FAQ
Roof Cleaning questions, answered.
Gloeocapsa magma — a cyanobacterium that feeds on the limestone filler in asphalt shingles. It thrives on north-facing and shaded slopes and creates the dark vertical streaks visible from the curb. Left alone, it shortens shingle life and can void manufacturer warranties.
Not when soft-washed. Our ARMA-approved soft-wash method runs at under 100 PSI — gentler than a garden hose — and uses biocide chemistry to kill algae at the root. Pressure washing damages shingles; soft washing doesn't.
Pressure washing strips the protective granules off your shingles and voids most manufacturer warranties. Soft wash roof cleaning uses low pressure plus biocide chemistry — the only method endorsed by the Asphalt Roofing Manufacturers Association (ARMA).
Most roofs stay clean for 3–5 years after a single soft-wash treatment. North-facing slopes, shaded roofs, and homes under heavy tree canopy may regrow algae sooner — those benefit from a maintenance soft wash every 2–3 years.
Yes. We use biodegradable chemistry, rinse landscaping before and after the wash, and tarp sensitive specimen plants on request. Runoff is plant-safe at the dilution we apply.
Late spring through early fall — temperatures above 5°C let the biocide dwell properly. Most Toronto homeowners book May–June or September–October for best results.
Yes — dramatically. A roof cleaning typically runs 2–5% the cost of a full roof replacement and adds 5–10 years of usable life by killing algae at the root. Most homeowners book a soft wash to delay replacement and protect manufacturer warranty coverage.
