WHY YOUR ROOF NEEDS PROFESSIONAL CLEANING IN SOUTH FLORIDA
South Florida's warm, humid climate is the perfect breeding ground for algae, mold, and mildew on roofs. With over 60 inches of rainfall annually and temperatures that rarely drop below 60°F, your roof faces constant moisture and biological growth. That's not just a cosmetic issue — it's actively damaging your investment.
Those black streaks you see on roofs across Palm Beach County? That's Gloeocapsa magma, a blue-green algae that feeds on the limestone filler in asphalt shingles and concrete tiles. Over time, algae eats into the roofing material itself, causing granule loss, premature deterioration, and shortened roof life. Some manufacturers estimate that uncleaned roofs can lose 10+ years of lifespan.
Your HOA may already be citing you. Insurance companies in Florida are increasingly requiring clean roofs for coverage — some insurers now mandate roof cleaning every 1-2 years. Dirty roofs can also void manufacturer warranties. That's why many builders and roofers specify soft wash cleaning as the approved maintenance method.
Pressure Wash of Palm Beach uses 100% soft wash on all roofs — never high pressure. We apply a specialized sodium hypochlorite solution at under 500 PSI, which kills algae and mold at the root without damaging shingles, tiles, or sealant. Your roof gets clean, protected, and your warranty stays valid.
WHAT WE CLEAN
- Concrete and barrel tile roofs
- Asphalt shingle roofs
- Metal roofs (standing seam and corrugated)

SOFT WASH VS. PRESSURE WASH: WHY METHOD MATTERS
High-pressure washing has no place on a roof. Many homeowners don't realize the damage that 2,500–3,500 PSI can do. High pressure drives water under shingles and tiles, damages sealant, strips protective granules, and can cause leaks for years afterward. Major manufacturers including Eagle, Boral, GAF, and IKO explicitly recommend against high-pressure cleaning and state it voids their warranties.
Soft wash is the manufacturer-approved method. We apply our treatment at under 500 PSI — gentle enough that it won't damage anything, but effective enough to kill algae, mold, and lichen at the root. We use a custom sodium hypochlorite solution calibrated for your specific roof type. The biocide works over 48–72 hours, ensuring complete die-off and preventing rapid regrowth.
The result: your roof stays clean longer, your warranty is protected, and there's zero risk of water intrusion. That's the Pressure Wash of Palm Beach standard on every residential and commercial roof we clean.
