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). In Glen Ridge, 86% 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. With 92% of Glen Ridge’s homes were built before 1980, ask the contractor to count the layers before quoting.

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 Glen Ridge it is the installer’s and the manufacturer’s call; ask whether the quote includes it.

Owners live in 2,268 of Glen Ridge’s occupied homes, or 91%. Counting by decade, 81% before 1940, 86% before 1960, 92% before 1980 of the housing was in place, and 5% dates from 2000 on. (ACS 2020–2024.)

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.

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