Yalobusha County, MS Roof Snow Load - 10 psf

How much snow is too much for a roof in Yalobusha County, MS?

Light
10 psf

10 psf: that's what ASCE 7-22 requires a typical heated home's roof in Yalobusha County to carry. 7 psf is what the ground-load formula alone gives; Yalobusha 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. Standard residential construction handles a load this size without extra bracing; it is a modest addition on top of ordinary roof loading.

What this Yalobusha 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.

Yalobusha County'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.)
