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 township code office in Lower Mifflin is the one to ask before work starts.

The rules for a reroof in Lower Mifflin
Layers
No third layer
On a roof that already carries two layers, or slate or tile, the code allows no recover: it is a tear-off (IRC R908.3.1.1). 42% of Lower Mifflin’s homes were built before 1980; many have been reroofed before.
Ice barrier
Set by the local climate table
IRC R905.1.2 calls for an ice barrier where Table R301.2 says so; in Pennsylvania the municipality completes that table. Lower Mifflin’s answer is with the township code office.
