Henderson County, KY Roof Snow Load - 15 psf
What ASCE 7 says about snow load in Henderson County
That's Henderson 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; Henderson 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. A meaningful design load. Most homes built to modern code handle it, but additions, carports, and flat-roofed sections are worth a second look.
