Pleasanton’s warm climate, rolling hills, and tree-lined neighborhoods make it a beautiful place to live, but also a prime environment for roof algae, moss, and lichen growth. Over time, these organisms form black streaks, green patches, and white crusts that can weaken your roof and shorten its lifespan. At PPWPM (Professional Power Washing & Property Maintenance), we specialize in algae and lichen treatment in Pleasanton using our proven soft wash roof cleaning process that eliminates buildup safely while preserving your roof’s integrity.
Why Roof Algae and Lichen Grow in Pleasanton
Pleasanton’s combination of morning dew, pollen, and shade from oak and redwood trees creates ideal conditions for algae and lichen growth. The black streaks seen on many roofs are caused by Gloeocapsa magma, a blue-green algae that feeds on the limestone filler in shingles. As it spreads, it darkens roof surfaces, absorbs heat, and traps moisture. Moss and lichen make the problem worse by holding water that seeps under shingles, leading to leaks, mold, and wood damage. Regular roof cleaning prevents these issues and protects your investment.Why Pressure Washing Is Not Safe for Roofs?
Pressure washing might seem like a fast way to clean your roof, but it can cause permanent damage. High-pressure water strips away protective granules, cracks tiles, and loosens flashing. Many Pleasanton homes have tile, shingle, or composite roofs that require care. PPWPM uses a soft wash roof system with low pressure and an eco-friendly roof cleaner to safely remove algae, moss, and lichen at the root without harming roof materials or voiding warranties.Our Safe and Eco-Friendly Roof Cleaning Process
