Moss Removal That Saves Washington Roofs

WHY IT MATTERS HERE

Moss is the Northwest's slowest roof leak

Shade, fir needles and nine damp months make Western Washington the moss capital of America — and your roof is its favourite habitat. A mossy roof isn't just tired-looking:

• It holds water against the shingles like a sponge, keeping the surface wet long after the rain stops — the exact condition asphalt shingles are designed to avoid;
• It lifts shingle edges as it thickens, opening paths for wind-driven rain to get underneath;
• Its roots break down the granule layer that protects shingles from UV, aging the roof from the surface down;
• It can void warranties — most shingle manufacturers expect the roof to be kept clear.

How we remove it — and how we don't

We never pressure-wash a roof. High-pressure water strips granules and drives water under laps — it trades a moss problem for a roof problem. Our process:

• Mechanical removal with roof-safe brushes and blowers, working top-down with the shingle laps;
• Root-killing treatment applied to the whole field, so remaining spores die and weather sweeps the residue away over the following weeks;
• Gutter and valley cleanout so the debris we remove doesn't clog your drainage;
• Repair on the spot — as a licensed roofing contractor, we fix lifted or cracked shingles while we're up there, and photograph anything you should know about.

Pair moss removal with 5K seamless gutters or a roof assessment and the whole roofline gets handled in one visit.
