The rules for a reroof in West Caldwell
Permit
None for a detached one- or two-family house
Under N.J.A.C. 5:23-2.7 a reroof of a detached one- or two-family house goes ahead without a permit or a notice to the construction office. That covers the 81% of West Caldwell’s homes that are detached; twins, rowhouses, townhouses and structural work are outside it.
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. 85% of West Caldwell’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). For West Caldwell, ask whether the quote includes one anyway.
