The rules for a reroof in Dalton

Permit

Roofing is not exempt

Roofing is not on the Massachusetts list of work exempt from a permit (780 CMR 51.00, R105.2). Dalton’s building department issues it, and the application carries the contractor’s HIC registration number.

Layers

One old layer can stay; two cannot

A new roof may go over one existing layer; with two or more, or over slate, clay or cement tile, everything comes off to the deck (IRC R908.3.1.1). 79% of Dalton’s homes were built before 1980, so count the layers before comparing quotes.

Ice barrier

Required in Dalton, as in every Massachusetts town

The state’s climate table marks the ice barrier “yes” statewide. That is a self-adhering membrane, or two cemented layers of underlayment, from the eave to at least 24 inches inside the wall line (IRC R905.1.2).

Wind and snow

112 mph design wind, 60 psf ground snow
