  1. Moss On Roofs – The Ultimate Guide

    Leave a Comment

    Moss, green growth, algae and lichens can be a real annoyance to many homeowners. It attaches itself to the roof tiles due to moist conditions, often ending up causing problems to your roof tiles & gutters. In this article we are going to give you all the information you need to say goodbye to moss on your roof!

    What causes moss on roofs?

    Like any weed, moss releases spores that cause it to spread easily, especially in wet & cold areas. What makes roofs susceptible to moss is the large number of nooks & crannies that allows the moss to attach to the surface. Furthermore, roof tiles are often made of porous materials, making them the perfect material for moisture, and thus weeds. This allows them to spread quickly & effectively across the roof in-between the roof tiles.

    Is moss on roof tiles a problem?

    Yes, moss can cause significant issues for your roof tiles. By growing in the gaps between roof tiles, moss can compromise the ability for your roof to keep out moisture.

    It does this in two ways. If moss is allowed to grow on your roof, the moisture that the moss soaks up can cause roof tiles to rot. Secondly the growth of the moss and the moisture it brings will fill the gaps between the roof tiles, which can move & damage the roof tiles. This is because the moisture can compromise the bond between the adjoining materials that ensure the integrity of the roof.

    In many cases small amounts of moss can be a small eye sore, however if left the develop, it can become an unnecessary issue for your home.

    What is the best time of year to remove moss from roofs?

    If you want someone to remove the moss from your roof, the best time to do this is summer. The summer months, while the weather is dryer, is definitely the best time of year to any exterior cleaning work carried out. This is especially the case if you are planning on removing moss yourself, which we would not recommend, but certainly would advise against during winter or autumn.

    How do you prevent moss on a roof?

    We often get asked 'how do I get rid of moss on my roof?' Firstly, the roof must be cleaned to remove any moss attached to the roof tiles. In cases where the moss growth is not large scale, it can be cleaned off using a hose pipe. Do not use a pressure washer as this will damage your roof tiles.

    If the case is more substantial, then it is wise to use a professional. A company who specialises in roof cleaning will be able to effectively clean the moss from your roof tiles. 

    However, just cleaning the roof is not enough. The cause of the moss still exists, and in a number of years the moss will be back. To prevent moss from growing on roof tiles, we have developed a number of highly advanced treatments that deal with the problems associated with moss growth.

    Our super hydrophobic roof coatings create a waterproof & self-cleaning surface on roof tiles, meaning not are the issues that cause moss dealt with, but moss and any other dirt cannot attach to the roof tiles.

    It achieves this thanks to the latest nano-technology that creates a super hydrophobic surface on roofs, which completely repels water, dirt & moss.

    The treatment is also highly breathable, meaning moisture can escape from inside the property. This is in stark contrast to roof 'sealants' that seal moisture under the surface of the roof, leading to significant damage.

    ProPERLA roof treatments come in two forms; a coloured roof paint & a clear roof treatment.
