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 Colerain wants a permit is in its own ordinance; ask the township 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. 38% of Colerain’s homes were built before 1980, so count the layers before comparing quotes.
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. Colerain’s answer is with the township code office.

Owners live in 986 of Colerain’s occupied homes, or 84%. Counting by decade, 11% before 1940, 18% before 1960, 38% before 1980 of the housing was in place, and 36% dates from 2000 on. (ACS 2020–2024.)
The housing is 79% detached houses, 15% attached single-family houses (rowhouses, twins and townhouses), 5% manufactured homes.
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.
Of the 59 Lancaster County municipalities on this site, Colerain has the 49th largest share of homes built before 1980: 38%, against a county range of 27% to 87%.

| Material | HUD useful life | Fits a house like | Watch for |

| Slate | 75 years | Older houses; 11% here predate 1940 | Can’t be roofed over; check the framing for the weight |
