Pepin County, WI Roof Snow Load - 35 psf
What ASCE 7 says about snow load in Pepin County
That's Pepin 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 77 in. of fresh powder, 28 in. once it settles and packs down, or just 7 in. if it's turned to ice. A serious structural load. Homes built before modern snow-load provisions, or with low-slope/flat roof sections, are the ones most worth having checked.
