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 90% of Harrington Park’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 81% of Harrington Park’s homes were built before 1980, ask the contractor to count the layers before quoting.

Ice barrier
The state code’s ice barrier applies where the average January day is 25 °F or colder: Sussex County, per DCA Bulletin 07-3. Harrington Park is outside it, so whether to add one is up to you and the installer.
