture causes significant damage to the masonry & extensive internal damp problems, the film of the sealer will break under the pressure. This will leave the masonry unprotected and in a worse state than it started in. Imagine wrapping your exterior masonry walls in a plastic cling film. This would trap moisture in the exact same way as a masonry sealer.

    A masonry sealer should only be used if you are looking for a short-term solution to water ingress on a small section of masonry. Even in this scenario, it should be treated with caution.

    Masonry Creme

    When opting for a waterproofing treatment, you must ensure that it is highly breathable, as not to impact the natural breathability of the masonry.

    Breathability is measured by an SD rating, which is a calculation of how easily water vapour can travel through a surface. A surface or coating is breathable when it has an SD rating of 0.5 or below, as stated by industry standards.

    This requirement of high breathability & waterproof properties is why we developed our super hydrophobic nano-technology here at ProPERLA. Our technology was developed to chemically bond and impregnate into masonry surfaces, rather than create a film on the surface. This lines the pores of brick, concrete, stone & other mineral surfaces without sealing them, preventing water from absorbing into the surface but still allowing water vapour to travel through.

    We took our ProPERLA Masonry Creme to independent UKAS accredited laboratory Lucideon to ask them to test our Masonry Creme for durability, water resistance, heat retention & breathability. In a 25 year accelerated weather test, Lucideon found that after the 25 year period, there were no signs of deterioration in performance or appearance.

    The treatment was found to prevent 96% of water absorption, even after the 25 years. Furthermore, in breathability tests was found to have an SD rating of 0.03, demonstrating the treatment is highly breathable.

    In the test for heat retention, ProPERLA Masonry Creme was found to result in the treated wall being on average 6°C warmer when compared to an untreated masonry wall. For this reason, ProPERLA Masonry Creme was verified by the Energy Saving Trust for its ability to help reduce energy bills & maintain higher household temperatures.

    How Do I Treat My Masonry With ProPERLA?

    Both ProPERLA Masonry Creme and our coloured system ProPERLA Facade Coating are specialist technologies that must be applied by experts in order to ensure their performance.

    We have a number of approved ProPERLA applicators up and down the UK who have attended our rigorous training program to ensure they apply the treatments to the highest level. To find an approved ProPERLA applicator, simply type your postcode in our applicator finder tool and find your nearest applicator, who can carry out the treatment for you.

    Frequently Asked Questions

    Q. How do I become an approved applicator of ProPERLA products?

    To ensure our products are only applied by trained experts, we ensure that applicators attend our training course in order to become an approved applicator of ProPERLA products. Why not read more about our training course if you would like to be able to offer ProPERLA technology to your clients?

    Q. Does ProPERLA Masonry Creme alter the apperance of masonry?

    Unlike masonry sealers that can leave a 'sheen' on brickwork, ProPERLA Masonry Creme does not alter the appearance of masonry in any way. This is because it does not form a film on the surface of the masonry, instead penetrating into the brickwork and waterproofing it from the inside.

    Q. Should you apply waterproofing treatments to new-build properties?

    While new bricks are not as porous as weathered bricks, after a period of time they will become weathered and will start to uptake more and more water. By applying Masonry Creme, you are protecting & investing in the long-term protection of the building. After all, prevention is much easier than restoration.

    Q. Do I need to seal brick & masonry before painting?

    A common misconception regarding penetrating damp prevention & waterproofing is that you have to seal the masonry before painting. By sealing the masonry, you are creating a water repellent layer that will prevent the paint from adhering to the masonry. If you want a waterproofing treatment but also want to then paint this, simply opt for a waterproofing wall coating like ProPERLA Facade Coating. This contains the same super hydrophobic technology but in a coloured form, removing the need to apply two separate coatings.

  7. Roof Cleaning – Everything You Need To Know

    Leave a Comment

    Many homeowners in the UK will be familiar with the sight of moss & other unsightly growth on their roof tiles. This growth can be a real nuisance to prevent long-term, but what causes it & how can achieve a clean roof? In this article we are going to answer some of the most common questions regarding roof cleaning so you can find everything you need to know in one place.

    What Causes Growth On Roof Tiles?

