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 N.J.A.C. 5:23-2.7 a reroof of a detached one- or two-family house goes ahead without a permit or a notice to the construction office. That covers the 81% of Fairfield Township’s homes that are detached; twins, rowhouses, townhouses and structural work are outside it.

Layers
The state strikes the IRC reroof definitions from its code (N.J.A.C. 5:23-3.21) and leaves existing houses to the Rehabilitation Subcode, not yet checked here. With 68% of Fairfield Township’s homes were built before 1980, ask the contractor to count the layers before quoting.

Ice barrier
Only Sussex County meets New Jersey’s 25 °F January test for a required ice barrier (N.J.A.C. 5:23-3.21; DCA Bulletin 07-3). Fairfield Township is outside it, so whether to add one is up to you and the installer.
