The rules for a reroof in Norwell

Permit

Roofing is not exempt

The residential code’s permit-exempt list (R105.2) has no roofing line. The application to Norwell’s building department carries the contractor’s HIC number (R105.3).

Source: 780 CMR 51.00, Chapter 1 amendments (R105)

Layers

No third layer

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). 68% of Norwell’s homes were built before 1980; many have been reroofed before.

Ice barrier

Required statewide

Massachusetts answers “yes” to the ice barrier for every town. 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.