    There are a number of types of unsightly growth on roof tiles which include:

    • Discolouration
    • Green growth & algae
    • Moss

    The root cause of this growth is moisture, which is absorbed by roof tiles from rainfall. This is because the moisture absorbs into the roof tiles, creating the conditions that are perfect for moss & other natural growth to thrive.

    This is contrary to what many believe, as a large proportion of homeowners do not realise how absorbent building materials such as roof tiles, brick & stone are.

    Is Roof Cleaning Necessary?

    Aside from the loss of aesthetic appeal that is caused by a weathered roof, there is a significant performance reason why roof cleaning is sometimes essential.

    When moisture creates the conditions required for spores of moss to bloom on roof tiles, moss can compromise the ability for your roof to keep out moisture. If the moss is allowed to grow on your roof, the moss will fill the gaps between the roof tiles. Gradually over time, this moss can move & damage the roof tiles as it absorbs further moisture and expands, compromising the bond between the adjoining materials that ensure the integrity of the roof.

    The moisture that is uptaken by the moss will also cause deterioration of the roof tiles, as moisture is the single biggest cause of damage to exterior building materials. Tiles can delaminate due to high moisture levels, plus in winter months, freeze thaw cycles can cause further movement of roof tiles.

    Ultimately, moss & green growth is a key indicator of high moisture levels of your roof tiles, which if left over time could lead to enhanced deterioration.

    Roof Cleaning

    While pressure washing was a typically used method of roof cleaning, today dedicated cleaning companies & roof companies use a 'soft wash' method to clean roof tiles. This involves steaming the roof tiles rather than creating a high pressure water stream that dislodges the moss. This is less damaging than pressure washing, ensuring no disruption to the tiles during the cleaning process. 

    While roof cleaning alone can remove large areas of moss growth from the tiles, it does not prevent the potential for further moss growth due to some spores that will remain on the roof. With high moisture levels, the conditions that caused the moss to grow in the first place are still present. Due to that, it is necessary to use a fungicidal cleaner that will kill any natural growth before it can bloom. 

    Due to the technical nature of roof cleaning, it is not advised to clean it yourself, as you can cause further damage by taking it upon yourself to complete the project. We highly recommend getting in touch with a company that offers roof cleaning services, we have access to the right equipment & are experienced with using fungicidal treatments on the roof. 

    As we have mentioned however, cleaning your roof is not the end of moss growth for good. New spores could make their way onto the roof, which can thrive in the high moisture conditions on your roof. For that reason, for long-term moss prevention, you must prevent this moisture.

    Clean roof

    Roof Waterproofing Treatments

    Roof waterproofing treatments are products that create a waterproof barrier on the surface of roof tiles, stopping this transfer of moisture from the external environment into the tile. While there are many of these products on the market that refer to themselves as 'sealers', this is a term that should be treated with caution.

    A sealer is a product that creates a waterproof seal on the surface of the material, that prevents any moisture from entering the material but also prevents any moisture from escaping. This can be terrible for the condition of your roof as moisture will simply continue to build up underneath the seal until either the treatment fails or the tiles becomes damaged, as the moisture attempts to escape.

    This is why any waterproofing treatment for exterior surfaces must be 'breathable'. A breathable treatment is one that has an SD value of under 1, meaning that water vapour can freely travel through the surface, By maintaining breathability, water vapour to escape and maintains a dry material.

    That is why we developed our ProPERLA super hydrophobic technology, which chemically bonds to building materials, lining the pores of the substrate without create a sealing film. While giving water repellent properties to materials, it maintains breathability as it allow water vapour to freely pass through the treatment. ProPERLA treatments have an SD value of 0.01-0.03, demonstrating exceptional breathability.

    We developed this technology for a range of surfaces, including walls, paving, timber & roof tiles. For roof tiles in particular we offer ProPERLA Water Repellent, which is a completely invisible waterproofing treatment and RENOTEC Roof Coating, which is a coloured roof paint.

    In independent tests conducted by UKAS accredited laboratory Lucideon, both RENOTEC Roof Coating & ProPERLA Water Repellent were found to perform for 25 years, ensuring their long-term ability to prevent water absorption and protect roof tiles from deterioration.

