One old layer can stay; two cannot

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). With 38% of Rapho’s homes were built before 1980, ask what is under the newest layer.

Ice barrier

The code requires an ice barrier where the local climate table (Table R301.2) says so, and each Pennsylvania municipality fills that table in. The contractor or the township code office in Rapho will know.
