Noble County, OK Roof Snow Load - 10 psf
What ASCE 7 says about snow load in Noble County
That's Noble County's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from. ASCE 7's low-slope-roof minimum (§7.3.4) raises the governing figure to 10 psf - higher than the 7 psf the ground-load formula alone would give, and the code says use the larger one.
Converted to something you can actually eyeball on a roof: about 22 in. of fresh powder, 8 in. once it settles and packs down, or just 2 in. if it's turned to ice. A modest addition to standard roof loading. Ordinary residential construction handles this without extra bracing.
