Permit
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 Manheim Borough is the one to ask before work starts.

Layers
IRC R908.3.1.1 forbids roofing over two existing layers, over slate or tile, or over a water-soaked roof. With 87% of Manheim Borough’s homes were built before 1980, ask what is under the newest layer.
Ice barrier
IRC R905.1.2 calls for an ice barrier where Table R301.2 says so; in Pennsylvania the municipality completes that table. Manheim Borough’s answer is with the borough code office.
