The rules for a reroof in Lower Oxford
Permit
Ask Lower Oxford first
The state code does not cover a reroof that changes no structure (34 Pa. Code § 403.1(b)(8)). Whether Lower Oxford 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). 35% of Lower Oxford’s homes were built before 1980, so count the layers before comparing quotes.
The code requires an ice barrier where the local climate table (Table R301.2) says so, and each Pennsylvania municipality fills that table in. The contractor or the township code office in Lower Oxford will know.
