Gonzales County, TX Roof Snow Load - 5 psf
Gonzales County, TX roof snow load, translated
A typical heated home in Gonzales County is designed to carry 5 pounds per square foot of snow on its roof, per ASCE 7-22. Flat and low-pitch roofs in Gonzales 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.
On a roof that means 11 in. of fresh snow, 4 in. once it packs down, or 1 in. of solid ice - three very different piles for the same load. This is a modest add-on to standard roof loading - ordinary residential construction carries it without extra bracing.
