Snow and metal roofing near Portsmouth
Portsmouth logs 65.0 inches of snow most years, per federal climate normals.
Sliding snow off a Portsmouth metal roof can be a genuine hazard to whatever's below the eaves, from a walkway to a parked car.
Snow guards are the standard answer, and they're worth planning into a Portsmouth metal roof from the installation quote, not after the first slide.
