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 Ridgefield, 43% of homes are detached. An attached house, or work on rafters and beams, is not covered.

Layers
Which layers may stay is a Rehabilitation Subcode question in New Jersey (the IRC definitions are deleted by N.J.A.C. 5:23-3.21), and this site has not read that subcode yet. 80% of Ridgefield’s homes were built before 1980, so get the layer count and a tear-off price in writing.
