King and Queen County, VA Roof Snow Load - 20 psf
King and Queen County, VA: your roof's ASCE 7 snow number, in plain English
King and Queen County's roofs are built to hold 20 psf of snow, the ASCE 7-22 figure a permit reviewer checks first. 14 psf is what the ground-load formula alone gives; King and Queen County's 20 psf low-slope minimum (§7.3.4) beats it, so that figure is the one that governs on flat and low-pitch roofs.
In depth, not weight: that's roughly 44 inches of fresh, light snow, 16 inches of old, settled snow, or as little as 4 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. This is a meaningful design load - most modern-code homes handle it fine, though an addition, a carport or a flat-roofed section can be a weak spot.

King and Queen County's snowfall, most winters
8.5 in. a year: that's King and Queen County's NOAA 1991-2020 snowfall normal, measured at N, VA US (32.1 mi away). 32.1 mi is a real gap between King and Queen County and its nearest reporting station, so local snowfall can diverge from this figure, especially near elevation changes. See the density guide.
Before you rely on King and Queen County's number
Treat the King and Queen 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.
