Boyd County, NE Roof Snow Load - 24.5 psf
Boyd County, NE roof snow load, translated
A typical heated home in Boyd County is designed to carry 24.5 pounds per square foot of snow on its roof, per ASCE 7-22.
On a roof that means 53.9 in. of fresh snow, 19.6 in. once it packs down, or 4.9 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.
