Those dark streaks on your roof aren’t dirt — they’re algae (usually Gloeocapsa magma), and Asheville’s humidity and shade give it everything it needs to thrive. Left alone, it spreads, holds moisture against your shingles, and can shorten your roof’s life. High-pressure washing makes it worse by stripping the protective granules off your shingles. We use soft washing instead — the method most shingle manufacturers actually require to keep your warranty valid.

Why Soft Washing Is the Only Safe Method for Roofs

Direct high pressure on shingles strips granules and shortens roof life. Soft washing uses a low-pressure application of a cleaning solution that kills algae, moss, and lichen at the root, then rinses away gently. It removes what’s growing, not just what’s visible on the surface — which is why the streaks don’t just come back a month later.

Frequently Asked Questions

Direct high pressure on shingles can strip granules and shorten roof life, which is why roofs should always be soft washed, not pressure washed. Soft washing removes algae and moss safely and is what most shingle manufacturers require to keep a warranty valid.

Algae can return over time, especially on shaded roofs, but soft washing kills it at the root rather than just rinsing the surface, so results typically last significantly longer than a simple rinse.

Yes — we soak plants and shrubs near the roofline before we start and rinse them again after, so cleaning solution doesn’t sit on anything living.
