The rules for a reroof in Brockton

Permit

Roofing is not exempt

Roofing is not on the Massachusetts list of work exempt from a permit (780 CMR 51.00, R105.2). In Brockton the building department takes the application, with the contractor’s home improvement registration on it.

Layers

Two layers means a tear-off

On a roof that already carries two layers, or slate or tile, the code allows no recover: it is a tear-off (IRC R908.3.1.1). 81% of Brockton’s homes were built before 1980, so count the layers before comparing quotes.

Ice barrier

Required statewide

The state’s climate table marks the ice barrier “yes” statewide. It runs from the eave to 24 inches inside the exterior wall, more on steep roofs (IRC R905.1.2); check that the quote lists it.
