How Black Roof Stains Damage Your Roof
Gloeocapsa magma doesn't just look bad — it eats your shingles.
The Damage Cycle
The algae releases acids that break down the limestone in asphalt shingles. As shingle material degrades, granules loosen and wash away, exposing the fiberglass mat beneath.
Warranty Implications
Many shingle warranties are voided by improper cleaning. Only ARMA-approved soft washing preserves warranty coverage.
Fix It Early
The sooner black streaks are removed, the more shingle life you save. Call Wild West Washing for a free roof inspection.
