Moss removal, gutters and roof repair in Salmon Creek, Vancouver, WA 98686

Drive through Salmon Creek and you pass split-levels from the 1970s, ranches from the 1980s and two-story subdivisions from the 1990s and 2000s, often within a mile of each other. The split-levels tend to have long, shallow roofs with a lower section tucked under an upper wall, and that wall line is a classic leak point. Ranches usually have one simple ridge line and an attached garage roof. The newer two-stories bring more valleys, steeper pitches and more vents. We plan each one differently, from ladder setup and staging to underlayment.

Gutters deserve their own mention here. Many original gutters are sectional, with a seam every ten feet, and sized too small for the debris coming off the trees. When they spill over, water soaks the fascia and runs down the siding. Replacing them with larger seamless gutters and wider downspouts fixes a lot of so-called roof leaks. We also check that each downspout actually carries water away from the foundation.

In a shaded yard, a north-facing roof may not dry fully between November and April. Moss starts as green fuzz along shingle edges, then thickens into mats that lift tabs and trap water. Debris settles behind chimneys and skylights and rots in place. During a hard rain, a valley half full of needles sends water sideways under the shingles. Trees also mean limbs, and the rare ice storm can bring down a big one. Trimming branches back, cleaning twice a year and adding zinc strips does more for a roof here than almost anything else.

We cover plants and patios before any cleaning starts, then remove moss by hand and with soft brushes. We never pressure-wash shingles, since that strips granules. After cleaning we treat the roof and, if you want, install zinc strips near the ridge. Typical ranges for cleaning and treatment run $485 to $1,240 on an average home, with gutter replacement priced by the foot. Use those as a guide; your number comes once we have walked the roof.
