Permit
Under 34 Pa. Code § 403.1(b)(8), alterations to a house that make no structural change are outside the state code. Whether Jermyn wants a permit is in its own ordinance; ask the borough code office before the old roof comes off.

Layers
IRC R908.3.1.1 forbids roofing over two existing layers, over slate or tile, or over a water-soaked roof. 82% of Jermyn’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 Jermyn’s says.

Of 924 occupied homes in Jermyn, 709 (77%) are owner-occupied. Counting by decade, 30% before 1940, 62% before 1960, 82% before 1980 of the housing was in place, and 6% dates from 2000 on. (ACS 2020–2024.)
The housing is 75% detached houses, 6% attached single-family houses (rowhouses, twins and townhouses), 15% 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.

Useful life is HUD’s planning figure, not a warranty. More in the guides to shingles, metal, slate and flat roofs.
| Material | HUD useful life | Fits a house like | Watch for |
|---|---|---|---|
| Asphalt shingles | 20 years | Most pitched roofs; 75% of homes here are detached | Wind class set by the design wind speed (IRC Table R905.2.4.1) |
| Metal (standing seam, panels) | 50 years | Roofs that will carry solar later | A complete standing-seam system may go over the old roof (R908.3.1) |
| Slate | 75 years | Older houses; 30% here predate 1940 | Sound slate can be reused (R908.5); broken slate cannot |
| Flat roof: EPDM or TPO | 15 years | Additions and porch roofs | Coating is not a replacement |
