Cayuga County, NY Roof Snow Load - 28 psf
Cayuga County, NY roof snow load, translated
A typical heated home in Cayuga County is designed to carry 28 pounds per square foot of snow on its roof, per ASCE 7-22.
On a roof that means 61.6 in. of fresh snow, 22.4 in. once it packs down, or 5.6 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.
A building permit needs the number at your exact address, not the county average - the free ASCE 7 Hazard Tool returns that from your coordinates in about a minute and produces a PDF a plan reviewer will accept. See the methodology guide.
