Moore County, TX Roof Snow Load - 15 psf

How much snow is too much for a roof in Moore County, TX?

Moderate
15 psf

15 psf: that's what ASCE 7-22 requires a typical heated home's roof in Moore County to carry. Flat and low-pitch roofs in Moore County are actually governed by ASCE 7's §7.3.4 minimum of 15 psf, not the 10.5 psf the ground-load formula alone would produce.

Picture it, not just weigh it: 33 in. if it's fresh powder, 12 in. once it settles, or a mere 3 in. if it's ice. A meaningful design load. Most homes built to modern code handle it, but additions, carports, and flat-roofed sections are worth a second look.

How Moore County compares

15 psf ranks #1,455 of 2,758 US counties with a mapped snow load (top 53%) - and #9 of 254 in Texas. That's 9.6 psf above Texas's own county-average design load of 5.4 psf.

Population 21,872 (FIPS 48341), roughly 35.8357°N 101.8905°W. The 15 psf ground snow load ASCE 7-22 maps here becomes 15 psf once the code's own design factors are applied.

Typical snowfall in Moore County, TX

NOAA's 30-year normal for Moore County: 12.7 in. of snow a year, from the CONLEN, TX US station. That station is far enough away (33.8 mi) that local snowfall - especially at a different elevation or near a lake - can run noticeably higher or lower than this figure. (fresh vs. packed vs. ice explains why.)

What this Moore County figure assumes

This is a county-level reference figure for a typical heated home built to Risk Category II (ordinary residential), on a partially exposed lot - the assumptions ASCE 7-22 itself treats as the default case. A steeper roof, a fully exposed hilltop lot, an unheated structure, or a higher risk category all change the actual number.

Moore County's permit office wants an address-specific figure, not this county average - the ASCE 7 Hazard Tool is free, takes under a minute, and outputs a PDF most reviewers accept. Details: the calculation guide.
