Bryan County, OK Roof Snow Load - 5 psf
What ASCE 7 says about snow load in Bryan County
That's Bryan County's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from. §7.3.4's low-slope minimum of 5 psf is what actually governs on a flat or low-pitch roof here - higher than the 3.5 psf the base ground-load formula gives.
Converted to something you can actually eyeball on a roof: about 11 in. of fresh powder, 4 in. once it settles and packs down, or just 1 in. if it's turned to ice. Standard residential construction handles a load this size without extra bracing; it is a modest addition on top of ordinary roof loading.
