Divide County, ND Roof Snow Load - 24.5 psf
Divide County, ND roof snow load, translated
A typical heated home in Divide County is designed to carry 24.5 pounds per square foot of snow on its roof, per ASCE 7-22.
On a roof that means 53.9 in. of fresh snow, 19.6 in. once it packs down, or 4.9 in. of solid ice - three very different piles for the same load. 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.

The figure above assumes the case ASCE 7-22 treats as typical: a heated, ordinary-occupancy home on a partially exposed site. Change any of those - exposure, heating, roof pitch, occupancy category - and the real design number moves.
A building permit needs the number at your exact address, not the county average - the free ASCE 7 Hazard Tool returns that from your coordinates in about a minute and produces a PDF a plan reviewer will accept. Details: the calculation guide.
