Boone County, NE Roof Snow Load - 20 psf
How much snow is too much for a roof in Boone County, NE?
20 psf: that's what ASCE 7-22 requires a typical heated home's roof in Boone County to carry. 17.5 psf is what the ground-load formula alone gives; Boone County's 20 psf low-slope minimum (§7.3.4) beats it, so that figure is the one that governs on flat and low-pitch roofs.
Picture it, not just weigh it: 44 in. if it's fresh powder, 16 in. once it settles, or a mere 4 in. if it's ice. A meaningful design load. Most homes built to modern code handle it, but additions, carports, and flat-roofed sections are worth a second look.

How Boone County compares
20 psf ranks #1,210 of 2,758 US counties with a mapped snow load (top 44%) - and #55 of 93 in Nebraska. Nebraska counties average 20.2 psf; Boone County runs 0.2 psf lower than that.
Population 5,354 (FIPS 31011), roughly 41.7039°N 98.0705°W. The 25 psf ground snow load ASCE 7-22 maps here becomes 20 psf once the code's own design factors are applied.
Typical snowfall in Boone County, NE
NOAA's 30-year normal for Boone County: 26.6 in. of snow a year, from the ALBION, NE US station. (fresh vs. packed vs. ice explains why.)
What this Boone County figure assumes
This is a county-level reference figure for a typical heated home built to Risk Category II (ordinary residential), on a partially exposed lot - the assumptions ASCE 7-22 itself treats as the default case. A steeper roof, a fully exposed hilltop lot, an unheated structure, or a higher risk category all change the actual number.
Boone County's permit office wants an address-specific figure, not this county average - the ASCE 7 Hazard Tool is free, takes under a minute, and outputs a PDF most reviewers accept. See the methodology guide.
