Roof replacement in Manayunk
Covers Manayunk, Wissahickon and Germany Hill, in the city's Lower Northwest planning district. Most owner-occupied homes here, 84%, are rowhomes or twins: houses that share at least one wall, so a new roof has to meet the neighbors' on one side or both.
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.

What the roof job looks like here
The City's own Rowhouse Manual puts it plainly: "Most rowhouse roofs appear 'flat', although they are actually gently sloped toward a drain." Replacing one means a low-slope membrane, run up the parapet and sealed where it meets the roofs next door.

Historic designation

For a designated property the City's EZ re-roofing standard does not apply "without prior approval" of the Historical Commission, so the commission's sign-off comes before the permit, and a change of material, such as slate to asphalt, is part of what it looks at.
