Parker County, TX Roof Snow Load - 5 psf
Parker County, TX roof snow load, translated
A typical heated home in Parker 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 Parker 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. Standard residential construction handles a load this size without extra bracing; it is a modest addition on top of ordinary roof loading.

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.
