Kennebec County, ME Roof Snow Load - 56 psf

Kennebec County, ME: your roof's ASCE 7 snow number, in plain English

Very heavy
56 psf

Kennebec County's roofs are built to hold 56 psf of snow, the ASCE 7-22 figure a permit reviewer checks first.

In depth, not weight: that's roughly 123.2 inches of fresh, light snow, 44.8 inches of old, settled snow, or as little as 11.2 inches of solid ice - snow that heavy is rare here but ice from a freeze-thaw cycle adds up far faster than the depth suggests. Few counties map a higher design load outside case-study terrain; regular roof snow removal and structural inspection are standard practice at this level.

Before you rely on Kennebec County's number

Treat the Kennebec County figure as a starting point, not a final answer: it assumes standard occupancy, a heated structure and a moderately sheltered site, per ASCE 7-22's own defaults. Exposed terrain, an unheated building or a steeper roof all shift the real number.

For a real application, skip the county number and go straight to the ASCE 7 Hazard Tool - enter your coordinates and it returns a site-specific figure a plan reviewer will recognize. See the methodology guide.
