Lafayette’s scenic hills and shaded tree-lined neighborhoods make it one of the Bay Area’s most beautiful cities. But the same climate that keeps it green also creates perfect conditions for algae, moss, and lichen to grow on rooftops. These organisms feed on roof materials, causing stains, leaks, and long-term damage. At PPWPM (Professional Power Washing & Property Maintenance), we specialize in algae and lichen treatment in Lafayette using our safe and proven soft wash roof cleaning method that restores your roof’s beauty without any damage.
Why Roof Algae and Lichen Are Common in Lafayette?
The combination of morning fog, shaded oak trees, and hillside homes creates an ideal environment for algae and moss to thrive. The dark streaks seen on many Lafayette roofs come from Gloeocapsa magma, a type of blue-green algae that feeds on the limestone in shingles. These stains don’t just look bad; they absorb more heat, raise energy bills, and weaken roof materials over time. Moss and lichen trap moisture, accelerating roof mold and decay if not cleaned professionally.
Why Pressure Washing Isn’t Recommended?
Many homeowners think pressure washing will fix roof discoloration, but it can strip protective granules and loosen tiles or shingles. This type of aggressive cleaning can void manufacturer warranties and cause long-term damage. PPWPM’s soft roof wash system uses a low-pressure rinse and an eco-friendly roof cleaner that kills algae, moss, and lichen at the root. It’s gentle on all surfaces, including asphalt shingles, composite, clay tile, and wood shake roofs.