    The other huge benefit of ProPERLA super hydrophobic technology is that it creates self-cleaning roof tiles. As water cannot attach itself to the roof tile due to the water repellent properties, dirt & other contaminants are simply washed away with any rainfall. This self-cleaning cycle helps to keep roofs looking pristine for years to come.

  8. ProPERLA Set In Motion Further Testing

    Leave a Comment

    ProPERLA is delighted to announce that we have set in motion the process of rigorous independent testing on ProPERLA roof treatments and wood impregnator, in line with the substantial testing that ProPERLA wall coatings have undergone. 

    Previous testing conducted by Lucideon

    Back in November 2018, ProPERLA approached UKAS accredited laboratory Lucideon to carry out independent testing on ProPERLA wall coatings, specifically ProPERLA Facade Coating and ProPERLA Masonry Creme. 

    Lucideon with their world leading testing facility were tasked with scientifically and impartially testing ProPERLA wall coatings to ensure they are fit for purpose and conform to regulations. 

    Specifically, the tests were conducted to;

    • determine performance after 25 years of accelerated weathering
    • test and analyse thermal insulating properties
    • test and analyse breathability
    • test and analyse the super hydrophobic (highly water repellent) properties of the coatings

    The results of the the test were that ProPERLA wall coatings passed each of the four parameters, achieving the following quality standards:

    • EAD 090062-00-0404 – 25 year hygrothermal performance
    • EAD 040083-00-0404 – External thermal insulation composite
    • BS EN ISO 7783:2011 -  Water vapour diffusion
    • BS EN ISO 12572 - Water vapour resistance

    Independent UKAS accredited testing

    Following the outstanding success of independent testing on ProPERLA wall coatings, we are now beginning the process of having the following products tested:

    1. RENOTEC Roof Coating
    2. ProPERLA Water Repellent
    3. ProPERLA Wood Impregnator

    These products will be tested for their durability (lifespan), ability to prevent moisture penetration and breathability. RENOTEC Roof Coating will also have it's colour fastness tested to identify the coating's ability to maintain its colour and resist UV degradation.

    Lucideon will be developing a custom made roof structure in order to replicate as close as possible the conditions of roof tiles, allowing Lucideon to test the practical performance of ProPERLA roof treatments on roof tiles.

    A wooden structure will also be developed in order to identify the performance of ProPERLA Wood Impregnator as a clear, water repellent treatment for preventing the degradation & discolouration of timber surfaces.

    We are delighted to announce this news to ProPERLA approved applicators and homeowners as we believe this testing will further validate the superior performance of ProPERLA's super hydrophobic technology. 

    The testing process is in immediate planning, with the accelerated weathering process potentially due to begin within a matter of weeks.

  9. Roof Replacement – Is It Worth It?

    Leave a Comment

    With any building material, there comes a time when they are looking tired and in need of upgrading. This is especially the case with roofs as they take a huge mount of punishment from the elements, whether in a warm country due to the heat or a wet country such as the UK. That is why a roof replacement is something many people consider in order to upgrade the performance and the appearance of their roof, breathing a new lease of life into a property. In this guide we are going to discuss roof replacements and whether they are really worth it, so you can decide on the best course of action for you and your home.

    What is a roof replacement?

    Firstly let's establish what exactly a roof replacement is. As the name would suggest, a roof replacement involves the process of removing everything on the roof down to the deck, which is then followed by putting on new layer of felt paper down and then the installation of new roof tiles.

    An alternative form of roof renovation is roof repair, which is a better option than an entire roof replacement if a roof is not damaged on a large scale. 

    When should I replace my roof?

    There are a number of situations that will decide whether you will need to replace or roof, or simply undertake remedial works on your roof:

    • Roof age - if your roof is older than 20-25 years, this is often the recommended age in which a roof may require to be replaced.
    • Roof sagging if your roof tiles are beginning to sag or bow in the middle, this is something that could lead to structural damage and will need to be resolved through roof remedial or replacement.
    • Blown or missing tiles - any missing tiles is something that much be rectified as soon as possible by a remedial work, or if it is large scale then potentially a roof replacement. The same goes for blown roof tiles that have been damaged by moisture or moss growth. When moss grows, it absorbs moisture which causes roof tiles to lift away from the other roof tiles, causing significant damage.
    • Water damage if there a clear stains on your interior ceilings or walls, this is a direct indication that your roof may be leaking.

