Livingston County, KY Roof Snow Load - 15 psf

Livingston County, KY roof snow load, translated

Moderate
15 psf

A typical heated home in Livingston County is designed to carry 15 pounds per square foot of snow on its roof, per ASCE 7-22. 10.5 psf is what the ground-load formula alone gives; Livingston 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.

On a roof that means 33 in. of fresh snow, 12 in. once it packs down, or 3 in. of solid ice - three very different piles for the same load. A meaningful design load. Most homes built to modern code handle it, but additions, carports, and flat-roofed sections are worth a second look.

Where Livingston County ranks

#108 of 120 Kentucky counties by design load, top 57% of 2,758 nationally - that's Livingston County's spot. That's 0.7 psf below Kentucky's own county-average design load of 15.7 psf.

FIPS 21139, population 8,815, centered near 37.2095°N 88.3634°W. ASCE 7's underlying ground snow load here is 15 psf before the code's exposure and importance factors bring it to the 15 psf design figure above.

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.

A building permit needs the number at your exact address, not the county average - the free ASCE 7 Hazard Tool returns that from your coordinates in about a minute and produces a PDF a plan reviewer will accept. See the methodology guide.
