The rules for a reroof in Oakland
Permit
None for a detached one- or two-family house
Replacing the covering on a detached one- or two-family house needs no permit and no notice to the town (N.J.A.C. 5:23-2.7). That covers the 91% of Oakland’s homes that are detached; twins, rowhouses, townhouses and structural work are outside it.
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. 82% of Oakland’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 Oakland, ask whether the quote includes one anyway.
