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.
The rules for a reroof in Spring Grove
Permit
Local ordinance, not the state
Pennsylvania’s code leaves residential alterations without structural change to local ordinance (34 Pa. Code § 403.1(b)(8)). So the borough code office in Spring Grove is the one to ask before work starts.
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). 66% of Spring Grove’s homes were built before 1980; many have been reroofed before.
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 borough code office in Spring Grove will know.

Homes and roofs in Spring Grove
60% of the occupied homes in Spring Grove are lived in by their owners: 561 households, the people this line is for. Counting by decade, 37% before 1940, 51% before 1960, 66% before 1980 of the housing was in place, and 19% dates from 2000 on. (ACS 2020–2024.)
The housing is 51% detached houses, 20% attached single-family houses (rowhouses, twins and townhouses), 13% buildings of two to four units.
Older houses hide their history: ask the contractor to confirm the deck (board or sheet) and every layer above it before pricing, because slate or two layers mean a full tear-off.
