Webb County, TX Roof Snow Load - 0 psf
What ASCE 7 says about snow load in Webb County
That's Webb County's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from.
Converted to something you can actually eyeball on a roof: about 0 in. of fresh powder, 0 in. once it settles and packs down, or just 0 in. if it's turned to ice. This county’s ground snow load maps to zero - snow load is not a driver of roof design here.

How much it actually snows in Webb County
Most winters bring Webb County roughly 0 in. of snow - NOAA's normal at LOS ANGELES 4 WSW, TX US, 50.3 mi off. 50.3 mi is a real gap between Webb County and its nearest reporting station, so local snowfall can diverge from this figure, especially near elevation changes. (fresh vs. packed vs. ice explains why.)
Read this before you rely on it
Webb 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.
