Reynolds County, MO Roof Snow Load - 15 psf
What ASCE 7 says about snow load in Reynolds County
That's Reynolds County's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from. 10.5 psf is what the ground-load formula alone gives; Reynolds County's 15 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 33 in. of fresh powder, 12 in. once it settles and packs down, or just 3 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.

How much it actually snows in Reynolds County
Most winters bring Reynolds County roughly 6 in. of snow - NOAA's normal at EMINENCE 1 N, MO US, 25.8 mi off. 25.8 mi is a real gap between Reynolds County and its nearest reporting station, so local snowfall can diverge from this figure, especially near elevation changes. (fresh vs. packed vs. ice explains why.)
Read this before you rely on it
Reynolds 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.
