Signs it is time for Roof Cleaning

Dark streaks, black patches, and green moss on your roof are the clearest signs that it is time for a professional cleaning. These stains are usually gloeocapsa magma, a type of algae that feeds on the limestone filler inside asphalt shingles. In the humid climate around Bellhaven, Carrboro, Hillsborough, Pittsboro, and Mebane, moisture creates an ideal environment for this growth to spread across entire roof slopes.

If you leave these stains untreated, the algae continues to trap heat and moisture on the surface of the shingles. Over time, this constant dampness weakens the material and accelerates granule loss, which shortens the overall lifespan of your roof. Moss is particularly damaging because its roots lift and loosen shingle edges, allowing water to work its way underneath during heavy rain.

When we arrive at your property for an estimate or a scheduled job, we look closely at the type of roofing material, the extent of the staining, and the pitch of the roof. We also check for nearby landscaping, delicate plants, and water sources that require protection before any cleaning agents are applied.

We use a low-pressure chemical soft wash method rather than high-pressure washing. High pressure scours the protective ceramic granules right off the shingles, which causes permanent damage. Our soft wash applies a specific blend of cleaning solutions that kills the algae at the root and rinses it away safely, leaving the shingles intact.
