Permit
Ashland Borough’s ordinance decides
Pennsylvania’s code leaves residential alterations without structural change to local ordinance (34 Pa. Code § 403.1(b)(8)). Whether Ashland Borough wants a permit is in its own ordinance; ask the borough code office before the old roof comes off.
IRC R908.3.1.1 forbids roofing over two existing layers, over slate or tile, or over a water-soaked roof. With 93% of Ashland Borough’s homes were built before 1980, ask what is under the newest layer.
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 Ashland Borough will know.
72% of the occupied homes in Ashland Borough are lived in by their owners: 837 households, the people this line is for. By year built, 71% before 1940, 83% before 1960, 93% before 1980; 1% went up in 2000 or later. (ACS 2020–2024.)
By building type: 33% detached houses, 51% attached single-family houses (rowhouses, twins and townhouses), 9% buildings of two to four units.
With about half of homes attached, many roofs here meet a neighbor’s roof at a party wall. Say so on the call, and ask the contractor how the new roof will be tied in where it meets the house next door.
On a house built before 1940, ask what the deck is (boards or plywood) and whether slate sits under the later layers: slate can’t be roofed over.
