Soft-Wash Roof Cleaning in Greater Sacramento

High pressure tears the protective granules off asphalt shingles, cracks tile, and voids most manufacturer warranties. It is one of the fastest ways to shorten a roof's life. Every reputable roofing manufacturer specifies low-pressure, solution-based cleaning instead — which is exactly what we do.

We apply a roof-safe cleaning solution at low pressure that kills the algae (the Gloeocapsa magma responsible for black streaking) and the moss at the root. As with any soft wash, the staining continues to clear over the following weeks as the dead growth weathers and rinses off in the rain. We protect landscaping below and rinse surrounding surfaces so nothing downstream is affected.

We do not walk a brittle or steep roof unnecessarily, and we are honest about what soft washing can and cannot do — it removes the organic staining and growth, but it does not repair physical damage or restore a roof that is simply at the end of its service life.

Roof algae and moss are not just cosmetic. Moss holds water against the roof and works under shingles, and algae slowly degrades the surface. Clearing them protects the most expensive exterior system on your home — and removes the streaking that drags down the look of an otherwise pristine property.
