Soft-wash roof treatment that kills the black streaks (and the algae causing them), plus full gutter clean-out so water goes where it should.
Homeowners with black streaks on shingles, overflowing or clogged gutters, or an upcoming home sale or insurance inspection.
Pressure washing a roof destroys shingles and voids warranties — we never do it. Our soft-wash treatment uses the same method shingle manufacturers recommend: low pressure with a cleaning solution that kills the algae, so streaks fade and stay gone longer.
That’s gloeocapsa magma — an algae that feeds on shingles. It spreads until treated.
Treatment kills the growth on contact; heavy streaks fade fully over the following weeks with rain.
Twice a year for most Upstate homes — more if you have overhanging trees.
