Coke County, TX Roof Snow Load - 5 psf
How much snow is too much for a roof in Coke County, TX?
5 psf: that's what ASCE 7-22 requires a typical heated home's roof in Coke County to carry. The physics-based figure alone would be 3.5 psf, but ASCE 7's own low-slope minimum (§7.3.4) sets a floor of 5 psf for flat and low-pitch roofs here, which is the number that actually governs.
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. This is a modest add-on to standard roof loading - ordinary residential construction carries it without extra bracing.

How Coke County compares
5 psf ranks #2,445 of 2,758 US counties with a mapped snow load (top 89%) - and #188 of 254 in Texas. That's 0.4 psf below Texas's own county-average design load of 5.4 psf.
Population 3,396 (FIPS 48081), roughly 31.8771°N 100.6352°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 Coke 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.
Coke 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. (How this figure is calculated.)
