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 (4% of Netcong’s homes) and any work that touches the structure fall outside the rule.

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. 87% of Netcong’s homes were built before 1980, so get the layer count and a tear-off price in writing.

Ice barrier
Only Sussex County meets New Jersey’s 25 °F January test for a required ice barrier (N.J.A.C. 5:23-3.21; DCA Bulletin 07-3). Netcong is outside it, so whether to add one is up to you and the installer.

Storm reports are what observers logged, not a measure of damage to any roof. When wind or hail damage means a new roof.
Lifespans come from HUD’s capital-needs table, not from a brochure. More in the guides to shingles, metal, slate and flat roofs.

| Metal (standing seam, panels) | 50 years | Simple roofs with long, unbroken slopes | A complete standing-seam system may go over the old roof (R908.3.1) |
| Slate | 75 years | Older houses; 29% here predate 1940 | Can’t be roofed over; check the framing for the weight |