    A roof replacement is a big task and is one that we all want to avoid if possible. If there is a structural problem with your roof such as it sagging or tiles missing, this must be addressed by a roofing specialist.

    How much does a roof replacement cost?

    A roof replacement is not a quick job. Roofcosts.co.uk estimate that the replacement of a whole roof on a semi-detached three bed property using plain slates costs on average £5550 which could grow to £8,250 on a larger property, using a natural slate roof tile.

    This is due to all of the costs involved, not only from labour costs and scaffolding costs but of material costs from all new roof tiles.

    The size of the property and the quality of the materials used will significantly change the price of a roof replacement, so it is extremely difficult to estimate the exact price your roof would cost to be replaced.


    Advantages & disadvantages of a roof replacement

    There are a number of advantages & disadvantages of a full roof replacement:

    Advantages

    • It can add value to your property, especially if your old roof was a significant eye-sore and had structural issues that would be off-putting to potential buyers
    • If leaks are being caused by a fault in the roof, then the quicker this is solved, the less 2nd hand damage and remedial costs will be incurred.

    Disadvantages

    • They can be extremely costly, often unnecessarily.
    • Replacing a roof is a large operation that takes many men and a large amount of disruption to your home.
    • There are cheaper alternatives that are suitable for many people that opt for a roof replacement

    In summary, there are a number of situations in which a full roof-replacement is recommended, however not in all cases. Often, problems relating to moss growth, moisture & the appearance of a roof can be resolved without replacing your current roof tiles, which is a large scale renovation job. But what is the alternative? 

    Roof replacement alternatives

    If your roof is not having any structural issues such as a sagging roofline or large scale damaged roof tiles, then there are much more cost effective solutions to improving the appearance of your roof and protecting it from the elements.

    It is a commonly held opinion that roof tiles are waterproof, however the truth is that they are porous, meaning they absorb moisture. This moisture leads to damage & decay of roof tiles as moisture is the route cause cracks to roof tiles. When these cracks appear, moisture and moss get between these cracks, which when the freeze they expand, causing the crack to get even larger. This continues until a large amount of moss covers your roof and it losses its integrity.

    This is where waterproof technology comes in. The super hydrophobic technology developed by ProPERLA is the most advanced waterproof technology available in the UK today. This technology is contained in a range of roof coating treatments that protect roof tiles and enhance their beauty.

    Applying a roof coating has a number of other benefits:

    • Allows moisture to repel straight off the roof tile before it absorbs into the material
    • Creates a self-cleaning surface as dirt particles are repelled from roof tiles with any rain fall 
    • Extends the lifespan of roof tiles as moisture is the biggest cause of roof tile failure
    • Makes it difficult for the growth of algae, lichens or moss on the roof tiles
    • Helps to prevent discolouration and salt efflorescence

    ProPERLA's super hydrophobic technology is available for a range of materials such as roofs, exterior walls, wood & paving. In particular, there are two forms of waterproofing products for roofs; ProPERLA Water Repellent and RENOTEC Roof Coating.

    While ProPERLA Water Repellent is a clear, invisible system that helps to protect roof tiles from water damage, RENOTEC Roof Coating is a popular choice with homeowners who want to transform their roof tiles without paying for a hugely costly re-roofing of their home. 

    Both of these products come with a 10 manufacturers guarantee as they have been independently certified following rigorous testing.

    RENOTEC is available in seven popular colours that are designed to match any property. Red Brown & Rustic shades are two of our most popular colours as they provide a beautifully traditional look to any property. For something more modern, Anthracite & Black Blue also prove extremely popular. These shades work perfectly with white rendered properties, and can really provide a huge kerb appeal. Roof coatings are the perfect product not only for painting roofs in an attractive colour, but providing long-term protection.

