Greene County, GA Roof Snow Load - 5 psf
How much snow is too much for a roof in Greene County, GA?
5 psf: that's what ASCE 7-22 requires a typical heated home's roof in Greene County to carry. 3.5 psf is what the ground-load formula alone gives; Greene County's 5 psf low-slope minimum (§7.3.4) beats it, so that figure is the one that governs on flat and low-pitch roofs.
Picture it, not just weigh it: 11 in. if it's fresh powder, 4 in. once it settles, or a mere 1 in. if it's ice. Standard residential construction handles a load this size without extra bracing; it is a modest addition on top of ordinary roof loading.

How Greene County compares
5 psf ranks #2,286 of 2,758 US counties with a mapped snow load (top 83%) - and #69 of 159 in Georgia. That's 1.4 psf above Georgia's own county-average design load of 3.6 psf.
Population 21,091 (FIPS 13133), roughly 33.5767°N 83.1666°W. The 5 psf ground snow load ASCE 7-22 maps here becomes 5 psf once the code's own design factors are applied.

What this Greene 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.
Greene 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.
