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). With 25% of Mashpee’s homes were built before 1980, ask what is under the newest layer.

Ice barrier
Required in Mashpee, as in every Massachusetts town
Massachusetts answers “yes” to the ice barrier for every town. 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).
