Half of the 950 homes in Brooklawn were built before 1938. The rules below decide how much of the old roof has to come off and what goes under the new one.
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 Brooklawn, 45% of homes are detached. An attached house, or work on rafters and beams, is not covered.

Layers
New Jersey deletes the IRC’s reroofing definitions (N.J.A.C. 5:23-3.21(c)2.xxii); its layer rule for existing houses is in the Rehabilitation Subcode, which this site has not read yet. 97% of Brooklawn’s homes were built before 1980: ask how many layers yours has and whether the price is for a tear-off to the deck.

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

Rules as read on October 24, 2026. Everything else the state requires: roof replacement in New Jersey.
Of 884 occupied homes in Brooklawn, 721 (82%) are owner-occupied. By year built, 60% before 1940, 90% before 1960, 97% before 1980; 1% went up in 2000 or later. (ACS 2020–2024.)
By building type: 45% detached houses, 45% attached single-family houses (rowhouses, twins and townhouses), 8% buildings of two to four units.
With 45% 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.

A report says hail fell near Brooklawn, not that it damaged a roof. When wind or hail damage means a new roof.

| Slate | 75 years | Older houses; 60% here predate 1940 | Can’t be roofed over; check the framing for the weight |