    ProPERLA Water Repellent

    While the clear ProPERLA Water Repellent does not alter the appearance of roof tiles, as with any coating, dirt and grime must be washed off before it is applied. This means that the roof must be cleaned of any moss, dirt or algae by a professional before being coated with the ProPERLA Water Repellent, which creates the self-cleaning, waterproof barrier on the roof tiles that keeps them looking pristine for years to come. This is due to the moisture not being able to cause the moss growth and discolouration to the roof tiles that it can cause on untreated properties.

    Once this is done, it is astonishing the difference it can make to a roof. The colour of the roof tiles beneath can provide a beautiful new look to your home, while offering a more natural finish to the roof tiles as they will still vary in shade from one another. This is particularly useful for older properties that benefit from a more rustic finish to the roof tiles.

    Roof coating Vs roof replacement

    You may be wondering how having a roof coating applied to your property will differ compared to having a roof replacement. Here are the main differences;

    • Time - a roof coating takes a fraction of the time of a roof replacement.
    • Cost - as we have discussed, a roof replacement can be a hugely costly renovation work to carry out due to the time it takes and the materials needed. Coating a roof is a cheaper alternative as it does not require the same level of materials as it is applied to the existing materials. Furthermore, it involves less labour costs due to the quicker turnaround.
    • Preservation - one of the key benefits of ProPERLA Water Repellent is that it does not affect the appearance of the original roof tiles. For older properties, a more natural and rustic look can be achieved by simply protecting the roof tiles with a waterproof treatment.
    • Ease - If your house is listed or in a conservation area then you need to check whether you will need any planning permission to re-roof your house.
    • Disruption - replacing a roof causes significant disruption. while a roof coating minimises this as it is applied to roof tiles by not disturbing the roof itself.
    • Protection - while a new roof will provide protection from the elements, eventually this will undergo the same deterioration process of your old roof tiles, eventually leading to damage once again.
    • Structural issue - as we have mentioned, coating your roof will not solve any structural issues with your roof. These should be resolved before you attempt to coat your roof. 


    How to get your roof coated

    We do not advise that you attempt to coat your roof using specialist treatment such as ProPERLA, as there are countless things that can go wrong.

    Frequently Asked Questions

    Q. How often should roof be replaced?

    It is recommended that a roof should be replaced every 25 years, but in truth some roof are built to higher standards than others. If you roof is in good condition, you do not require a roof replacement for the sake of it. These are the properties that benefit from a waterproof roof coating the most, as they will have their lifespans extended for years to come.

    Q. How long does a roof replacement take?

    The size, weather and other factors will all play a large role in how long a roof replacement will take, but it could take up to a week to complete a full replacement.

    Q. Does insurance cover roof replacement?

    As with many insurance policies, homeowners insurance policies tend to cover roof replacements only if the damage was caused by a sudden accident such as a storm. Most damaged roofs are caused by long-standing moisture ingress causing them to decay over time. This means that it many be unlikely that you can claim for this, and is something you will have to pay for yourself.

    Q. How long does roof coating last?

    All roof coatings depending on their quality will vary in lifespan. The roof coatings at ProPERLA come with 10 year manufacturer guarantees, although they will likely exceed this. 

    Q. Do roof coatings stop leaks?

    Roof coatings help to prevent the ingress of moisture on roof tiles by creating a waterproof barrier. There can be some underlying structural problems that a roof coating cannot resolve which must be addressed also. The process of roof cleaning that is required before coating the roof can also help to prevent leaks.

  10. The Truth About Waterproofing A Roof

    Leave a Comment

    Maintaining the integrity of your home is one of the most important aspects of being a homeowner and can be one of the most stressful. We all want to keep our home protected, by how do you do this, and especially without breaking the bank.

    This is where roof waterproofing treatments come in, as they provide an effective solution for any roof, whether new or old.

    What is a roof waterproofing treatment?

    Firstly let's establish what exactly a roof waterproofing treatment is. These treatments come in a range of forms, that can generally be put into two categories; roof coatings and roof sealers. These treatments are often called different things, however essentially a roof coating is a coloured roof paint, while a roof sealer is a clear, invisible waterproofing treatment that does not alter the appearance of the roof.

