The rules for a reroof in Lower Pottsgrove
Permit
Lower Pottsgrove’s ordinance decides
Pennsylvania’s code leaves residential alterations without structural change to local ordinance (34 Pa. Code § 403.1(b)(8)). Whether Lower Pottsgrove wants a permit is in its own ordinance; ask the township code office before the old roof comes off.
IRC R908.3.1.1 forbids roofing over two existing layers, over slate or tile, or over a water-soaked roof. With 44% of Lower Pottsgrove’s homes were built before 1980, ask what is under the newest layer.
The code requires an ice barrier where the local climate table (Table R301.2) says so, and each Pennsylvania municipality fills that table in. Ask the township code office or the contractor what Lower Pottsgrove’s says.
