Anson County, NC Roof Snow Load - 10 psf
What ASCE 7 says about snow load in Anson County
That's Anson 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 Anson County are actually governed by ASCE 7's §7.3.4 minimum of 10 psf, not the 7 psf the ground-load formula alone would produce.
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. This is a modest add-on to standard roof loading - ordinary residential construction carries it without extra bracing.

Read this before you rely on it
