Metal roofing in Sagle, ID

Sagle is unincorporated — no city council, no city building department, no single published city snow load. Bonner County governs, and the county requires design to the specific parcel. That is not a technicality here: Sagle spreads from the shore of Lake Pend Oreille — Idaho's largest lake, 148 square miles and 1,150 feet deep — up into the hills behind it, and the load at the waterline is not the load a thousand feet above it.

The University of Idaho's 2015 study has no Sagle station. The nearest ones bracket it: Sandpoint 56 psf five miles north, Kootenai 57, Hope 69 further east. Anyone who quotes you a single Sagle number is guessing. What is not a guess is the mechanism — snow held on a warm asphalt deck melts, refreezes at the cold eave, and dams water back under the courses. Standing-seam metal sheds it before that can start, it's Class A fire-rated for the timber, and it lasts 40–70 years on a lake where re-roofing is a genuine production.
