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
The state code does not cover a reroof that changes no structure (34 Pa. Code § 403.1(b)(8)). Whether Lititz wants a permit is in its own ordinance; ask the borough code office before the old roof comes off.

Layers
IRC R908.3.1.1 forbids roofing over two existing layers, over slate or tile, or over a water-soaked roof. 68% of Lititz’s homes were built before 1980; many have been reroofed before.
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 Lititz’s says.

Owners live in 2,521 of Lititz’s occupied homes, or 64%. By year built, 32% before 1940, 48% before 1960, 68% before 1980; 13% went up in 2000 or later. (ACS 2020–2024.)
By building type: 43% detached houses, 29% attached single-family houses (rowhouses, twins and townhouses), 11% buildings of two to four units.
On a house built before 1940, ask what the deck is (boards or plywood) and whether slate sits under the later layers: slate can’t be roofed over.
