roof soft wash — before / after
‹ ›
Kill the black streaks. Keep the shingles. Soft wash roof cleaning that the asphalt shingle manufacturers actually approve of.
Those black streaks on your roof are Gloeocapsa magma — a hardy algae that feeds on the limestone filler in modern asphalt shingles. Power washing it off shortens the life of the roof. Soft washing kills it at the source and rinses it clean.
We follow the ARMA (Asphalt Roofing Manufacturers Association) recommended approach: low pressure, sodium hypochlorite blend, careful rinse. The streaks are gone the same day. The algae stays gone for years.
Roof washing on the South Coast is almost always a worthwhile investment — coastal humidity feeds algae growth, and a clean roof reads as a maintained property the moment a buyer pulls into the driveway.
