The median home in Aberdeen was built in 1970; there are 8,219 of them. 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
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 61% of Aberdeen’s homes that are detached; twins, rowhouses, townhouses and structural work are outside it.

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. 60% of Aberdeen’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
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). Aberdeen is outside it, so whether to add one is up to you and the installer.

Lifespans come from HUD’s capital-needs table, not from a brochure. More in the guides to shingles, metal, slate and flat roofs.
