Roof Cleaning in Flint, MI — Remove Black Streaks & Algae
Those black streaks running down your shingles are a living algae — Gloeocapsa magma — that eats the limestone filler in asphalt shingles and shortens roof life. Our ARMA-approved soft wash treatment kills it instantly with zero pressure, protecting your warranty and adding years to your roof.
How our roof cleaning works
We apply a professional sodium hypochlorite blend at low pressure directly to shingles. Algae, moss, and lichen die on contact and rinse away in the next rain. No walking with hard-bristle brushes, no high-pressure blasting, no lost granules.
Warranty and safety
The Asphalt Roofing Manufacturers Association (ARMA) officially recommends chemical soft washing over pressure washing for asphalt shingles. Our method meets those guidelines, so it will not void your shingle warranty.
Results you can see
Black streaks disappear immediately. Moss and lichen dry out and shed over the next 2–8 weeks. Most homeowners get 3–5 years of clean roof out of a single treatment.
