Lee County, TX Roof Snow Load - 5 psf
What ASCE 7 says about snow load in Lee County
That's Lee County's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from. 3.5 psf is what the ground-load formula alone gives; Lee County's 5 psf low-slope minimum (§7.3.4) beats it, so that figure is the one that governs on flat and low-pitch roofs.
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. This is a modest add-on to standard roof loading - ordinary residential construction carries it without extra bracing.

Read this before you rely on it
