Roof Cleaning in Selden, Suffolk County
Those black streaks on your Selden roof aren't dirt — they're Gloeocapsa magma, a cyanobacteria that feeds on the limestone filler in asphalt shingles. Left untreated, it spreads aggressively across your entire roof, trapping moisture and accelerating shingle degradation. Our veteran-owned roof cleaning team in Selden uses the ARMA-recommended soft wash method to safely eliminate this growth without voiding your roof warranty. We never use high pressure on roofing materials. The result is a dramatically cleaner roof and significantly extended shingle lifespan for Suffolk County homeowners.
