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. 56% of Kinnelon’s homes were built before 1980: ask how many layers yours has and whether the price is for a tear-off to the deck.

Ice barrier
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 Kinnelon, ask whether the quote includes one anyway.
