Grant Parish, LA Roof Snow Load - 5 psf
How much snow is too much for a roof in Grant Parish, LA?
5 psf: that's what ASCE 7-22 requires a typical heated home's roof in Grant Parish to carry. Flat and low-pitch roofs in Grant Parish are actually governed by ASCE 7's §7.3.4 minimum of 5 psf, not the 3.5 psf the ground-load formula alone would produce.
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. A modest addition to standard roof loading. Ordinary residential construction handles this without extra bracing.

What this Grant 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.
Grant 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. Details: the calculation guide.
