Ogemaw County, MI Roof Snow Load - 35 psf
How much snow is too much for a roof in Ogemaw County, MI?
35 psf: that's what ASCE 7-22 requires a typical heated home's roof in Ogemaw County to carry.
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 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 Ogemaw 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.
Ogemaw 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.)
