Roof Cleaning and Soft Wash Treatment in Maryland, Virginia & Washington, DC
Removing built-up mold, fungus, lichen, and black algae streaks safely without high-pressure damage to shingles, slate, or tile.
Safe Soft-Wash Roof Cleaning and Restoration
Black streaks on asphalt shingles and thick green moss on cedar shake or tile roofs are not just cosmetic eyesores. Algae spores feed on limestone filler in shingles, while moss roots lift shingle edges and trap destructive moisture.
Hoover Roofing uses low-pressure eco-safe chemical soft-washing designed specifically for delicate slate, cedar, tile, and asphalt roofs across Maryland, Virginia, and DC. Our treatment neutralizes moss roots without stripping shingle protective granules or cracking slate tiles.
