Liberty County, TX Roof Snow Load - 5 psf

Liberty County, TX: your roof's ASCE 7 snow number, in plain English

Light
5 psf

Liberty County's roofs are built to hold 5 psf of snow, the ASCE 7-22 figure a permit reviewer checks first. Flat and low-pitch roofs in Liberty County are actually governed by ASCE 7's §7.3.4 minimum of 5 psf, not the 3.5 psf the ground-load formula alone would produce.

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. A modest addition to standard roof loading. Ordinary residential construction handles this without extra bracing.

Before you rely on Liberty County's number

Treat the Liberty 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.)
