Permit
Pennsylvania’s code leaves residential alterations without structural change to local ordinance (34 Pa. Code § 403.1(b)(8)). So the borough code office in Port Carbon is the one to ask before work starts.

Layers
IRC R908.3.1.1 forbids roofing over two existing layers, over slate or tile, or over a water-soaked roof. 94% of Port Carbon’s homes were built before 1980, so count the layers before comparing quotes.
Ice barrier
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). Ask the borough code office or the contractor what Port Carbon’s says.

Of 781 occupied homes in Port Carbon, 605 (78%) are owner-occupied. Counting by decade, 67% before 1940, 84% before 1960, 94% before 1980 of the housing was in place, and 3% dates from 2000 on. (ACS 2020–2024.)
The housing is 54% detached houses, 29% attached single-family houses (rowhouses, twins and townhouses), 10% buildings of two to four units.
Older houses hide their history: ask the contractor to confirm the deck (board or sheet) and every layer above it before pricing, because slate or two layers mean a full tear-off.
