Roofing in King of Prussia: Upper Merion’s Rules, Explained
King of Prussia takes its name from the King of Prussia Inn, an 18th-century tavern. It’s part of Upper Merion Township, next to Valley Forge National Historical Park, and home to the King of Prussia Mall.
The homes we see in King of Prussia
Residential King of Prussia mixes post-war ranches, split-levels and Cape Cods with townhouse, condo and apartment communities built since the 1970s — about 30% of its homes date from 2000 or later. Many of the older houses have already had one re-roof, and some have two layers of shingles.
- Older homes with layered roofs: Upper Merion allows no more than two
- Deck checks after tear-off, with sheathing to the township’s minimums
- Low-slope additions and porches that need membrane roofing
- HOA and condo association approvals on townhouse roofs
Upper Merion’s roofing requirements
Upper Merion Township requires a roofing questionnaire describing the existing and proposed materials with every roofing permit. Its rules allow no more than two layers of asphalt, fiberglass or low-slope roofing, and no new roof over slate, wood shake, asbestos or clay tile. Roof sheathing must be at least 1/2″ over rafters 16″ on center, and at least 5/8″ with H-clips where rafters are farther apart. The permit has to be posted on the front of the building. We handle all of it.
