The rules for a reroof in River Edge
Permit
Detached houses: no permit, no notice
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). Attached houses (3% of River Edge’s homes) and any work that touches the structure fall outside the rule.
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. 82% of River Edge’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). River Edge is outside it, so whether to add one is up to you and the installer.
