Scotland County, NC Roof Snow Load - 10 psf
Scotland County, NC roof snow load, translated
A typical heated home in Scotland County is designed to carry 10 pounds per square foot of snow on its roof, per ASCE 7-22. The physics-based figure alone would be 7 psf, but ASCE 7's own low-slope minimum (§7.3.4) sets a floor of 10 psf for flat and low-pitch roofs here, which is the number that actually governs.
On a roof that means 22 in. of fresh snow, 8 in. once it packs down, or 2 in. of solid ice - three very different piles for the same load. This is a modest add-on to standard roof loading - ordinary residential construction carries it without extra bracing.

Where Scotland County ranks
#79 of 100 North Carolina counties by design load, top 66% of 2,758 nationally - that's Scotland County's spot. That's 2.9 psf below North Carolina's own county-average design load of 12.9 psf.
FIPS 37165, population 33,898, centered near 34.84°N 79.4773°W. ASCE 7's underlying ground snow load here is 10 psf before the code's exposure and importance factors bring it to the 10 psf design figure above.
Scotland 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.
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. (How this figure is calculated.)
