Hancock County, IN Roof Snow Load - 20 psf
How much snow is too much for a roof in Hancock County, IN?
20 psf: that's what ASCE 7-22 requires a typical heated home's roof in Hancock County to carry. §7.3.4's low-slope minimum of 20 psf is what actually governs on a flat or low-pitch roof here - higher than the 14 psf the base ground-load formula gives.
Picture it, not just weigh it: 44 in. if it's fresh powder, 16 in. once it settles, or a mere 4 in. if it's ice. 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.

How Hancock County compares
20 psf ranks #666 of 2,758 US counties with a mapped snow load (top 24%) - and #13 of 89 in Indiana. That's 0.7 psf above Indiana's own county-average design load of 19.3 psf.
Population 88,810 (FIPS 18059), roughly 39.8225°N 85.7732°W. The 20 psf ground snow load ASCE 7-22 maps here becomes 20 psf once the code's own design factors are applied.

What this Hancock 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.
Hancock 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. See the methodology guide.
