The rules for a reroof in Neptune
Permit
No permit for a detached house
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). In Neptune, 66% of homes are detached. An attached house, or work on rafters and beams, is not covered.
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. 69% of Neptune’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). For Neptune, ask whether the quote includes one anyway.
