A roof treatment is normally the best option when your roof has growth of typical biomass such as moss mould and lichen.
We apply a chemical called Benzalkonium Chloride which is a natural salt based product to your roof which will penetrate into the biomass and its roots.
The treatment is left on the roof and over a 4 – 6 week period will kill off the growth. Now the waiting starts for the rain, wind, and sun to weather away the dead biomass over 8-12 months leaving it moss free for up to 2 years or sometimes longer.
This is often the best option to tackle a very dirty roof which may ultimately need to be pressure washed. Once the roof has been treated and left for a year any residual growth can be re sprayed or water blasted off ensuring a much easier job now that the growth is dead.
N.B The Roof shown above was heavily infected with lichen but was completely clear in 8 months after spraying.
We guarantee effective roof cleaning results you can see the second we leave your home. Our cleaning treatment will add life to your roof by removing the lichen and moss.
