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. Attached houses (3% of Haddon’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. 90% of Haddon’s homes were built before 1980, so get the layer count and a tear-off price in writing.

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