The rules for a reroof in Avon-by-the-Sea
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 73% of Avon-by-the-Sea’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. 78% of Avon-by-the-Sea’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. Avon-by-the-Sea is outside it, so whether to add one is up to you and the installer.
