The rules for a reroof in South Coventry
Layers
One old layer can stay; two cannot
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). 37% of South Coventry’s homes were built before 1980; many have been reroofed before.
Ice barrier
South Coventry’s climate table decides
IRC R905.1.2 calls for an ice barrier where Table R301.2 says so; in Pennsylvania the municipality completes that table. South Coventry’s answer is with the township code office.
