Layers

Two layers means a tear-off

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). 46% of East Cocalico’s homes were built before 1980, so count the layers before comparing quotes.

Ice barrier

Set by the local climate table

IRC R905.1.2 calls for an ice barrier where Table R301.2 says so; in Pennsylvania the municipality completes that table. The contractor or the township code office in East Cocalico will know.
