This might be the most important thing you read about roof maintenance: never let anyone pressure wash your roof. Here's why.
What High Pressure Does to Shingles
Asphalt shingles are designed to withstand rain, not concentrated high-pressure streams. Pressure washing strips away the protective granule layer, voids your manufacturer's warranty, and can blow water under shingles causing leaks and rot.
The Safe Alternative: Soft Washing
Soft wash roof cleaning uses low-pressure application (essentially a garden-hose level of pressure) to apply specialized cleaning solutions that kill algae, moss, lichen, and mold. The chemicals do the work — not force.
Industry-Approved Method
The Asphalt Roofing Manufacturers Association (ARMA) specifically recommends low-pressure chemical treatment as the only approved cleaning method for asphalt shingle roofs.
Meanwhile, hard surfaces like your driveway and patio are perfect candidates for high-pressure cleaning. And your home's siding should also be soft washed for safety.
