The rules for a reroof in Westhampton

One old layer can stay; two cannot
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). 64% of Westhampton’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.
