Crosby County, TX Roof Snow Load - 10 psf
How much snow is too much for a roof in Crosby County, TX?
10 psf: that's what ASCE 7-22 requires a typical heated home's roof in Crosby County to carry. 7 psf is what the ground-load formula alone gives; Crosby County's 10 psf low-slope minimum (§7.3.4) beats it, so that figure is the one that governs on flat and low-pitch roofs.
Picture it, not just weigh it: 22 in. if it's fresh powder, 8 in. once it settles, or a mere 2 in. if it's ice. A modest addition to standard roof loading. Ordinary residential construction handles this without extra bracing.

What this Crosby County figure assumes
This is a county-level reference figure for a typical heated home built to Risk Category II (ordinary residential), on a partially exposed lot - the assumptions ASCE 7-22 itself treats as the default case. A steeper roof, a fully exposed hilltop lot, an unheated structure, or a higher risk category all change the actual number.
