Green Lake County, WI Roof Snow Load - 24.5 psf
Green Lake County, WI: your roof's ASCE 7 snow number, in plain English
Green Lake County's roofs are built to hold 24.5 psf of snow, the ASCE 7-22 figure a permit reviewer checks first.
In depth, not weight: that's roughly 53.9 inches of fresh, light snow, 19.6 inches of old, settled snow, or as little as 4.9 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 meaningful design load. Most homes built to modern code handle it, but additions, carports, and flat-roofed sections are worth a second look.

Before you rely on Green Lake County's number
Treat the Green Lake 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.
