The rules for a reroof in Penn Township
Permit
Local ordinance, not the state
Pennsylvania’s code leaves residential alterations without structural change to local ordinance (34 Pa. Code § 403.1(b)(8)). Whether Penn Township wants a permit is in its own ordinance; ask the township code office before the old roof comes off.
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). 30% of Penn Township’s homes were built before 1980; many have been reroofed before.
IRC R905.1.2 calls for an ice barrier where Table R301.2 says so; in Pennsylvania the municipality completes that table. Penn Township’s answer is with the township code office.
