Layers

No third layer

A new roof may go over one existing layer; with two or more, or over slate, clay or cement tile, everything comes off to the deck (IRC R908.3.1.1). 75% of Walnutport’s homes were built before 1980, so count the layers before comparing quotes.

Ice barrier

Walnutport’s climate table decides

The code requires an ice barrier where the local climate table (Table R301.2) says so, and each Pennsylvania municipality fills that table in. Ask the borough code office or the contractor what Walnutport’s says.

A contractor who does $5,000 or more of home improvement work a year must be registered with the Pennsylvania Attorney General, and the number has to be on every contract and estimate (HICPA § 3, § 6). Ask for it before anyone starts on a roof in Walnutport, and search it.
