Permit
Local ordinance, not the state
The state code does not cover a reroof that changes no structure (34 Pa. Code § 403.1(b)(8)). So the borough code office in Paxtang is the one to ask before work starts.

The rules for a reroof in Paxtang
Layers
One old layer can stay; two cannot
IRC R908.3.1.1 forbids roofing over two existing layers, over slate or tile, or over a water-soaked roof. With 100% of Paxtang’s homes were built before 1980, ask what is under the newest layer.
Ice barrier
Set by the local climate table
The code requires an ice barrier where the local climate table (Table R301.2) says so, and each Pennsylvania municipality fills that table in. Ask the borough code office or the contractor what Paxtang’s says.
