Amity has 4,993 homes, and half of them were standing by 1990. 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
The state code does not cover a reroof that changes no structure (34 Pa. Code § 403.1(b)(8)). Whether Amity wants a permit is in its own ordinance; ask the township code office before the old roof comes off.
Source: 34 Pa. Code § 403.1(b)
Layers
On a roof that already carries two layers, or slate or tile, the code allows no recover: it is a tear-off (IRC R908.3.1.1). 41% of Amity’s homes were built before 1980, so count the layers before comparing quotes.
Ice barrier
IRC R905.1.2 calls for an ice barrier where Table R301.2 says so; in Pennsylvania the municipality completes that table. Ask the township code office or the contractor what Amity’s says.

Owners live in 4,013 of Amity’s occupied homes, or 84%. By year built, 5% before 1940, 10% before 1960, 41% before 1980; 33% went up in 2000 or later. (ACS 2020–2024.)
By building type: 76% detached houses, 7% attached single-family houses (rowhouses, twins and townhouses), 5% manufactured homes.
33% of homes here were built in 2000 or later. HUD’s useful-life table gives an asphalt-shingle roof 20 years, so roofs on houses from the early 2000s are reaching that age.
Of the 67 Berks County municipalities on this site, Amity has the 60th largest share of homes built before 1980: 41%, against a county range of 18% to 97%.

A report says hail fell near Amity, not that it damaged a 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 Amity’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; 76% 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 | Standing seam that carries its own loads can skip the tear-off (R908.3.1) |
| Slate | 75 years | Older houses; 5% here predate 1940 | Can’t be roofed over; check the framing for the weight |
| Flat roof: EPDM or TPO | 15 years | Porches, additions, low-slope rears | Coating is not a replacement |
Pennsylvania’s home improvement law (HICPA § 3, § 6) requires registration with the Attorney General from $5,000 a year of such work and puts the number on every estimate; ask for it in Amity and look it up.
The price side is in what a new roof costs in Pennsylvania; the paperwork side in checking a roofing contractor.