    Roof waterproofing products are designed to prevent moisture from absorbing into a roof tile. This is contrary to popular belief, with many homeowners believing that their roof is already waterproof. The truth is that roof tiles, like most building materials are porous, meaning they absorb some level of moisture. This moisture causes significant damage to roof tiles, causing cracks along the tiles, allowing moss to grow, and generally weakening the strength of the roof.

    Untreated roof tiles suffer from a range of problems, including:

    • When a roof is left untreated, moisture can find its way into any gaps between roof tiles, which when it freezes expands, causing hairline cracks in the roof tiles to grow larger.
    • High moisture conditions are perfect for moss to grow, which lifts roof tiles away from each other when it grows, increasing the likelihood of damage.
    • UV degradation can cause discolouration of the roof tiles

    This is why waterproof technology has been developed for roof tiles, in order to help protect and restore new and old tiles.

    The truth about waterproofing a roof

    All waterproof technology has come under fire over the years, with roof waterproofing treatments being no exception. This bad press has come from the introduction of the term 'sealer'. A traditional sealer waterproofs a surface by 'sealing' it, thus not allowing water to absorb into the surface. This attempts to prevent damage and decay that moisture causes over time. Unfortunately, many of these sealers over the years, and still today, while they prevent moisture from entering the material, also prevent moisture from escaping from inside the sealed surface. This traps moisture inside a property, which can be hugely damaging to the material and can cause problems such as damp.

    Due to these non-breathable roof waterproofing treatments, many have been led to believe that all of these products are 'sealants' and therefore will be hugely damaging when applied to a roof.

    This is why the latest roof waterproofing technology has been developed, in order to ensure that the breathability of the roof is not compromised once the waterproofer is applied. To be considered breathable, a waterproofing treatment must have an SD rating of below 1. If it has an SD rating of below 1, then water vapour can freely breathe out of the roof, maintaining dry building materials.

    If a roof waterproofer or roof sealer does not have an SD of below 1, then you must avoid this completely. It will simply trap moisture inside your property, simply making any damp problems worse, as we have discussed.

    What's the best breathable waterproofing treatment?

    The super hydrophobic technology developed by ProPERLA is the most advanced waterproof technology available in the UK today. 

    The super hydrophobic technology consists of the latest nano-technology that lines the pores of exterior surfaces without sealing them. This is achievable as water vapour is small enough to breathe through the treatment, while water particles are too large, thus why they are repelled.

    Waterproofing a roof using ProPERLA's super hydrophobic technology has a number of other benefits:

    • Creates a self-cleaning surface as dirt particles are repelled with any rain fall 
    • Extends the lifespan of roof tiles as moisture is the biggest cause of roof tile failure
    • Makes it difficult for the growth of algae, lichens or moss on the roof tiles
    • Helps to prevent discolouration and salt efflorescence

    ProPERLA's super hydrophobic technology is available for a range of materials such as roofs, exterior walls, wood & paving. In particular, there are two forms of waterproofing products for roofs; ProPERLA Water Repellent and RENOTEC Roof Coating.

    While ProPERLA Water Repellent is a clear, invisible system that helps to protect roof tiles from water damage, RENOTEC Roof Coating is a popular choice with homeowners who want to transform their roof tiles, without paying for a hugely costly re-roofing of their home, which can cost significantly more than simply coating the tiles.

    Both of these products come with a 10 manufacturers guarantee as they have been independently tested and certified following a number of tests.

    ProPERLA Water Repellent has been manufactured in accordance with DIN 4108, which is the European rating for water repellency. and certified in accordance with EN1504-2 : 2005, confirming depth of penetration, water absorption & resistance to alkali.

    RENOTEC Roof Coating has achieved the following quality standards;

    • DIN EN ISO 53054 - Tensile strength
    • DIN EN ISO 7783-2 - Water vapor permeability
    • DIN EN ISO 1062/3 - Water impermeability
    • DIN EN ISO 4624 - Pull-off test for adhesion

    These results confirm that the roof coating not only remains flexible to resist tearing, but it also maintains full breathability, is water repellent and offer superb adhesion to roof tiles.
