Do I need a permit for roof replacement or repair in Hillsborough Township?
Often no. Roof replacement or repair is frequently exempt, but confirm with Hillsborough Township before you start.
Repairing or replacing the existing roof covering on a detached one- or two-family dwelling is ordinary maintenance, which may be done without a permit application or notice to the construction official (N.J.A.C. 5:23-2.7(a) and (c)1x). The exemption does not cover townhouses or other attached buildings, and work affecting structural safety, such as replacing rafters or other structural members, is never ordinary maintenance (N.J.A.C. 5:23-2.7(b)). Even without a permit the work must meet the code; the rehabilitation subcode requires tear-off before re-covering when the roof already has two or more layers, is water soaked or deteriorated, or is wood shake, slate, clay, or cement tile (N.J.A.C. 5:23-6.4).
