The median home in Folcroft was built in 1960; there are 2,740 of them. The rules below decide how much of the old roof has to come off and what goes under the new one.
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
Under 34 Pa. Code § 403.1(b)(8), alterations to a house that make no structural change are outside the state code. Whether Folcroft 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. 93% of Folcroft’s homes were built before 1980, so count the layers before comparing quotes.
Ice barrier
The code requires an ice barrier where the local climate table (Table R301.2) says so, and each Pennsylvania municipality fills that table in. Folcroft’s answer is with the borough code office.

Owners live in 1,735 of Folcroft’s occupied homes, or 68%. Counting by decade, 8% before 1940, 49% before 1960, 93% before 1980 of the housing was in place, and 1% dates from 2000 on. (ACS 2020–2024.)
The housing is 10% detached houses, 78% attached single-family houses (rowhouses, twins and townhouses).
With about four in five 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.

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; 10% 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 | Low pitches and long runs | A complete standing-seam system may go over the old roof (R908.3.1) |
| Slate | 75 years | Older houses; 8% here predate 1940 | Sound slate can be reused (R908.5); broken slate cannot |
| Flat roof: EPDM or TPO | 15 years | Low-slope roofs and rear sections (78% of homes here are attached) | Coating is not a replacement |
