Why You Should Not Pressure Wash an Asphalt Shingle Roof
A roof needs a different cleaning approach from a concrete driveway. High-pressure washing can damage asphalt shingles, so the cleaning method should match the roofing material and the manufacturer’s care instructions.
Start with the roof material and condition
Before arranging cleaning, identify the roofing material and check for loose or damaged areas. Cleaning does not repair a leak or replace worn roofing. If the roof needs repairs, address those concerns before scheduling a wash.
Ask about soft washing
