Permit

Ask Orange 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 Orange is the one to ask before work starts.

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). 44% of Orange’s homes were built before 1980, so count the layers before comparing quotes.

Ice barrier

Orange’s climate table decides

Whether an eave membrane is a code item depends on the climate table the municipality filled in when it adopted the code (IRC R905.1.2, Table R301.2). Orange’s answer is with the township code office.
