Moss Treatment & Roof Cleaning in Blaine
Kill the moss, protect the roof — the PNW way, without a pressure washer. Serving Blaine, Birch Bay, Semiahmoo.
Glacier Roofing provides moss treatment & roof cleaning for homes across Blaine, from Blaine, Birch Bay to Semiahmoo. On the water at Blaine, Birch Bay, and Semiahmoo, roofs face constant salt air and marine wind off Drayton Harbor and Boundary Bay — the harshest coastal exposure in the county.
Moss is the number-one roof killer on shaded Whatcom County roofs. It traps water against the shingles, lifts them, and rots the deck below. Our damp, tree-shaded north slopes — thick under the firs from Silver Beach to the Mount Baker foothills — grow it fast.
Why moss treatment & roof cleaning matters in Blaine
Waterfront salt air at Blaine, Birch Bay, and Semiahmoo corrodes cheap fasteners fast — we spec coastal-rated hardware and coatings for homes near the water. On shaded, conifer-lined Whatcom lots — and anywhere up in the foothills — moss is a when-not-if problem. A yearly treatment costs a fraction of the deck rot it prevents.
What our Blaine moss treatment & roof cleaning includes
- Low-pressure, granule-safe cleaning (no pressure-washing shingles)
- Targeted moss & algae treatment
- Zinc / copper ridge strips to prevent regrowth
- Gutter clearing & debris removal
- Annual maintenance plans for shaded roofs
Blaine price range
$400–$1,600
Gentle treatment + cleaning for an average roof. Heavy moss, steep pitch, and multi-story access raise the range.

Real Blaine roofing questions
“I'm right on the water at Blaine and I want a standing-seam metal roof. What gauge and coating actually holds up to the salt air off Drayton Harbor?”
This close to saltwater we spec 24-gauge steel with a Kynar 500 / PVDF coating rated for coastal exposure, plus corrosion-resistant clips and stainless fasteners. Standard 26-gauge builder panels and cheap fasteners corrode within a few years in the salt zone. We'll walk your specific exposure at Blaine, Birch Bay, or Semiahmoo and pick a system engineered for it.
