Your Insurance Policy May Depend on It
Insurance companies across California are increasingly canceling or refusing to renew homeowner policies due to roof condition — specifically the presence of moss, algae, and biological growth that insurers classify as deferred maintenance. If your insurer has flagged your roof, or if you want to make sure they never do, the right response is a professional cleaning performed by a licensed contractor — documented properly and done safely.

The Right Way to Clean and Restore Exterior Building Surfaces
Most of what grows on a roof — the dark streaking across north-facing facets, the green patches in shaded areas, the biological staining that builds up over years — isn’t just surface dirt. Algae, bacteria, lichen, moss, and fungus root into roofing and exterior materials and cause ongoing deterioration that worsens over time.
We are a dedicated exterior cleaning and restoration specialist — roofs, building exteriors, decorative concrete, and natural stone.
