Woodlynne has 1,020 homes, and half of them were standing by 1938. Below: what the code asks of a replacement here, the permit, and the town’s own records.
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). That covers the 36% of Woodlynne’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. 96% of Woodlynne’s homes were built before 1980, so get the layer count and a tear-off price in writing.

Ice barrier
New Jersey requires the eave membrane only where January averages 25 °F or colder, which the state says is Sussex County (DCA Bulletin 07-3). In Woodlynne it is the installer’s and the manufacturer’s call; ask whether the quote includes it.

Rules as read on October 24, 2026. Code edition, permit and contract rules for the whole state: roof replacement in New Jersey.
Of 828 occupied homes in Woodlynne, 488 (59%) are owner-occupied. By year built, 60% before 1940, 84% before 1960, 96% before 1980; 0% went up in 2000 or later. (ACS 2020–2024.)
By building type: 36% detached houses, 48% attached single-family houses (rowhouses, twins and townhouses), 15% buildings of two to four units.
With about half of homes attached, many roofs here meet a neighbor’s roof at a party wall. Say so on the call, and ask the contractor how the new roof will be tied in where it meets the house next door. New Jersey’s no-permit rule for reroofing covers detached houses only, so an attached house is outside it.
On a house built before 1940, ask what the deck is (boards or plywood) and whether slate sits under the later layers: slate can’t be roofed over.
