The rules for a reroof in Doylestown Borough

Permit

Local ordinance, not the state

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

Layers

One old layer can stay; two cannot

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). 78% of Doylestown Borough’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. The contractor or the borough code office in Doylestown Borough will know.
