Signs It Is Time for Roof Cleaning

Homeowners usually notice roof cleaning is due when dark streaks, green patches, or mottled discoloration appear across the shingles. These stains are typically colonies of algae and moss feeding on the limestone filler within asphalt shingles. Over time, these growths hold moisture against the shingle surface and gradually degrade the material.

If you let these stains sit without treatment, the root systems of moss and heavy algae clusters lift the shingle edges and trap moisture against the roof deck. That trapped moisture leads to accelerated granule loss, premature shingle curling, and potential leaks during heavy rain. Waiting also allows the staining to darken and penetrate more deeply, making the removal process harder on the materials.

When we arrive at a home in Springfield, Chatham, Auburn, Sherman, Rochester, Riverton, Pawnee, or Petersburg, we look first at the pitch of the roof, the type of shingles, and the extent of the staining. We inspect the perimeter for delicate landscaping that needs protection and check for existing damage or loose flashing before we begin.

Instead of high-pressure blasting that strips away the protective granules, we use a chemical soft wash method. We apply a specialized cleaning solution from ground level or low-pressure pumps to kill the algae at the root and rinse it away gently. This process restores the uniform color of the shingles without damaging the surface texture.
