Burleigh County, ND Roof Snow Load - 24.5 psf
What ASCE 7 says about snow load in Burleigh County
That's Burleigh County's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from.
Converted to something you can actually eyeball on a roof: about 53.9 in. of fresh powder, 19.6 in. once it settles and packs down, or just 4.9 in. if it's turned to 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.
