Those dark streaks and green-black patches on your roof aren’t dirt — they’re algae, moss, and organic growth that feed on the limestone filler in asphalt shingles. Left untreated, they trap moisture, accelerate shingle wear, and hurt your home’s curb appeal. ROOFWORX now offers professional roof soft washing to safely remove algae, black streaks, and organic growth — restoring your roof’s appearance without damaging your shingles.
What Is Soft Washing?
Unlike high-pressure washing — which can strip granules and damage shingles — soft washing uses a low-pressure application of a specialized cleaning compound and spray that eliminates organic growth at the source. The treatment kills algae, moss, and mildew on contact and continues working after application, giving you a longer-lasting clean than pressure washing alone.
Why Roof Washing Matters
- Protects your shingles — organic growth traps moisture against the roof surface, accelerating wear and shortening shingle lifespan.
- Restores curb appeal — removes unsightly black streaks and green patches instantly.
- Safe for your roof — soft washing does not use damaging high-pressure spray like a pressure washer.
- More affordable than replacement — a clean, healthy-looking roof can extend the life of your current shingles.
Roof Washing Pricing
Roof soft washing starts at $3 per square foot of roof surface. Final pricing depends on roof size, pitch, and the extent of algae or organic growth. Call for a free quote or use our roof cost calculator to estimate other roofing projects.
Signs Your Roof Needs Washing
- Dark or black streaks running down the roof slope
- Green or gray patches, especially on north-facing sections
- Visible moss growth near valleys or shaded areas
- A roof that looks dirty or aged despite being structurally sound
Middle Tennessee’s humidity makes algae and moss growth especially common — most homes benefit from a roof wash every few years to keep shingles clean and extend their life.
