Greeley County, KS Roof Snow Load - 10 psf
Greeley County, KS roof snow load, translated
A typical heated home in Greeley County is designed to carry 10 pounds per square foot of snow on its roof, per ASCE 7-22. Flat and low-pitch roofs in Greeley County are actually governed by ASCE 7's §7.3.4 minimum of 10 psf, not the 7 psf the ground-load formula alone would produce.
On a roof that means 22 in. of fresh snow, 8 in. once it packs down, or 2 in. of solid ice - three very different piles for the same load. A modest addition to standard roof loading. Ordinary residential construction handles this without extra bracing.

The figure above assumes the case ASCE 7-22 treats as typical: a heated, ordinary-occupancy home on a partially exposed site. Change any of those - exposure, heating, roof pitch, occupancy category - and the real design number moves.
