Lake County, MN Roof Snow Load - 42 psf
What ASCE 7 says about snow load in Lake County
That's Lake 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 serious structural load. Homes built before modern snow-load provisions, or with low-slope/flat roof sections, are the ones most worth having checked.

Read this before you rely on it
Lake County's number above is ASCE 7-22's default case, not a custom calculation: ordinary residential occupancy, heated, sited on ground that's neither fully sheltered nor fully exposed. Any one of those changing - pitch, exposure, heating, occupancy - moves the real figure.
