Delta County, TX Roof Snow Load - 5 psf
What ASCE 7 says about snow load in Delta County
That's Delta County's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from. The physics-based figure alone would be 3.5 psf, but ASCE 7's own low-slope minimum (§7.3.4) sets a floor of 5 psf for flat and low-pitch roofs here, which is the number that actually governs.
Converted to something you can actually eyeball on a roof: about 11 in. of fresh powder, 4 in. once it settles and packs down, or just 1 in. if it's turned to ice. Standard residential construction handles a load this size without extra bracing; it is a modest addition on top of ordinary roof loading.

Read this before you rely on it
Delta County's number above is ASCE 7-22's default case, not a custom calculation: ordinary residential occupancy, heated, sited on ground that's neither fully sheltered nor fully exposed. Any one of those changing - pitch, exposure, heating, occupancy - moves the real figure.
