Florence County, WI Roof Snow Load - 42 psf
What ASCE 7 says about snow load in Florence County
That's Florence County's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from.
Converted to something you can actually eyeball on a roof: about 92.4 in. of fresh powder, 33.6 in. once it settles and packs down, or just 8.4 in. if it's turned to ice. A load this size is a serious structural matter; pre-modern-code homes and low-slope or flat-roofed sections are the ones most worth an inspection.
