The rules for a reroof in West Brandywine
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 34% of West Brandywine’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. West Brandywine’s answer is with the township code office.
