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 Montrose is the one to ask before work starts.

The rules for a reroof in Montrose
Layers
No third layer
A new roof may go over one existing layer; with two or more, or over slate, clay or cement tile, everything comes off to the deck (IRC R908.3.1.1). 87% of Montrose’s homes were built before 1980, so count the layers before comparing quotes.
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 borough code office in Montrose will know.
