The rules for a reroof in Harvard

Permit

A permit from Harvard

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

Layers

No third layer

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). With 59% of Harvard’s homes were built before 1980, ask what is under the newest layer.

Ice barrier

Required statewide

There is no local exception: the state table says “yes.” 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).
