Claiborne Parish, LA Roof Snow Load - 5 psf
Claiborne Parish, LA: your roof's ASCE 7 snow number, in plain English
Claiborne Parish's roofs are built to hold 5 psf of snow, the ASCE 7-22 figure a permit reviewer checks first. 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.
In depth, not weight: that's roughly 11 inches of fresh, light snow, 4 inches of old, settled snow, or as little as 1 inches of solid ice - snow that heavy is rare here but ice from a freeze-thaw cycle adds up far faster than the depth suggests. Standard residential construction handles a load this size without extra bracing; it is a modest addition on top of ordinary roof loading.

Before you rely on Claiborne Parish's number
Treat the Claiborne Parish figure as a starting point, not a final answer: it assumes standard occupancy, a heated structure and a moderately sheltered site, per ASCE 7-22's own defaults. Exposed terrain, an unheated building or a steeper roof all shift the real number.
For a real application, skip the county number and go straight to the ASCE 7 Hazard Tool - enter your coordinates and it returns a site-specific figure a plan reviewer will recognize. (How this figure is calculated.)
