The rules for a reroof in Hampden

Permit

Ask Hampden first

The state code does not cover a reroof that changes no structure (34 Pa. Code § 403.1(b)(8)). So the township code office in Hampden is the one to ask before work starts.

Layers

Two layers means a tear-off

A new roof may go over one existing layer; with two or more, or over slate, clay or cement tile, everything comes off to the deck (IRC R908.3.1.1). 39% of Hampden’s homes were built before 1980, so count the layers before comparing quotes.

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 township code office or the contractor what Hampden’s says.
