Burke County, ND Roof Snow Load - 24.5 psf

Burke County, ND: your roof's ASCE 7 snow number, in plain English

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.

Burke County's snowfall, most winters

43.7 in. a year: that's Burke County's NOAA 1991-2020 snowfall normal, measured at TIOGA 1E, ND US (32.4 mi away). That station is far enough away (32.4 mi) that local snowfall - especially at a different elevation or near a lake - can run noticeably higher or lower than this figure. See the density guide.

Before you rely on Burke County's number

Treat the Burke 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. Details: the calculation guide.
