Fannin County, GA Roof Snow Load - 10 psf
How much snow is too much for a roof in Fannin County, GA?
10 psf: that's what ASCE 7-22 requires a typical heated home's roof in Fannin County to carry. Flat and low-pitch roofs in Fannin 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.
Picture it, not just weigh it: 22 in. if it's fresh powder, 8 in. once it settles, or a mere 2 in. if it's ice. This is a modest add-on to standard roof loading - ordinary residential construction carries it without extra bracing.

What this Fannin County figure assumes
This is a county-level reference figure for a typical heated home built to Risk Category II (ordinary residential), on a partially exposed lot - the assumptions ASCE 7-22 itself treats as the default case. A steeper roof, a fully exposed hilltop lot, an unheated structure, or a higher risk category all change the actual number.
Fannin County's permit office wants an address-specific figure, not this county average - the ASCE 7 Hazard Tool is free, takes under a minute, and outputs a PDF most reviewers accept. Details: the calculation guide.
