Caldwell Parish, LA Roof Snow Load - 5 psf
How much snow is too much for a roof in Caldwell Parish, LA?
5 psf: that's what ASCE 7-22 requires a typical heated home's roof in Caldwell Parish to carry. ASCE 7's low-slope-roof minimum (§7.3.4) raises the governing figure to 5 psf - higher than the 3.5 psf the ground-load formula alone would give, and the code says use the larger one.
Picture it, not just weigh it: 11 in. if it's fresh powder, 4 in. once it settles, or a mere 1 in. if it's ice. Standard residential construction handles a load this size without extra bracing; it is a modest addition on top of ordinary roof loading.

What this Caldwell Parish 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.
Caldwell Parish's permit office wants an address-specific figure, not this county average - the ASCE 7 Hazard Tool is free, takes under a minute, and outputs a PDF most reviewers accept. (How this figure is calculated.)
