Layers

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). 53% of Jackson Township’s homes were built before 1980; many have been reroofed before.

Ice barrier

Set by the local climate table

The code requires an ice barrier where the local climate table (Table R301.2) says so, and each Pennsylvania municipality fills that table in. Jackson Township’s answer is with the township code office.
