Red River Parish, LA Roof Snow Load - 5 psf
What ASCE 7 says about snow load in Red River Parish
That's Red River Parish's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from. 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.
Converted to something you can actually eyeball on a roof: about 11 in. of fresh powder, 4 in. once it settles and packs down, or just 1 in. if it's turned to ice. This is a modest add-on to standard roof loading - ordinary residential construction carries it without extra bracing.

Read this before you rely on it
Red River Parish's number above is ASCE 7-22's default case, not a custom calculation: ordinary residential occupancy, heated, sited on ground that's neither fully sheltered nor fully exposed. Any one of those changing - pitch, exposure, heating, occupancy - moves the real figure.
