Can You Power Wash a Roof? Risks, Safer Options, and Tips
Power washing an asphalt shingle roof can seriously damage your roof. The high temperature of the water and extreme pressure (up to 3,000 PSI) can jeopardize the integrity of your shingles or even the rest of your roofing system. Professional roofers recommend scrubbing with roof-safe detergents, removing dry debris by pointing a leaf blower down the roof, or scheduling professional cleaning instead.
