Kewaunee County, WI Roof Snow Load - 28 psf
Kewaunee County, WI: your roof's ASCE 7 snow number, in plain English
Kewaunee County's roofs are built to hold 28 psf of snow, the ASCE 7-22 figure a permit reviewer checks first.
In depth, not weight: that's roughly 61.6 inches of fresh, light snow, 22.4 inches of old, settled snow, or as little as 5.6 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. This is a meaningful design load - most modern-code homes handle it fine, though an addition, a carport or a flat-roofed section can be a weak spot.

Before you rely on Kewaunee County's number
Treat the Kewaunee 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. See the methodology guide.
