Oldham County, TX Roof Snow Load - 10 psf
Oldham County, TX: your roof's ASCE 7 snow number, in plain English
Oldham County's roofs are built to hold 10 psf of snow, the ASCE 7-22 figure a permit reviewer checks first. 7 psf is what the ground-load formula alone gives; Oldham County's 10 psf low-slope minimum (§7.3.4) beats it, so that figure is the one that governs on flat and low-pitch roofs.
In depth, not weight: that's roughly 22 inches of fresh, light snow, 8 inches of old, settled snow, or as little as 2 inches of solid ice - snow that heavy is rare here but ice from a freeze-thaw cycle adds up far faster than the depth suggests. This is a modest add-on to standard roof loading - ordinary residential construction carries it without extra bracing.

Before you rely on Oldham County's number
Treat the Oldham County figure as a starting point, not a final answer: it assumes standard occupancy, a heated structure and a moderately sheltered site, per ASCE 7-22's own defaults. Exposed terrain, an unheated building or a steeper roof all shift the real number.
For a real application, skip the county number and go straight to the ASCE 7 Hazard Tool - enter your coordinates and it returns a site-specific figure a plan reviewer will recognize. Details: the calculation guide.
