The rules for a reroof in Middletown Borough

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 borough code office in Middletown Borough is the one to ask before work starts.

Layers

No third layer

IRC R908.3.1.1 forbids roofing over two existing layers, over slate or tile, or over a water-soaked roof. With 78% of Middletown Borough’s homes were built before 1980, ask what is under the newest layer.

Ice barrier

Middletown Borough’s climate table decides

IRC R905.1.2 calls for an ice barrier where Table R301.2 says so; in Pennsylvania the municipality completes that table. Middletown Borough’s answer is with the borough code office.
