Roof Soft Wash services in Charlotte, NC

The black streaks on your roof are almost certainly caused by Gloeocapsa Magma — a type of cyanobacteria (blue-green algae) that feeds on the limestone filler in asphalt shingles. It spreads via airborne spores, thrives in Charlotte's humid climate, and will not go away on its own. Left untreated, this organism actively degrades your shingles, shortening your roof's lifespan by years. The streaks can be safely removed through professional roof soft washing — a low-pressure process using algaecide-based cleaning solutions that kill the organism at the root. We never use high-pressure washing on roofs, as it strips the protective granules from shingles and voids most roofing warranties. Soft washing is the only method endorsed by the Asphalt Roofing Manufacturers Association (ARMA)

Properly performed roof soft washing will not damage your shingles or void your warranty — in fact, the opposite is true. High-pressure washing on asphalt shingles is what causes granule loss and premature aging. Soft washing uses water pressure no greater than a garden hose, combined with professional-grade cleaning solution, to safely eliminate algae, moss, lichen, and biological growth without physically abrading the shingle surface. Most major roofing manufacturers — including GAF, Owens Corning, and CertainTeed — specifically recommend soft washing as the approved method for roof cleaning, and some warranties require regular cleaning to remain valid. We clean roofs in Charlotte and surrounding areas using fully ARMA-compliant methods

A standard residential driveway in Charlotte typically takes 45 minutes to 1.5 hours to pressure wash professionally, depending on size and condition. Larger driveways, heavily stained surfaces, or those requiring pre-treatment for oil and rust will take longer. After cleaning, concrete needs approximately 24 hours to fully dry before you should park vehicles on it — though foot traffic is generally fine within a couple of hours. If rain is forecasted, we'll let you know — light rain after cleaning doesn't affect the result, but heavy rain immediately after can dilute any post-treatment solutions we apply

Yes — when performed by a properly trained professional. Our roof soft wash process includes pre-wetting all landscaping, shrubs, and grass surrounding your home before we begin. We control runoff carefully and rinse all vegetation thoroughly after completing the roof. Gutters and siding are protected during the process and actually benefit from the cleaning solution that runs off the roof — any algae or mold on gutters is typically eliminated in the process. Our cleaning solutions are biodegradable and designed to be safe for plant life once diluted and rinsed. We've cleaned hundreds of roofs in Charlotte and the surrounding area without a single instance of landscaping damage
