Sammamish pressure washing & roof cleaning
The Sammamish Plateau is prime moss country — large newer homes under dense Douglas fir, with steep roofs and long driveways that green up in the shade.
Exterior cleaning in Sammamish, WA
Neighborhoods like Klahanie, Trossachs, Pine Lake and Sahalee sit in heavy evergreen canopy at elevation, so roofs collect needle debris and grow moss and lichen aggressively. The homes are big, the roofs are steep, and the driveways are long and often shaded. Roof soft washing, gutter guard installation and driveway de-mossing are the core Sammamish scope.
Large newer plateau homes under heavy fir canopy with steep roofs. About 40 minutes from our Lake Stevens shop.

Local questions, answered
My roof grows moss back every year — can you slow it down?
Yes. After the soft wash we rinse the roof clean, and for the worst exposures we pair it with gutter guards so needle debris — which feeds the moss — stays out of the system. A light touch-up every year or two keeps it from getting bad again.
