The rules for a reroof in South Hanover
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). 31% of South Hanover’s homes were built before 1980; many have been reroofed before.
Ice barrier
Set by the local climate table
IRC R905.1.2 calls for an ice barrier where Table R301.2 says so; in Pennsylvania the municipality completes that table. South Hanover’s answer is with the township code office.
Checked against the code text on October 24, 2026. Everything else the state requires: roof replacement in Pennsylvania.
