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
Replacing the covering on a detached one- or two-family house needs no permit and no notice to the town (N.J.A.C. 5:23-2.7). Attached houses (15% of Eatontown’s homes) and any work that touches the structure fall outside the rule.

Layers
New Jersey deletes the IRC’s reroofing definitions (N.J.A.C. 5:23-3.21(c)2.xxii); its layer rule for existing houses is in the Rehabilitation Subcode, which this site has not read yet. With 65% of Eatontown’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). In Eatontown it is the installer’s and the manufacturer’s call; ask whether the quote includes it.
