The rules for a reroof in Monaghan
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 Monaghan 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). 45% of Monaghan’s homes were built before 1980; many have been reroofed before.
Whether an eave membrane is a code item depends on the climate table the municipality filled in when it adopted the code (IRC R905.1.2, Table R301.2). The contractor or the township code office in Monaghan will know.
