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 Jackson Township wants a permit is in its own ordinance; ask the township code office before the old roof comes off.

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 44% of Jackson Township’s homes were built before 1980, ask what is under the newest layer.
Ice barrier
IRC R905.1.2 calls for an ice barrier where Table R301.2 says so; in Pennsylvania the municipality completes that table. The contractor or the township code office in Jackson Township will know.

87% of the occupied homes in Jackson Township are lived in by their owners: 3,228 households, the people this line is for. Counting by decade, 16% before 1940, 23% before 1960, 44% before 1980 of the housing was in place, and 38% dates from 2000 on. (ACS 2020–2024.)
The housing is 68% detached houses, 20% attached single-family houses (rowhouses, twins and townhouses), 9% manufactured homes.
38% 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.
Of the 57 York County municipalities on this site, Jackson Township has the 38th largest share of homes built before 1980: 44%, against a county range of 25% to 98%.
