New Roofing Costs connects homeowners with independent local roofing contractors. We do not perform roofing work.

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 76% of Yardley’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 Yardley’s says.
