Cleaning Questions
Before You Book
Straight answers about roof cleaning and moss removal in Kelso, Longview, and Cowlitz County.
Why does moss grow so much on roofs around here?

Is roof cleaning safe for asphalt shingles?
Done carefully, yes. We aim to remove moss and debris without blasting granules off the shingles. We'll inspect first and tell you if cleaning is enough-or if repairs come first.
