Layers
Two layers means a tear-off
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 77% of Warwick’s homes were built before 1980, ask what is under the newest layer.

Ice barrier
Required in Warwick, as in every Rhode Island town
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).
