The rules for a reroof in Bethel 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)). The township code office can say what Bethel Township requires.
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). 21% of Bethel Township’s homes were built before 1980, so count the layers before comparing quotes.
IRC R905.1.2 calls for an ice barrier where Table R301.2 says so; in Pennsylvania the municipality completes that table. Ask the township code office or the contractor what Bethel Township’s says.
