Manufacturer-approved soft-wash chemistry kills algae and moss at the root, restoring shingle life — never high-pressure, never destructive.
Black streaks on your roof are a living algae (Gloeocapsa magma). Pressure washing strips granules and voids the warranty — soft washing kills it at the root with the same chemistry the asphalt-shingle manufacturers approve.
No — soft washing is the method the Asphalt Roofing Manufacturers Association (ARMA) actually recommends. High-pressure cleaning is what voids warranties.
Most streaks disappear within 1-3 rainfalls after treatment as the dead algae releases.
