Burnett County, WI Roof Snow Load - 42 psf
How much snow is too much for a roof in Burnett County, WI?
42 psf: that's what ASCE 7-22 requires a typical heated home's roof in Burnett 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. 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 Burnett 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.
