Moss Treatment & Roof Cleaning in Lynden
Kill the moss, protect the roof — the PNW way, without a pressure washer. Serving Lynden, Berthusen, Northwood.
Glacier Roofing provides moss treatment & roof cleaning for homes across Lynden, from Lynden, Berthusen to Northwood. Lynden’s open farm country leaves roofs exposed to wind across flat fields — and to the hard northeast outflow winds that pour down the Nooksack and Fraser valleys every winter.
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 Lynden
Flat, open farmland offers no wind break, and the Fraser/Nooksack outflow can drive brutal cold NE gales through Lynden — wind-rated fastening is not optional here. 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 Lynden 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
Lynden price range
$400–$1,600
Gentle treatment + cleaning for an average roof. Heavy moss, steep pitch, and multi-story access raise the range.

Real Lynden roofing questions
“The last outflow windstorm tore a bunch of shakes off the exposed slope of my cedar roof out in the fields. Can you just replace those, or do I need a whole new roof?”
If the deck and the majority of the field shakes are still sound, a targeted repair is usually the right call and far cheaper. We'll pull a few shakes to check the underlayment and fasteners first. Open Lynden farm country takes the brunt of the Fraser/Nooksack outflow winds, so if the cedar is broadly at end-of-life we'll show you the photos and be straight with you rather than patch a roof that'll fail again next winter.
“I'm buying a place outside Lynden and my agent wants a roof report before closing. Can you get out there and turn it around fast?”
Yes — real-estate roof reports are something we do a lot of. We inspect the roof, flashing, and accessible deck, photograph everything, and give you a written report you can hand your agent and lender. We prioritize these so they don't hold up your closing, anywhere in Whatcom County.
