Layers
No third layer
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). 86% of North York’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 borough code office or the contractor what North York’s says.

Homes and roofs in North York
39% of the occupied homes in North York are lived in by their owners: 416 households, the people this line is for. Counting by decade, 46% before 1940, 71% before 1960, 86% before 1980 of the housing was in place, and 12% dates from 2000 on. (ACS 2020–2024.)
The housing is 12% detached houses, 44% attached single-family houses (rowhouses, twins and townhouses), 29% buildings of two to four units.
With 44% of homes attached, many roofs here meet a neighbor’s roof at a party wall. Say so on the call, and ask the contractor how the new roof will be tied in where it meets the house next door.
Older houses hide their history: ask the contractor to confirm the deck (board or sheet) and every layer above it before pricing, because slate or two layers mean a full tear-off.
Of the 57 York County municipalities on this site, North York has the 6th largest share of homes built before 1980: 86%, against a county range of 25% to 98%.
