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
New Jersey treats a new covering on a detached one- or two-family house as ordinary maintenance: no permit, no notice (N.J.A.C. 5:23-2.7). Attached houses (1% of Wenonah’s homes) and any work that touches the structure fall outside the rule.

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 87% of Wenonah’s homes were built before 1980, ask the contractor to count the layers before quoting.

Ice barrier
The state code’s ice barrier applies where the average January day is 25 °F or colder: Sussex County, per DCA Bulletin 07-3. In Wenonah it is the installer’s and the manufacturer’s call; ask whether the quote includes it.

93% of the occupied homes in Wenonah are lived in by their owners: 783 households, the people this line is for. Counting by decade, 45% before 1940, 67% before 1960, 87% before 1980 of the housing was in place, and 6% dates from 2000 on. (ACS 2020–2024.)
The housing is 93% detached houses, 6% buildings of two to four units.
Older houses hide their history: ask the contractor to confirm the deck (board or sheet) and every layer above it before pricing, because slate or two layers mean a full tear-off.
Of the 24 Gloucester County municipalities on this site, Wenonah has the 5th largest share of homes built before 1980: 87%, against a county range of 7% to 89%.
