Society Hill Contains Some of the Oldest Surviving Rooflines in America
Central Philadelphia
Roofers in Society Hill, PA
Society Hill is the most intensively preserved historic neighborhood in Philadelphia, with residential structures dating to the late 17th and early 18th centuries concentrated near Head House Square and along the blocks east of 4th Street. Working on a Society Hill roof is unlike working anywhere else in the city. The Philadelphia Historical Commission has review authority over exterior changes on many properties here. Using the wrong material or skipping the Certificate of Appropriateness process can result in a mandatory stop-work order and required removal of the new installation at the owner’s expense.
Honest Roofing has worked on historic structures in Philadelphia long enough to know that Society Hill requires a different pre-project sequence than any other neighborhood. Before any scope is proposed, we verify the property designation status, advise on Commission requirements, and use drone inspection to document the full existing roof condition. That documentation supports the Certificate of Appropriateness application where one is required and establishes a clear baseline for any insurance or permit record.
Philadelphia Historical Commission Expertise and Forty Years of Roofing History Behind Every Society Hill Inspection
Gordon Kulp founded Honest Roofing more than 40 years ago. The company has worked on historic structures across Philadelphia that require Historical Commission coordination, including properties with original slate, clay tile, and specialty flashing systems that must be matched or replaced with Commission-approved materials. Honest Roofing holds GAF Certified Commercial Contractor status and employs installers with direct experience on designated historic properties.
Honest Roofing employs FAA-Certified Drone Pilots. Society Hill narrow historic streets and dense rowhouse blocks create access conditions where conventional ladder inspection is often impractical on taller properties. Drone inspection documents every section of the roof surface from above and provides photograph-supported condition notes that the Historical Commission recognizes as adequate documentation for Certificate of Appropriateness applications. We hold a 4.8 rating from 70 Google reviews.
Why Society Hill Roofing Requires Regulatory Knowledge That Most Philadelphia Contractors Simply Do Not Have
Society Hill is a Central Philadelphia neighborhood bounded by Walnut Street to the north, Lombard Street to the south, 8th Street to the west, and the Delaware River waterfront to the east. It contains some of the oldest surviving residential architecture in the United States, with structures dating to the late 17th century concentrated near Head House Square.
A significant portion of Society Hill falls within the Society Hill Historic District. Properties within this district, or with individual historic designation, require a Certificate of Appropriateness from the Philadelphia Historical Commission before exterior changes, including roofing material changes, can be made. Proceeding without approval on a contributing structure can result in a mandatory stop-work order and required removal of the new installation at the owner’s expense.
For flat roof sections on Society Hill historic rowhouses, the Philadelphia Historical Commission is generally less restrictive on material choice because the roof surface is not visible from the street. TPO, EPDM, and modified bitumen systems are typically acceptable for these sections. Parapet wall caps and visible flashing materials may require separate review if they alter the streetscape appearance.

Do I need Philadelphia Historical Commission approval before replacing my roof in Society Hill?
Most likely yes, if your property carries individual historic designation or is a contributing structure within the Society Hill Historic District. You will need a Certificate of Appropriateness from the Philadelphia Historical Commission before making any exterior changes, including roof replacement or changes to roofing material. The application requires documentation of the existing roof, a description of the proposed replacement material, and evidence that the new material matches the historic character of the structure.
Proceeding without the required Certificate of Appropriateness on a contributing Society Hill property can result in a mandatory stop-work order and required removal of the new installation at the owner’s expense. Honest Roofing advises every Society Hill client on their specific designation status before any work is scheduled, assists with documentation for the Certificate of Appropriateness application where required, and does not begin installation on designated properties until appropriate approvals are in place.
How do I know if my Society Hill slate roof needs repair or full replacement?
If fewer than 20 percent of slates on your Society Hill roof are broken, missing, or cracked, the original felt underlayment is intact, and the decking shows no evidence of water damage, targeted individual slate repair is almost always the more cost-effective and historically appropriate approach. Ridge cap repointing, flashing maintenance, and individual slate replacement can extend a well-maintained Society Hill slate roof for another 20 to 40 years at a fraction of full replacement cost.
When more than 30 to 40 percent of slates are compromised, or when water has reached the deck and caused rot or delamination, full replacement becomes necessary. Honest Roofing provides a free drone inspection on every Society Hill slate roof with a written repair versus replacement assessment, the cost basis for each option, and guidance on the Commission process where replacement is indicated.
What roofing materials does the Philadelphia Historical Commission approve for Society Hill properties?
For properties with original slate roofing, the Commission generally requires replacement with natural slate matching the original in color, size, texture, and exposure. Asphalt shingles are rarely approved on contributing historic structures in Society Hill. For flat rear sections not visible from the street, TPO, EPDM, and modified bitumen are typically acceptable. Parapet wall caps and any visible flashing material that alters the streetscape appearance may require separate review.
Honest Roofing prepares the material documentation required for Commission review on every Society Hill project where a Certificate of Appropriateness is needed. That documentation includes material samples, manufacturer specifications, and photographic evidence of the existing condition.
