Lincoln County, WI Roof Snow Load - 42 psf
Lincoln County, WI: your roof's ASCE 7 snow number, in plain English
Lincoln County's roofs are built to hold 42 psf of snow, the ASCE 7-22 figure a permit reviewer checks first.
In depth, not weight: that's roughly 92.4 inches of fresh, light snow, 33.6 inches of old, settled snow, or as little as 8.4 inches of solid ice - snow that heavy is rare here but ice from a freeze-thaw cycle adds up far faster than the depth suggests. 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.

Before you rely on Lincoln County's number
Treat the Lincoln County figure as a starting point, not a final answer: it assumes standard occupancy, a heated structure and a moderately sheltered site, per ASCE 7-22's own defaults. Exposed terrain, an unheated building or a steeper roof all shift the real number.
For a real application, skip the county number and go straight to the ASCE 7 Hazard Tool - enter your coordinates and it returns a site-specific figure a plan reviewer will recognize. (How this figure is calculated.)
