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). 62% of Pennsburg’s homes were built before 1980, so count the layers before comparing quotes.
Ice barrier
Pennsburg’s climate table decides
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 borough code office in Pennsburg will know.
