Van Zandt County, TX Roof Snow Load - 5 psf
Van Zandt County, TX roof snow load, translated
A typical heated home in Van Zandt 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 Van Zandt 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. A modest addition to standard roof loading. Ordinary residential construction handles this without extra bracing.

Van Zandt County: average annual snowfall
Van Zandt County sees about 0.1 in. of snow most winters, per the TERRELL, TX US station's 1991-2020 NOAA normal. 30.7 mi is a real gap between Van Zandt County and its nearest reporting station, so local snowfall can diverge from this figure, especially near elevation changes.

The figure above assumes the case ASCE 7-22 treats as typical: a heated, ordinary-occupancy home on a partially exposed site. Change any of those - exposure, heating, roof pitch, occupancy category - and the real design number moves.
