New Roofing Costs connects homeowners with independent local roofing contractors. We do not perform roofing work.

The rules for a reroof in Lodi
Permit
No permit for a detached house
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). In Lodi, 23% of homes are detached. An attached house, or work on rafters and beams, is not covered.
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. 83% of Lodi’s homes were built before 1980: ask how many layers yours has and whether the price is for a tear-off to the deck.
New Jersey requires the eave membrane only where January averages 25 °F or colder, which the state says is Sussex County (DCA Bulletin 07-3). In Lodi it is the installer’s and the manufacturer’s call; ask whether the quote includes it.
