Permit
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 83% of Franklin Township’s homes that are detached; twins, rowhouses, townhouses and structural work are outside it.

Layers
Which layers may stay is a Rehabilitation Subcode question in New Jersey (the IRC definitions are deleted by N.J.A.C. 5:23-3.21), and this site has not read that subcode yet. With 50% of Franklin Township’s homes were built before 1980, ask the contractor to count the layers before quoting.

Ice barrier
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 Franklin Township, ask whether the quote includes one anyway.
