Drexel Hill grew up around the trolley line, and the rooftops show it: block after block of stone and brick twins from the 1920s through the 1940s, most with an open front porch and a neighbor sharing the wall. Working on them means matching weathered shingle and slate, handling low porch roofs, and respecting the home attached to yours. Working these gridded streets since 2008, from Aronimink and Drexel Park to Pilgrim Gardens, William Penn Roofing takes on twins, singles, and the duplex conversions that landlords run across the township.
Most calls here open with the same uncertainty: patch it or replace it? On a porch roof or a shared twin slope, the right call can save thousands, so we give you ours after climbing up and actually looking, never off a clipboard quote at the curb.
Homeowners and the landlords who own twins and duplexes around Drexel Hill and the rest of Delaware County have left their take on our work below.

Dave with WPR replaced the roof on our sunroom as well as siding and trim on the front of our house. His crew arrived on time, were professional & cleaned up after they finished. My husband & I are extremely happy with the finished product. We would recommend WPR to anyone needing roofing, trim, siding or gutters. You can trust this company.Posted on Google Ian SmithTrustindex verifies that the original source of the review is Google. I had the pleasure of working with the owner David of William Penn Roofing. He was very helpful with making all of the tough choices with having so many options. The work was completed on time, even in the bad weather. They were very thorough in their cleanup as well. I would highly recommend them for any of your roofing or siding needs! Even there show van as all of the options inside so you can see them in person.Posted on Google MikeTrustindex verifies that the original source of the review is Google. I had roof damage from high winds and reached out for help. Dave responded quickly, arrived promptly, and thoroughly inspected the roof. He identified that the damage was isolated to one area and was able to repair it on the spot. His professionalism, efficiency, and attention to detail were outstanding. I truly appreciated his quick response and quality workmanship. Highly recommend his services to anyone in need of a reliable and skilled roofer!Posted on Google Rich GleesonTrustindex verifies that the original source of the review is Google. Did my roof and banged it out in a single day. Super professional and great communication on the process and timing. Would recommend and use again.Posted on Google Jethro PepeTrustindex verifies that the original source of the review is Google. We recently had William Penn Roofing replace our roof and they did an incredible job from top to bottom. The representative, Kim, did a great job of getting our quote and presenting options to us. The roofing team did a superb 1-day job and cleaned up our yard well. The project manager on the job was there the whole time to answer our questions also! I highly recommend.Posted on Google Sven HedbergTrustindex verifies that the original source of the review is Google. Our roof replacement on 274 East Court Street, Doylestown, was expertly done by William Penn Roofing with a minimum of disturbance to neighbors and traffic. David La Salle’s initial inspection of the failing roof was thorough and quickly followed by a quote. Scheduling and execution were efficient and communication between crew, tenants, neighbors and owners courteous and effective, avoiding all misunderstandings. Supervisors and crew were very professional and friendly and they thoroughly cleaned the job site, side walk and street after completing the job. It is a pleasure to recommend William Penn Roofing, based on quality of work, cost and work crew performance.Posted on Google Joe ETrustindex verifies that the original source of the review is Google. William Penn Roofing did great work on our new roof. Thorough and accurate estimate and scheduled quickly. Roof looks great and they were in and out (and cleaned up) in a day. Whole team was a pleasure to work with. Highly recommend.Posted on Google Elyse GerwickTrustindex verifies that the original source of the review is Google. Really great experience the whole way through with this company. They are excellent with communication, returning calls/emails. Ashley got everything all setup. On the first visit, Kim was very thorough, explaining the whole process, and he had everything with him to be able to show us what we'd be buying (gutter size options, roof colors, and the vents). There was even a folder he left with me with literature and samples I could share with my husband. When the roofers came out they were polite, tidyand did an excellent job with cleanup. It's been 10 days and we have not found a single piece of roofing remnants. The gutters were installed the following day, we opted for 6 inch gutters and downspouts with the gutter guards and couldn't be happier. Again, very professional team and impeccable cleanup. I'd absolutely recommend going with this company for your project and hope to work with them again when we need future work on the house.Posted on Google Patricia KohlheppTrustindex verifies that the original source of the review is Google. William Penn Roofing came to give me a complete inspection of my roof. He explained in detail everything about the roofing from the attic area to the outside. Extremely helpful!
A Drexel Hill roof carries some age. Homes from the 1920s and 30s came with slate or early asphalt, and the second or third roof going on now has to work around dormers, low porch roofs, and the tight valleys where additions meet the original house. The usual trouble spots are worn shingle on the weather side, cracked flashing at the chimney, dried-out pipe boots, and porch roofs that have been quietly leaking behind the gutter line.
Twins change the math. With two homes under one continuous roofline, a failing section on your side can travel into your neighbor’s, so a real fix looks at the whole run, not just your half. The same attached-home stock fills nearby Lansdowne, where we do the same careful work along shared walls.
On these older roofs, the stain on your ceiling and the leak that caused it are often rooms apart. Finding where the water actually gets in comes first; our residential roofing services handle that diagnosis and then the fix, so the same spot does not reappear next spring.

We check the entire roof, shingle and slate fields, porch sections, flashing, chimneys, pipe boots, and ventilation, then lay it out for you in plain language with photos of every problem area.

