The rules for a reroof in Lower Swatara

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). With 46% of Lower Swatara’s homes were built before 1980, ask what is under the newest layer.

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. Lower Swatara’s answer is with the township code office.
