Roof Cleaning in Riverton
A roof that holds shade in this town streaks black sooner or later. The streaks aren’t dirt; they’re an algae (Gloeocapsa magma) feeding on the limestone filler in your shingles, and the humidity rising off the river grows it better than almost anywhere we work. Moss is the more destructive cousin: its holdfasts lift shingle edges and press a wet sponge against the roof through every season.
Soft Wash, Never Pressure
A pressure washer cleans a shingle roof the way a belt sander cleans a tabletop, by removing the surface. Stripped granules take years off a roof, so we won’t put one near yours. Our crews apply a low-pressure soft wash using the same chemistry shingle manufacturers recommend, let it kill the growth, and rinse gently. Streaks vanish the same day; thick moss browns and releases over the following weeks instead of tearing granules away with it.
Keeping It Clean
Zinc or copper strips at the ridge slow regrowth on shaded slopes, and a standing maintenance plan can fold a cleaning into the annual visit. If the troughs below are packed too, gutter repair rounds out the trip. The method, plus before-and-after photos, lives on our roof cleaning page, and the rest of our work in town is under Riverton.
