Why do you use soft washing rather than pressure washing to clean roofs?

The force of pressure washing is too much for roof surfaces and can cause damage to shingles and underlying materials, strip paint, blast window seals, or push water behind siding or into an attic. Soft washing is the safe, gentle, yet very effective alternative for cleaning roofs. It utilizes garden hose pressure and biodegradable soaps to clean and sanitize and help extend the life of your roof.
