Cheboygan County, MI Roof Snow Load - 42 psf
How much snow is too much for a roof in Cheboygan County, MI?
42 psf: that's what ASCE 7-22 requires a typical heated home's roof in Cheboygan County to carry.
Picture it, not just weigh it: 92.4 in. if it's fresh powder, 33.6 in. once it settles, or a mere 8.4 in. if it's ice. A serious structural load. Homes built before modern snow-load provisions, or with low-slope/flat roof sections, are the ones most worth having checked.

What this Cheboygan 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.
