The rules for a reroof in Shrewsbury Borough
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). Attached houses (6% of Shrewsbury Borough’s homes) and any work that touches the structure fall outside the rule.
The state strikes the IRC reroof definitions from its code (N.J.A.C. 5:23-3.21) and leaves existing houses to the Rehabilitation Subcode, not yet checked here. 54% of Shrewsbury Borough’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. For Shrewsbury Borough, ask whether the quote includes one anyway.
