What Are the Black Streaks
on Your Roof?
The dark staining you see on roofs across Greater Cincinnati is Gloeocapsa magma — a type of algae that feeds on the limestone in your shingles. Left alone, it breaks down the granule layer, reduces reflectivity, and shortens your roof's lifespan by years.
Moss and lichen are even worse. They retain moisture against the shingle surface, work their roots into the mat, and cause the kind of damage that voids warranties and triggers premature replacement.
Joe uses a low-pressure soft wash system — not a pressure washer. High-pressure washing destroys granules and can void manufacturer warranties. Soft wash uses a biodegradable treatment solution applied at low pressure that kills the organism at the root and prevents regrowth for years.
