East Carroll Parish, LA Roof Snow Load - 5 psf
East Carroll Parish, LA roof snow load, translated
A typical heated home in East Carroll Parish is designed to carry 5 pounds per square foot of snow on its roof, per ASCE 7-22. 3.5 psf is what the ground-load formula alone gives; East Carroll Parish'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.
On a roof that means 11 in. of fresh snow, 4 in. once it packs down, or 1 in. of solid ice - three very different piles for the same load. A modest addition to standard roof loading. Ordinary residential construction handles this without extra bracing.

The figure above assumes the case ASCE 7-22 treats as typical: a heated, ordinary-occupancy home on a partially exposed site. Change any of those - exposure, heating, roof pitch, occupancy category - and the real design number moves.
