Philadelphia is a rowhouse city, which means flat roofs, shared party walls and neighbours on both sides of most jobs. It also requires two credentials rather than one — HICPA registration with the state Attorney General and a Philadelphia L&I licence. A contractor with only one of those is not cleared to work on your house. This page lists roofers serving Philadelphia.
What Philadelphia roofers handle
Flat and low-slope roofing on rowhouse stock, the dominant work.
Party wall and parapet detailing, where rowhouse roofs actually leak.
Coating and re-coating, the maintenance cycle for flat roofs here.
Roof deck replacement on century-old framing.
Historic district work in the protected neighbourhoods.
Pitched roof work on the outer neighbourhoods where it exists.
Licensing in Pennsylvania
Pennsylvania registers home improvement contractors through the Attorney General’s Office under HICPA.
Anyone performing $5,000 or more of residential home improvement work in a calendar year must register. Registration costs $100 every two years, and the online system has been operational since April 2026.
Three requirements matter to you as a homeowner:
- Minimum insurance of $50,000 personal injury and $50,000 property damage — a floor the state sets, which you can ask to see
- A HICPA-compliant written contract is mandatory, not optional
- Registration is verifiable with the Attorney General’s Office
Philadelphia and Pittsburgh add municipal requirements on top. Philadelphia specifically requires both HICPA registration and a Philadelphia L&I licence for residential home improvement work. A contractor with one but not the other is not cleared to work on your house.
What’s specific to Philadelphia
Two credentials, both checkable. HICPA registration requires minimum insurance of $50,000 personal injury and $50,000 property damage plus a compliant written contract. Philadelphia then requires its own L&I licence. Ask for both, and check the written contract is HICPA-compliant — that is a legal requirement, not a formality.
Rowhouse roofs fail at the party wall. Water enters at the junction with the neighbour, at the parapet cap and at the flashing between them — very rarely in the middle of the roof. Any quote should name what it covers at those junctions.
Your neighbour’s roof is part of your problem. On attached rowhouses, a failure two doors down can track along the party wall. Coordinated work is sometimes the sensible approach, and a contractor experienced in the stock will say so.
Flat roofs live on coatings. Many Philadelphia rowhouse roofs are maintained on a coating cycle rather than replaced outright, which is far cheaper when kept up and far more expensive when neglected.
Historic districts control appearance. Society Hill, Old City and other protected areas govern material and appearance, with approval preceding the permit.
Pricing expectations
Philadelphia figures for 2026, as published by local roofing companies:
- Typical residential replacement: $5,192–$10,986
- Flat roof on a ~900 sq ft rowhome: EPDM $5,500–$8,500, TPO $6,500–$9,500, modified bitumen $6,800–$10,000
- Flat membrane installed: EPDM $6–$9 per square foot, TPO $7–$10, modified bitumen $7–$11
- Pitched, where it exists: three-tab $3.50–$5.00, architectural $4.50–$7.00, slate $15–$30
- Full tear-off surcharge: $1.50–$3.00 per square foot over roofing across one layer, or $1,200–$2,800 per layer removed
- Tapered insulation to fix ponding: $2–$4 per square foot, or $1,800–$4,000
- New roof drain or scupper: $300–$800 each; city permit $200–$400
A Philadelphia rowhome roof is small — typically 800 to 1,400 square feet — which is why the totals here sit well below detached-housing markets even though the per-foot rates do not. The two lines that decide whether a cheap quote stays cheap are the tear-off surcharge, since a roof already carrying layers costs $1,200–$2,800 more per layer to strip, and tapered insulation, which is what stops water standing on a dead-flat roof and is the difference between a membrane that lasts and one that fails early. Neither appears on a quote unless you ask.
These are ranges local roofing companies publish for this metro rather than survey data, so treat them as a bracket to check a quote against, not a price list.
Two contract items: whether the price is a tear-off or an overlay, and how many layers are up there, and whether tapered insulation is included, and what happens at the parapet and party wall.

How this directory helps
Every roofer here is listed with business name, address and phone so you can verify them yourself.
Three questions sort Philadelphia contractors. Ask for both HICPA registration and the Philadelphia L&I licence — you need both. Ask what the quote covers at the party wall and parapet. And confirm the contract is HICPA-compliant, which the law requires.
