Roof Cleaning in Winston-Salem, NC

Soft wash roof cleaning across Winston-Salem, NC, taking black streaks off asphalt shingles without putting pressure on them.

The black streaks are algae, not dirt

What runs down a Winston-Salem roof in dark stripes is an algae that feeds on the limestone filler in asphalt shingles. It holds moisture against the roof and it spreads a little further every season. Scrubbing does not touch it, and a pressure washer strips the granules that keep the shingle waterproof.

Low pressure and a cleaning solution

We apply a soft wash mix at garden hose pressure, let it work through the growth, and rinse. The algae dies and clears off over the following rains. Nothing is scraped and nothing is blasted, so the roof keeps its granules and its warranty.

Where we see it worst

North facing slopes hold the stains longest because they dry slowest. Older neighborhoods with heavy tree cover run the same way. West End, Washington Park, Konnoak Hills and the streets off Robinhood Road and Country Club Road all have mature canopy sitting over the roofline.

What we protect

Plants and shrubs get wet down before we start and rinsed again after. Gutters, downspouts, exposed metal, windows and screens all get rinsed. We work from the ground wherever access allows rather than walking a steep pitch.

When to book

Any dry day above freezing. Spring and fall are the easiest to schedule. If you are selling, do it before photos, because a streaked roof reads as an old roof in a listing whether it is one or not.
