The black streaks running down roofs all over Rockingham County, NC are a living algae called Gloeocapsa magma. It spreads on the wind, feeds on the limestone filler in asphalt shingles, and loves our humid Piedmont summers. Left alone, it holds moisture against your shingles and makes an otherwise good-looking home look neglected from the street.
Why You Should Never Pressure Wash A Roof
High pressure strips the protective granules off asphalt shingles, which shortens roof life and can void your shingle warranty. It also doesn't kill the algae, so the streaks come right back. The shingle industry recommends a cleaning solution applied at low pressure — which is exactly what a soft wash is. Read our full guide to roof algae and black streaks.

Our Roof Washing Process
Pair It With A House Wash
Roof algae almost always has company on the siding and in the gutters. Bundling your roof with a house wash and gutter cleaning costs less than booking each one separately. See our package pricing.

Frequently Asked Questions
Is soft washing safe for my shingles?
Yes. Soft washing uses low pressure and a properly diluted cleaning solution, which is the method the asphalt shingle industry recommends. It does not strip granules the way pressure washing does.
Why shouldn't I pressure wash my roof?
High pressure knocks the protective granules off asphalt shingles, can void your shingle warranty, and doesn't kill the algae, so the black streaks come right back.
How long does a roof soft wash last?
Because soft washing kills the algae at the root, results last far longer than pressure washing. Most roofs stay clean for several years, depending on shade and moisture.
Will the streaks disappear right away?
Most of the streaking fades the day of the wash. Any remaining staining keeps fading over the next few rains as the dead growth washes away.
