Lincoln County, ME Roof Snow Load - 35 psf
Lincoln County, ME roof snow load, translated
A typical heated home in Lincoln County is designed to carry 35 pounds per square foot of snow on its roof, per ASCE 7-22.
On a roof that means 77 in. of fresh snow, 28 in. once it packs down, or 7 in. of solid ice - three very different piles for the same load. 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.

The figure above assumes the case ASCE 7-22 treats as typical: a heated, ordinary-occupancy home on a partially exposed site. Change any of those - exposure, heating, roof pitch, occupancy category - and the real design number moves.
A building permit needs the number at your exact address, not the county average - the free ASCE 7 Hazard Tool returns that from your coordinates in about a minute and produces a PDF a plan reviewer will accept. See the methodology guide.
