Clayton County, GA Roof Snow Load - 5 psf
What ASCE 7 says about snow load in Clayton County
That's Clayton County's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from. Flat and low-pitch roofs in Clayton County are actually governed by ASCE 7's §7.3.4 minimum of 5 psf, not the 3.5 psf the ground-load formula alone would produce.
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.

Read this before you rely on it
