Monroe County, NY Roof Snow Load - 28 psf

Monroe County, NY: your roof's ASCE 7 snow number, in plain English

In depth, not weight: that's roughly 61.6 inches of fresh, light snow, 22.4 inches of old, settled snow, or as little as 5.6 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. 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.

Before you rely on Monroe County's number

Treat the Monroe 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.