We put back worn or missing shingles, reflash chimneys and valleys, reseal porch roofs, and swap the cracked pipe boots that quietly sink older Drexel Hill roofs.

Once a roof is past saving, we strip it and build back a full system: new underlayment, ice and water shield, flashing, and shingles chosen to suit a stone-front home.

When wind lifts shingles or a limb comes down, our storm damage repair team gets a tarp up, dries the roof in, and returns for the permanent fix, with photos for the claim. We cover Drexel Hill and neighboring Haverford fast when a line of storms rolls through.
Any one of these is worth a phone call before the next heavy rain:
Our roofing cost calculator puts a ballpark figure in front of you in a couple of minutes. Use it to set expectations, then let an in-person look pin down the real number.
When a replacement is the answer, financing lets you get it done before a hidden leak reaches the framing and plaster. Ask and we will run through the options.
The storefronts and apartment buildings along Burmont Road, Garrett Road, and Lansdowne Avenue mostly sit under flat and low-slope roofs. Our commercial roofing crew services them end to end, across TPO, EPDM, modified bitumen, and coatings, for the building owners and managers who keep them running.

On a flat roof, the usual offenders are ponding water, open seams, and worn membrane. We make targeted repairs to get more life from the roof in place.
When repair stops paying off, we fit the building with a new system matched to its drainage and rooftop use.

A reflective coating can extend a sound flat roof and cut cooling costs. We will tell you honestly whether yours is a candidate.
Reach out by phone, text, or email and we set a time that suits you. A Project Specialist comes to the house, gets on the roof, and goes over the whole thing with you.
You receive a written proposal backed by photos, spelling out the findings and the work. Any questions get answered, and the job proceeds the moment you approve it.
With your deposit down and colors picked, we pull the Upper Darby Township permits and order your materials. About a week before we start, an email confirms the date and what to move or cover.
Your materials and a dumpster land one to two business days ahead of the install. On the day, the Project Manager walks you through it while the crew shields the porch, plantings, and the attached home next door, and most roofs are finished that same day.
We haul off every scrap, run magnetic sweepers across the yard and sidewalk for stray nails, and walk the finished roof with you.
Your final invoice follows about a week later. After it is paid, we file your manufacturer warranty and circle back to make sure everything is dry.
One note worth knowing up front: some conditions only show up after the old materials come off. If damaged decking, failed flashing, or code corrections surface after tear-off, those findings are reviewed with you before any added work moves forward.
On a stone twin, the material comes down to budget, how long you are staying, and keeping the look of the block. Our work spans pitched, specialty, and flat options.

The practical choice on most twins, affordable and stocked in colors that blend with the rest of the row.

A decades-long, wind-resistant option for owners settling in for the long haul.

Natural cedar shake for a stone-front home looking to recover its period character.

A handsome accent over a bay or porch roof that ages into a green patina.

The original material on many older Drexel Hill homes; we repair and match it rather than tearing it off.

A reflective membrane for flat porch roofs, rear additions, and small commercial buildings.

Durable rubber for the low-slope roofs over porches and garages.

A layered flat-roof system for storefronts and buildings with rooftop foot traffic.
A roof only holds if the details around it do. When a job turns up related water trouble, we can handle that too.

Gutters and downspouts sized to push a hard local downpour clear of the foundation.

Vinyl or fiber-cement siding for spots where water has slipped in behind a worn wall.

Skylight installation properly flashed so it brings light, not leaks.

Stucco remediation for cracked, moisture-trapped stucco on older homes.
Window and door installation to replace units that leak air and water.
What keeps the phone ringing here is the honest read on an old roof. On a 90-year-old twin, one company quotes a full tear-off where a targeted repair would do; owner David gets up there himself and tells you which one your roof actually needs.

The owner does the estimate. David is the one up there, so the number you get comes from someone who actually went over the slate, the flashing, and the porch roof, not a salesperson working a commission.

We know attached homes. Twins, duplexes, and porch roofs are everyday work, including the shared-wall and valley details where they leak.

We treat a tight lot with care. We protect the porch and the neighbor's half, then clean up so completely the only trace is a better roof.
In most cases, yes. We can replace your half cleanly, flashing the shared ridge and wall so water cannot track into the adjoining home. If both sides are due, doing them together often costs less per home.
A well-kept slate roof can run 75 years or more, and many here are original. We will tell you whether yours can be repaired and kept or has reached the point where replacement makes more sense.
Yes. Low-slope porch roofs fail differently than the steep main roof, and we flash and seal them as part of the job rather than leaving them as a future leak.
Yes. A lot of Drexel Hill twins are split into rentals, and we work with owners on inspections, repairs, and full replacements scheduled around tenants.
Yes. We are a licensed and insured Pennsylvania contractor, PA HIC #064688, and we pull the proper Upper Darby Township permits for residential and commercial roofing in Drexel Hill.
Water rarely announces itself until the ceiling is already stained, and by then the porch roof or the flashing that let it in has been failing for months. Have us up for an honest look, and you will know exactly where your roof stands, and what it does not need.
Answer a few quick questions and we'll email your estimate.
