Texas County, MO Roof Snow Load - 20 psf
Texas County, MO roof snow load, translated
A typical heated home in Texas County is designed to carry 20 pounds per square foot of snow on its roof, per ASCE 7-22. Flat and low-pitch roofs in Texas County are actually governed by ASCE 7's §7.3.4 minimum of 20 psf, not the 14 psf the ground-load formula alone would produce.
On a roof that means 44 in. of fresh snow, 16 in. once it packs down, or 4 in. of solid ice - three very different piles for the same load. 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.

Where Texas County ranks
#27 of 115 Missouri counties by design load, top 33% of 2,758 nationally - that's Texas County's spot. Missouri counties average 18.6 psf; Texas County runs 1.4 psf higher than that.
FIPS 29215, population 25,715, centered near 37.3143°N 91.9645°W. ASCE 7's underlying ground snow load here is 20 psf before the code's exposure and importance factors bring it to the 20 psf design figure above.
Texas County: average annual snowfall

The figure above assumes the case ASCE 7-22 treats as typical: a heated, ordinary-occupancy home on a partially exposed site. Change any of those - exposure, heating, roof pitch, occupancy category - and the real design number moves.
