Homeowners in Cherryland often notice dark streaks or green patches on their roofs that don’t seem to go away. These stains are usually caused by algae, moss, or lichen thriving in the area’s humid, tree-shaded environment. Over time, they can damage shingles, weaken your roof, and reduce curb appeal. At PPWPM (Professional Power Washing & Property Maintenance), we specialize in algae and lichen treatment in Cherryland using safe, eco-friendly soft wash roof cleaning methods that restore your roof without the risks of high-pressure washing.
Why Algae and Lichen Are Common in Cherryland?
Cherryland’s climate like cool mornings, shaded streets, and nearby coastal moisture, creates the ideal environment for algae and moss growth. The most common culprit behind black roof streaks is Gloeocapsa magma, a type of airborne algae that feeds on the limestone in shingles. Add in the pollen from local oak and eucalyptus trees, and you have the perfect recipe for roof discoloration and decay. Without professional treatment, these organisms can cause:- Shingle damage by removing protective granules.
- Trapped moisture that accelerates mold and rot.
- Dark streaks that increase roof heat absorption and energy bills.
- Premature aging and leaks from persistent moss buildup.
Why Pressure Washing Isn’t the Solution?
Many homeowners assume that pressure washing is the best way to clean their roof but it can actually make the problem worse. High-pressure water can strip away granules, loosen tiles, and even void roof warranties. For older or delicate roofs in Cherryland, this approach can cause long-term damage. That’s why PPWPM uses a soft wash roof cleaning system, recommended by roofing manufacturers for roof algae removal and lichen treatment that cleans effectively without causing harm.Our Eco-Friendly Roof Algae & Lichen Treatment Process
