Layers
No third layer
On a roof that already carries two layers, or slate or tile, the code allows no recover: it is a tear-off (IRC R908.3.1.1). 19% of West Vincent’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. The contractor or the township code office in West Vincent will know.
