Roof Cleaning & Coating across Ontario
Those black streaks aren't just dirt, they are gloeocapsa magma algae eating the limestone in your shingles. We stop it.
Why this service matters, and how we approach it.
Black streaking, moss and lichen are not cosmetic. The algae that cause them feed on the limestone filler in asphalt shingles, literally digesting your roof. Left alone, they can strip 5 to 10 years off your roof's service life.
Our soft-wash treatment uses a sodium-hypochlorite solution applied at low pressure, it kills the biological growth without damaging granules the way high-pressure washing does. For flat and low-slope roofs we also apply reflective elastomeric coatings.
