Lincoln County, SD Roof Snow Load - 28 psf
How much snow is too much for a roof in Lincoln County, SD?
28 psf: that's what ASCE 7-22 requires a typical heated home's roof in Lincoln County to carry.
Picture it, not just weigh it: 61.6 in. if it's fresh powder, 22.4 in. once it settles, or a mere 5.6 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.

What this Lincoln 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.
Lincoln 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.
