Beadle County, SD Roof Snow Load - 28 psf
What ASCE 7 says about snow load in Beadle County
That's Beadle 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 61.6 in. of fresh powder, 22.4 in. once it settles and packs down, or just 5.6 in. if it's turned to ice. Modern-code homes carry a load like this without issue; an older addition, a carport, or any flat-roofed section is where it is worth checking first.
