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. In Middletown, 78% of homes are detached. An attached house, or work on rafters and beams, is not covered.

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 66% of Middletown’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 Middletown it is the installer’s and the manufacturer’s call; ask whether the quote includes it.
