NFRC Advises Against Roof Coatings and Paints

National Federation of Roof Contractors logo.The NFRC  (National Federation of Roofing Contractors) recently released a statement about removing roof moss and roof paints.

They advise homeowners to be cautous when dealing with companies that make claims about thermal coatings and possible damage caused by roof moss:

Most ‘techniques’ that we have come across to remove moss, are often achieved by ‘violent’ means such as power-washing, which may cause damage to the roof, especially when combined with unnecessary foot traffic often leading to cracked or broken roof tiles.

The statement also questions claims about thermal roof coatings:

The removal of the moss is often followed up by painting the roof tiles. There are claims that this can increase the thermal efficiency of roofs as well as extending the life of the roof tiles, but unless the products carry credible UK based, third party accreditation we would urge members of the public to view any claims with extreme caution.

The NFRC has also stated that moss growth on roof tiles is rarely a problem and should only be removed if it is blocking gutters and drainage outlets. You can read their advice here.

This advice only confirms the information we have been providing on this website, that moss does not damage roof tiles and using a pressure washer can damage roof tiles and push water into the roof space.

The NFRC was established over 120 years ago and is only the latest reputable body to warn about roof coatings and pressure washing roofs. See what the UK Trading Standards has to say here.

    “The NFRC has also stated that moss growth on roof tiles is rarely a problem”

    Seriously?

    I’ve seen roofs so thick with moss that the roof is bending under the weight of it when wet, roofs where the tiles have lifted because the moss is growing under them and allowing water ingress, gutters full and overflowing all year round, downpipes blocked and fascias rotted because of it!

    Moss is a real problem and in most instances can be dealt with easily and cheaply, and certainly by the methods suggested on this site, but sometimes also by proper and professional pressure cleaning methods.

    I’personally think that it not the product that is the problem, but the the fact that the contractors aren’t vetted and trained to a high enough standard, the product itself if fine, sure some people make ridiculous claims about the products insulation qualities and I should know, I have worked in the insulation industry for 22 years! A piece of paper has thermal resistance. But it has to be said that if you wanted your roof to look like new and the contractor applies the system in the correct manner, it looks good, I like it! Police the industry properly and don’t sell the product to any Tom, Dick or Harry and there wouldn’t be all these problems
