Roof Clean and Biocide Treatment to Prevent Regrowth
The organisms on a roof are present due to the warm, moist environment a roof creates, especially on the north and west facing aspects. Roof algae and moss are a nationwide issue, there are several organisms that grow on roofs, one is a bacteria called Gleocapsa Magma.
Other organisms like mildew and algae are unsightly but not as destructive as some of the more aggressive bacteria. Various types of algae, mould, mildew, bacteria, lichen and moss directly decompose and break down the protective surface of a roof tile. The good news is these micro-organisms can be easily treated and safely removed. We can clean your roof and then apply Topseal's Moss Acrylic Roof Sealer Roof Biocide Treatment to prevent regrowth.
