The rules for a reroof in Ipswich
Layers
One old layer can stay; two cannot
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). 64% of Ipswich’s homes were built before 1980; many have been reroofed before.

Ice barrier
Required in Ipswich, 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).

Wind and snow
118 mph design wind, 50 psf ground snow
Ipswich’s code design values are a 118 mph ultimate design wind speed and a 50 psf ground snow load (30 psf minimum flat-roof snow load). At that wind speed the code calls for asphalt shingles labeled ASTM D7158 Class G or H (Table R905.2.4.1).
