The rules for a reroof in Carroll Valley

Local ordinance, not the state

The state code does not cover a reroof that changes no structure (34 Pa. Code § 403.1(b)(8)). The borough code office can say what Carroll Valley requires.

Layers

No third layer

Ice barrier

Set by the local climate table

IRC R905.1.2 calls for an ice barrier where Table R301.2 says so; in Pennsylvania the municipality completes that table. The contractor or the borough code office in Carroll Valley will know.
