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). 42% of Manor’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 Manor’s says.
