Asphalt Shingle Roof Soft Wash
Asphalt shingle is the most common Tampa Bay roof material — and the most vulnerable to Gloeocapsa magma, the black algae that creates those ugly streaks running down your roof. From $600.
Asphalt shingle is the most common Tampa Bay roof material — and the most vulnerable to Gloeocapsa magma, the black algae that creates those ugly streaks running down your roof. Left untreated, the algae digests the limestone filler in your shingles and shortens roof life by 5–10 years. Soft washing kills it at the root, restores curb appeal, and is the only method approved by GAF, Owens Corning, and the ARMA.
Our approach: Pressure washing voids most shingle warranties and blasts away the protective granules. Soft wash uses chemistry instead of force — kills algae down to the root for 3–5x longer-lasting results.

Gloeocapsa magma — a cyanobacteria that feeds on the limestone filler in asphalt shingles. It's airborne, spreads fast, and left untreated shortens shingle life by 5–10 years by holding moisture against the surface.
No — soft wash preserves it. GAF, Owens Corning, and ARMA all specify low-pressure soft wash as the only approved cleaning method. High-pressure washing (1,500+ PSI) voids most warranties by stripping granules.
18–36 months for most Tampa Bay shingle roofs. We offer a Stay-Clean plan that keeps your roof clean year-round for a flat rate — less expensive long-term than waiting for full regrowth.
Usually yes. Even aging shingles respond well to soft wash as long as there is no active curling, cracking, or bare areas. We inspect before cleaning and will tell you honestly if cleaning makes more sense than replacement.
