Metal roofing in Clark Fork, ID

Clark Fork is the last town before Montana, tucked at 2,085 feet where the Clark Fork River enters Lake Pend Oreille with the sharp-peaked Cabinet Mountains rising immediately east. It carries a 71 psf ground snow load (University of Idaho, *Ground Snow Loads for Idaho — 2015*) — well above Sandpoint's 56, because storms stack against the Cabinets and unload here rather than pushing through.

A timber town since 1893, when three shingle mills ran here, Clark Fork today is about 560 people and a lot of older frame houses under a serious winter. Snow held on an asphalt roof melts against the warm deck, refreezes at the cold eave, and dams water back under the courses. Standing seam sheds it before that starts, and it's Class A fire-rated — which counts in a narrow valley with national forest on both walls. Bonner County requires design to the parcel, so nothing here is engineered to a generic number.
