Restore Your Roof’s Appearance Safely
Those black streaks running down your roof aren’t just unsightly — they’re actually Gloeocapsa magma, a type of blue-green algae that feeds on the limestone filler in asphalt shingles. Left untreated, this algae can accelerate shingle deterioration and reduce your roof’s lifespan.
Compass Exteriors uses a professional soft wash system — not pressure washing — to safely remove algae, moss, lichen, and black streaks from your roof. Our method uses specialized, biodegradable cleaning solutions applied at low pressure, which cleans effectively without damaging your shingles or voiding your manufacturer’s warranty.
Why Soft Wash?
- Safe for all asphalt shingle types — no damage to granules
- ARMA (Asphalt Roofing Manufacturers Association) recommended method
- Kills algae, moss, and lichen at the root to prevent quick regrowth
- Protects landscaping with proper plant protection protocols
- Results visible immediately — your roof looks years younger
