Atlantic County, NJ Roof Snow Load - 20 psf
What ASCE 7 says about snow load in Atlantic County
That's Atlantic County's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from. 14 psf is what the ground-load formula alone gives; Atlantic 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.
Converted to something you can actually eyeball on a roof: about 44 in. of fresh powder, 16 in. once it settles and packs down, or just 4 in. if it's turned to ice. 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.

Read this before you rely on it
Atlantic County's number above is ASCE 7-22's default case, not a custom calculation: ordinary residential occupancy, heated, sited on ground that's neither fully sheltered nor fully exposed. Any one of those changing - pitch, exposure, heating, occupancy - moves the real figure.
