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
Under 34 Pa. Code § 403.1(b)(8), alterations to a house that make no structural change are outside the state code. Whether Carroll Township wants a permit is in its own ordinance; ask the township code office before the old roof comes off.

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). 34% of Carroll Township’s homes were built before 1980; many have been reroofed before.
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. Carroll Township’s answer is with the township code office.

The housing is 88% detached houses, 3% attached single-family houses (rowhouses, twins and townhouses).
36% of homes here were built in 2000 or later. HUD’s useful-life table gives an asphalt-shingle roof 20 years, so roofs on houses from the early 2000s are reaching that age.
