The rules for a reroof in Gibbsboro
Permit
None for a detached one- or two-family 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. Attached houses (1% of Gibbsboro’s homes) and any work that touches the structure fall outside the rule.
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. 72% of Gibbsboro’s homes were built before 1980: ask how many layers yours has and whether the price is for a tear-off to the deck.
The state code’s ice barrier applies where the average January day is 25 °F or colder: Sussex County, per DCA Bulletin 07-3. Gibbsboro is outside it, so whether to add one is up to you and the installer.
