The rules for a reroof in Coopersburg
Layers
Two layers means a tear-off
IRC R908.3.1.1 forbids roofing over two existing layers, over slate or tile, or over a water-soaked roof. With 85% of Coopersburg’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. Ask the borough code office or the contractor what Coopersburg’s says.
