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
Under N.J.A.C. 5:23-2.7 a reroof of a detached one- or two-family house goes ahead without a permit or a notice to the construction office. That covers the 98% of Fredon’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. With 55% of Fredon’s homes were built before 1980, ask the contractor to count the layers before quoting.

Ice barrier
New Jersey requires an eave ice barrier where January averages 25 °F or colder, and names Sussex County as that area (N.J.A.C. 5:23-3.21(c)8.ii; DCA Bulletin 07-3). Fredon is in it.

Storm reports are what observers logged, not a measure of damage to any roof. When wind or hail damage means a new roof.
Useful life is HUD’s planning figure, not a warranty. More in the guides to shingles, metal, slate and flat roofs.
| Material | HUD useful life | Fits a house like | Watch for |
|---|---|---|---|
| Asphalt shingles | 20 years | Most pitched roofs; 98% of homes here are detached | Wind class set by the design wind speed (IRC Table R905.2.4.1) |
| Metal (standing seam, panels) | 50 years | Roofs that will carry solar later | A complete standing-seam system may go over the old roof (R908.3.1) |
| Slate | 75 years | Older houses; 11% here predate 1940 | Can’t be roofed over; check the framing for the weight |
| Flat roof: EPDM or TPO | 15 years | Additions and porch roofs | Seams at walls and drainage |
