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
Pennsylvania’s code leaves residential alterations without structural change to local ordinance (34 Pa. Code § 403.1(b)(8)). So the borough code office in Windsor Borough is the one to ask before work starts.

Layers
On a roof that already carries two layers, or slate or tile, the code allows no recover: it is a tear-off (IRC R908.3.1.1). With 95% of Windsor Borough’s homes were built before 1980, ask what is under the newest layer.
Ice barrier
The code requires an ice barrier where the local climate table (Table R301.2) says so, and each Pennsylvania municipality fills that table in. Windsor Borough’s answer is with the borough code office.

Owners live in 236 of Windsor Borough’s occupied homes, or 50%. Counting by decade, 52% before 1940, 75% before 1960, 95% before 1980 of the housing was in place, and 2% dates from 2000 on. (ACS 2020–2024.)
The housing is 43% detached houses, 28% attached single-family houses (rowhouses, twins and townhouses), 9% buildings of two to four units.
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.
