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 East Goshen wants a permit is in its own ordinance; ask the township code office before the old roof comes off.

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). 46% of East Goshen’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. The contractor or the township code office in East Goshen will know.
Rules as read on October 24, 2026. Everything else the state requires: roof replacement in Pennsylvania.

| Slate | 75 years | Older and historic houses | Can’t be roofed over; check the framing for the weight |
| Flat roof: EPDM or TPO | 15 years | Low-slope roofs and rear sections (25% of homes here are attached) | Coating is not a replacement |
