New Roofing Costs connects homeowners with independent local roofing contractors. We do not perform roofing work.
This number connects homeowners who are planning a new roof or a full roof replacement with independent local roofing contractors. It is not for leak repairs or patch jobs. The call must come from the homeowner who decides on the roof. Calls may be recorded.
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 Mahanoy City is the one to ask before work starts.
Source: 34 Pa. Code § 403.1(b)
Layers
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). 94% of Mahanoy City’s homes were built before 1980; many have been reroofed before.
Ice barrier
IRC R905.1.2 calls for an ice barrier where Table R301.2 says so; in Pennsylvania the municipality completes that table. The contractor or the borough code office in Mahanoy City will know.

57% of the occupied homes in Mahanoy City are lived in by their owners: 735 households, the people this line is for. Counting by decade, 75% before 1940, 85% before 1960, 94% before 1980 of the housing was in place, and 3% dates from 2000 on. (ACS 2020–2024.)
The housing is 20% detached houses, 68% attached single-family houses (rowhouses, twins and townhouses), 7% buildings of two to four units.
With about two in three 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.
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.

Storm reports are what observers logged, not a measure of damage to any roof. When wind or hail damage means a new roof.
HUD’s useful-life figures are for planning; a warranty is a separate promise. For Mahanoy City’s houses: 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; 20% 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 | Simple roofs with long, unbroken slopes | A complete standing-seam system may go over the old roof (R908.3.1) |
| Slate | 75 years | Older houses; 75% here predate 1940 | Can’t be roofed over; check the framing for the weight |
| Flat roof: EPDM or TPO | 15 years | Low-slope roofs and rear sections (68% of homes here are attached) | Coating is not a replacement |
