Duval County, TX Roof Snow Load - 0 psf
What ASCE 7 says about snow load in Duval County
That's Duval 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.

Read this before you rely on it
