The rules for a reroof in Chapman

Permit

Ask Chapman first

Under 34 Pa. Code § 403.1(b)(8), alterations to a house that make no structural change are outside the state code. So the township code office in Chapman is the one to ask before work starts.

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. 64% of Chapman’s homes were built before 1980; many have been reroofed before.

Ice barrier

Chapman’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. Ask the township code office or the contractor what Chapman’s says.
