Butler County, KS Roof Snow Load - 15 psf

What ASCE 7 says about snow load in Butler County

Moderate
15 psf

That's Butler County's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from. The physics-based figure alone would be 10.5 psf, but ASCE 7's own low-slope minimum (§7.3.4) sets a floor of 15 psf for flat and low-pitch roofs here, which is the number that actually governs.

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.

Read this before you rely on it
