The rules for a reroof in Hartley

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 township code office in Hartley is the one to ask before work starts.

Source: 34 Pa. Code § 403.1(b)

Layers

No third layer

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). 64% of Hartley’s homes were built before 1980; many have been reroofed before.

Ice barrier

Set by the local climate table

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 Hartley will know.
