Childress County, TX Roof Snow Load - 10 psf
Childress County, TX roof snow load, translated
A typical heated home in Childress County is designed to carry 10 pounds per square foot of snow on its roof, per ASCE 7-22. Flat and low-pitch roofs in Childress County are actually governed by ASCE 7's §7.3.4 minimum of 10 psf, not the 7 psf the ground-load formula alone would produce.
On a roof that means 22 in. of fresh snow, 8 in. once it packs down, or 2 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.

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.
