Rogers County, OK Roof Snow Load - 10 psf
How much snow is too much for a roof in Rogers County, OK?
10 psf: that's what ASCE 7-22 requires a typical heated home's roof in Rogers County to carry. §7.3.4's low-slope minimum of 10 psf is what actually governs on a flat or low-pitch roof here - higher than the 7 psf the base ground-load formula gives.
Picture it, not just weigh it: 22 in. if it's fresh powder, 8 in. once it settles, or a mere 2 in. if it's ice. Standard residential construction handles a load this size without extra bracing; it is a modest addition on top of ordinary roof loading.

What this Rogers 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.
Rogers 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.)
