Those Black Streaks Are Algae, Not Dirt

The dark streaking common on shingle roofs throughout Chattanooga and North Georgia is usually Gloeocapsa magma, an algae that feeds on the limestone filler in asphalt shingles. Left untreated, it spreads, holds moisture against the shingle surface, and can shorten your roof's lifespan. Pressure washing a roof can strip the protective granules right off — which is why we exclusively use soft washing on every roof.

Roof Cleaning FAQ

Common questions about roof cleaning

High-pressure washing can strip granules and shorten shingle life, which is why we only use low-pressure soft washing on roofs — it's the method recommended by most shingle manufacturers.

Most residential roofs take 1–3 hours depending on size, pitch, and the amount of algae and moss present.

Algae can return over time, especially on shaded north-facing roof sections common in the Chattanooga area, but soft washing kills it at the root so regrowth is typically much slower than after a simple rinse.
