Union County, FL Roof Snow Load - 0 psf
Union County, FL roof snow load, translated
A typical heated home in Union County is designed to carry 0 pounds per square foot of snow on its roof, per ASCE 7-22.
On a roof that means 0 in. of fresh snow, 0 in. once it packs down, or 0 in. of solid ice - three very different piles for the same load. Snow load is not a factor in roof design here at all; the ground snow load figure maps to zero.

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. Details: the calculation guide.
