New Roofing Costs connects homeowners with independent local roofing contractors. We do not perform roofing work.
This number connects homeowners who are planning a new roof or a full roof replacement with independent local roofing contractors. It is not for leak repairs or patch jobs. The call must come from the homeowner who decides on the roof. Calls may be recorded.
Permit
Under 34 Pa. Code § 403.1(b)(8), alterations to a house that make no structural change are outside the state code. So the borough code office in Perkasie is the one to ask before work starts.

Layers
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). With 60% of Perkasie’s homes were built before 1980, ask what is under the newest layer.
Ice barrier
IRC R905.1.2 calls for an ice barrier where Table R301.2 says so; in Pennsylvania the municipality completes that table. Ask the borough code office or the contractor what Perkasie’s says.
