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 Clay Township 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). 61% of Clay Township’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 Clay Township’s says.
