Questions homeowners ask
Can a pressure washer clean my roof?
It shouldn't be used on shingles. High pressure knocks off the protective granules and can shorten the roof's life. Reputable roof cleaners soft wash.
Is roof cleaning only about looks?
Mostly, though moss holds moisture against shingles and can lift their edges over time, so removing it helps the roof last.
