Hayward’s mild climate, tall trees, and coastal humidity make it easy for algae, moss, and lichen to grow on rooftops. Those black streaks and green patches you see are not just cosmetic problems they are living organisms feeding on your roof’s surface. At PPWPM (Professional Power Washing & Property Maintenance), we specialize in algae and lichen treatment in Hayward using gentle soft wash roof cleaning that restores your roof’s appearance and protects it from long-term damage.
Why Roof Algae and Lichen Are Common in Hayward?
Homes in Hayward, especially near neighborhoods like Fairway Park, Eden Shores, and Burbank, experience high humidity from Bay breezes combined with pollen from surrounding trees. These conditions allow Gloeocapsa magma, a type of blue-green algae, to spread across shingles and tiles. Over time, it causes dark stains, traps moisture, and reduces roof lifespan. Moss and lichen worsen the problem by holding water against the surface, accelerating wear and roof mold growth.Why Pressure Washing Isn’t Safe for Roofs
Pressure washing can cause serious damage to shingles and tiles by stripping protective granules and breaking seals. While it may remove surface dirt, it often shortens the roof’s life and voids manufacturer warranties. PPWPM uses a specialized soft wash roof cleaning system that relies on low pressure and an eco-friendly roof cleaner to remove algae, moss, and lichen at the root without harming your roof.Our Eco-Friendly Roof Cleaning Process
