Norwood has 2,001 homes, and half of them were standing by 1986. What the code requires when that roof is replaced, and who signs off, is below.
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 (17% of Norwood’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 42% of Norwood’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. For Norwood, ask whether the quote includes one anyway.

Useful life is HUD’s planning figure, not a warranty. More in the guides to shingles, metal, slate and flat roofs.
