Local Details
More shade and more evergreens mean moss is the number one exterior problem in Maple Valley. Moss holds moisture against shingles, lifts their edges over time, and spreads onto siding, fence lines and concrete. Cleaning it off is far less expensive than replacing what it damages.
Roofs here are cleaned with a low-pressure soft wash rather than a pressure washer. That removes the moss and the dark streaking without blowing away shingle granules or voiding a roofing warranty. Siding and trim get the same gentle treatment; driveways, patios and walkways get pressure washing with a surface cleaner for an even result.
Because so many Maple Valley homes sit under mature trees, gutter cleaning usually pairs well with a roof wash. Clearing the gutters and downspouts at the same visit keeps water moving away from the roofline and foundation.
