San Jacinto County, TX Roof Snow Load - 5 psf
San Jacinto County, TX: your roof's ASCE 7 snow number, in plain English
San Jacinto County's roofs are built to hold 5 psf of snow, the ASCE 7-22 figure a permit reviewer checks first. 3.5 psf is what the ground-load formula alone gives; San Jacinto 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.
In depth, not weight: that's roughly 11 inches of fresh, light snow, 4 inches of old, settled snow, or as little as 1 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. Standard residential construction handles a load this size without extra bracing; it is a modest addition on top of ordinary roof loading.

Before you rely on San Jacinto County's number
Treat the San Jacinto 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. (How this figure is calculated.)
