Wright County, MN Roof Snow Load - 35 psf
How much snow is too much for a roof in Wright County, MN?
35 psf: that's what ASCE 7-22 requires a typical heated home's roof in Wright 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. This is a serious structural load - older homes built before modern snow-load provisions, or ones with low-slope or flat roof sections, are worth having checked.

What this Wright 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.
Wright 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. Details: the calculation guide.
