Those Black Streaks Aren't Dirt — They're Alive
The dark stains running down your roof are Gloeocapsa magma, a hardy algae that feeds on the limestone filler in asphalt shingles. Rinsing won't touch it, and it doesn't stay put: it spreads across the roof and onto neighboring homes.
- Spreads wider every season if left untreated
- Drags down curb appeal and home value
- Triggers HOA violation letters
- Traps moisture and shortens shingle life
Got an HOA letter about your roof? We can usually get you compliant within a week.
Why Soft Washing — Not Pressure Washing
A standard pressure washer blasts the protective granules right off your shingles and can void your roof warranty. Supreme Power Wash uses a low-pressure soft-wash method — less force than a garden hose — paired with manufacturer-approved cleaning solutions that kill the algae at the root so it stays gone longer.
