Roof Cleaning & Coating in Whaleys Corners & Ontario
Low-pressure soft-wash roof cleaning that kills the algae feeding on your shingles, plus reflective elastomeric coatings for flat-roof life extension.
Roof Cleaning & Coating, done the way it should be in Whaleys Corners.
Those black streaks running down your shingles are not dirt. They are colonies of gloeocapsa magma, an algae that feeds on the limestone filler in asphalt shingles. Left untreated, the algae digest your roof at a measurable rate, studies have shown 5 to 10 years of lifespan lost on untreated homes over a 25-year period.
Soft-washing is the only safe cleaning method. High-pressure power-washing strips the protective ceramic granule layer from shingles and shortens roof life dramatically, often voiding the manufacturer warranty in the process. Our soft-wash uses a sodium-hypochlorite solution applied at under 300 PSI, which kills the algae at the spore level while leaving the granules intact.
For flat commercial roofs, we also apply reflective white elastomeric coatings. A $3,000 to $6,000 coating on a 5,000 sq ft roof can extend the life of an ageing membrane by 10+ years while reducing building cooling costs by up to 20% in summer.
