Permit
The state code does not cover a reroof that changes no structure (34 Pa. Code § 403.1(b)(8)). Whether Hatfield Borough wants a permit is in its own ordinance; ask the borough code office before the old roof comes off.

Layers
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 67% of Hatfield Borough’s homes were built before 1980, ask what is under the newest layer.
Ice barrier
The code requires an ice barrier where the local climate table (Table R301.2) says so, and each Pennsylvania municipality fills that table in. The contractor or the borough code office in Hatfield Borough will know.
