The rules for a reroof in Hazlet
Permit
No permit for a detached house
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 82% of Hazlet’s homes that are detached; twins, rowhouses, townhouses and structural work are outside it.
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. 78% of Hazlet’s homes were built before 1980: ask how many layers yours has and whether the price is for a tear-off to the deck.
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). Hazlet is outside it, so whether to add one is up to you and the installer.
