Deuel County, SD Roof Snow Load - 35 psf

How much snow is too much for a roof in Deuel County, SD?

Picture it, not just weigh it: 77 in. if it's fresh powder, 28 in. once it settles, or a mere 7 in. if it's ice. A load this size is a serious structural matter; pre-modern-code homes and low-slope or flat-roofed sections are the ones most worth an inspection.

What this Deuel 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.

Deuel 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. (How this figure is calculated.)
