Baca County, CO Roof Snow Load - 15 psf
Baca County, CO roof snow load, translated
A typical heated home in Baca County is designed to carry 15 pounds per square foot of snow on its roof, per ASCE 7-22. Flat and low-pitch roofs in Baca County are actually governed by ASCE 7's §7.3.4 minimum of 15 psf, not the 10.5 psf the ground-load formula alone would produce.
On a roof that means 33 in. of fresh snow, 12 in. once it packs down, or 3 in. of solid ice - three very different piles for the same load. Modern-code homes carry a load like this without issue; an older addition, a carport, or any flat-roofed section is where it is worth checking first.

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.
