Roofing in Acme and Glacier is mountain roofing, and it needs to be treated that way. Acme sits in the South Fork Nooksack Valley along Highway 9, a landscape of old farmhouses, barns, and river-bottom homesteads. Glacier is the last town on the Mount Baker Highway before the road climbs to the ski area, surrounded by cabins and chalets that catch some of the heaviest snowfall in Washington. A roof detail that works fine in Bellingham can fail outright up here, and Alpine Exteriors builds for the difference.
Snow Load Changes Everything
The foothills of Mount Baker collect snow in quantities coastal Whatcom County never sees, and Glacier area roofs have to carry it, shed it, and survive the melt. Ice dams are the classic failure: heat escaping the living space melts the snowpack from below, the water refreezes at the cold eave, and the resulting dam pushes meltwater backward under the shingles. We counter with continuous ice-and-water membrane run well up the slope, robust attic ventilation to keep the deck cold, and eave details designed for freeze-thaw rather than just rain.
Down-valley in Acme, the pattern is different: less extreme snow, but persistent river-valley damp, morning fog off the South Fork, and moss growth on the many older farmhouse roofs shaded by big maples and cedars. Those roofs usually need full tear-offs, deck repair, and moss-resistant materials more than they need snow engineering.
