Henry County, KY Roof Snow Load - 15 psf

What ASCE 7 says about snow load in Henry County

Moderate
15 psf

That's Henry County's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from. 10.5 psf is what the ground-load formula alone gives; Henry County's 15 psf low-slope minimum (§7.3.4) beats it, so that figure is the one that governs on flat and low-pitch roofs.

Converted to something you can actually eyeball on a roof: about 33 in. of fresh powder, 12 in. once it settles and packs down, or just 3 in. if it's turned to ice. This is a meaningful design load - most modern-code homes handle it fine, though an addition, a carport or a flat-roofed section can be a weak spot.

Read this before you rely on it
