A clean roof looks better and lasts longer!
Depending on the type off roof, we have 2 options to clean then. One method is scraping the moss off using a specialized roof cleaning tool with various blades to fit different roof tiles, other option is to use low pressure steam to clean the roof.
The next stage is then to treat the roof with a biocide to kill off any remaining moss, algae, roots/ spores, lichen etc. this process works over a period of months as it kills off the organic matter and then leaves the weather to do the rest.
After this we then clear the gutters and mess from site and removal off all waste.
Moss growth on roofs has reached unprecedented levels in many parts of the country today. It creates a dull and dirty appearance which can damage roofing materials like tiles, slates, fibre, cement and asbestos, all become dull and weakened by moss growth. Even the thinnest layer of moss is a problem because it acts like a sponge, absorbing water. Frost damage is another problem pushing the tiles up and cracking them.
