Martin County, FL Roof Snow Load - 0 psf
Martin County, FL: your roof's ASCE 7 snow number, in plain English
Martin County's roofs are built to hold 0 psf of snow, the ASCE 7-22 figure a permit reviewer checks first.
In depth, not weight: that's roughly 0 inches of fresh, light snow, 0 inches of old, settled snow, or as little as 0 inches of solid ice - snow that heavy is rare here but ice from a freeze-thaw cycle adds up far faster than the depth suggests. Snow load is not a factor in roof design here at all; the ground snow load figure maps to zero.

Before you rely on Martin County's number
Treat the Martin County figure as a starting point, not a final answer: it assumes standard occupancy, a heated structure and a moderately sheltered site, per ASCE 7-22's own defaults. Exposed terrain, an unheated building or a steeper roof all shift the real number.
For a real application, skip the county number and go straight to the ASCE 7 Hazard Tool - enter your coordinates and it returns a site-specific figure a plan reviewer will recognize. Details: the calculation guide.
