William Penn Roofing has spent 16 years on roofs across Pennsylvania and South Jersey, and Haddonfield sends us a different job than most of Camden County. Plank decking, original slate, copper valley work, and attics never vented to modern standards turn up constantly here. Choosing a roofing contractor in Haddonfield comes down to whether the crew has seen those conditions before or is guessing from the driveway.
Roofs here take a specific beating: nor’easters up the Delaware Valley, humid summers that punish weak ventilation, steady debris from mature street trees, and freeze-thaw cycles that widen a small flashing gap into an active leak by February. We handle residential and commercial work throughout Haddonfield, neighboring Cherry Hill and Collingswood, and out toward Moorestown.
Homeowners across Haddonfield and into neighboring Cherry Hill and Collingswood call us for the same reason: direct communication and a crew that shows up when it says it will. Finished work is in our project gallery.

Project Specialist, Kim was very professional, great follow through and knowledgeable. He took his time to thoroughly explain the new roof installation process and proposal. The on-site project manager, Will kept us updated throughout the project and his crew were punctual and finished on time. Great clean up after job completion. Also, the office manager, Ashley was responsive and very accommodating. Highly recommend.Posted on Google Megan LynchTrustindex verifies that the original source of the review is Google. 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!
Our residential roofing services cover homes of every age, from post-war colonials to properties built long before modern ventilation standards existed.

We complete targeted repairs including shingle replacement, flashing correction, and active leak sealing. Each repair restores protection while extending the life of your existing roofing system.

When repairs no longer make financial sense, we install complete roofing systems with upgraded underlayment and a corrected ventilation path. On older homes that ventilation fix is usually what determines whether the new roof reaches its rated lifespan, and it starts with choosing a ridge vent or an attic fan.

When repairs no longer make financial sense, we install complete roofing systems with upgraded underlayment and balanced ventilation. Every replacement is built for South Jersey’s seasonal weather shifts.

After wind or hail, we stabilize and tarp immediately to stop interior damage. Our storm damage repair includes the inspection reports and photo documentation insurers ask for.
Not every roofing issue requires full replacement. However, these warning signs often indicate deeper structural concerns:
If you notice any of these issues, a professional inspection can clarify your next step.
Roofing projects vary based on structure age, roof pitch, material selection, and underlying decking condition. Clear cost expectations help you plan responsibly.
Many homeowners prefer to explore numbers before scheduling a full replacement. Our online roofing cost calculator estimates a project range from size, material type, and roof complexity.
For larger projects, financing options let you move forward without deferring work that gets more expensive every season.
Storefronts, offices, and mixed-use buildings across Camden County run on low-slope systems that fail through ponding and seam separation long before anything shows from the street. We handle commercial roofing across New Jersey on schedules built around your operating hours.

We address leaks, punctures, seam separation, and drainage issues quickly to prevent interior damage and business interruption.
When a commercial roofing system reaches the end of its lifespan, we install high-performance systems engineered for durability and energy efficiency.

Protective coatings and restoration systems can extend roof life while improving reflectivity and reducing maintenance costs.
We walk the full roof, plus anything you are worried about, and photograph everything. Stains get traced back to a source, since the leak is rarely directly above it. This is where we determine whether you need a repair or a replacement.
You get the photos with a written scope covering materials, labor, ventilation, timeline, and price. We walk it line by line, with no pressure to decide on the spot.
We match the material to the home, the roof design, and the budget, then handle the Borough permit. If your property falls under local design review, we prepare the documentation and build that approval window into your start date.
Landscaping, siding, and walkways get protected first. Once tear-off exposes the decking, anything soft or rotted is photographed and priced before it gets covered back up, and ventilation is corrected during the install.
Debris removal and magnetic nail sweeps across the driveway, lawn, and surrounding areas, which matters on the shared drives and narrow side yards common here. Then we walk the finished roof with you.
We register your manufacturer warranty and hand over the documentation for your records. If anything comes up afterward, you are calling the same company that did the work.
Material choice drives lifespan, maintenance, insulation performance, and long-term value in South Jersey’s fluctuating climate. If you are weighing the two most common options, start with metal roof vs shingles.

A versatile and cost-effective option offering strong wind resistance and broad design flexibility.

Long-lasting and energy efficient, metal roofing resists fire, wind, and impact while providing decades of protection.

Cedar delivers natural character and insulation benefits while standing up to moisture when properly maintained.

Copper accents and roofing systems provide distinctive curb appeal and exceptional durability.

Slate offers premium longevity and timeless architectural appeal when installed by experienced professionals.

TPO membranes provide reflective, energy-efficient protection for flat and low-slope commercial roofs.

EPDM systems offer flexibility and durability in fluctuating temperatures common in South Jersey.

A reinforced, multi-layer flat roofing solution known for strength and weather resistance.
In addition to roofing, we provide exterior upgrades that strengthen your home’s overall protection.

Under a heavy tree canopy, undersized gutters clog fast and back water up under the shingle edge. A properly sized gutter replacement moves runoff away from the roof, siding, and foundation during South Jersey's heavy rain seasons.

New siding improves insulation, weather resistance, and curb appeal while protecting the sheathing beneath, where hidden moisture damage usually starts.

Skylights fail at the flashing, not the glass. Precise skylight installation integrates the curb and flashing into the roof system so the seal holds.

Energy-efficient replacement windows and doors improve comfort, security, and insulation, and correct flashing at every opening keeps water out of the wall.
Estimates here look alike on paper. The difference is who buys the warranty, who is actually on your roof, and who answers the phone in year three.
Haddonfield’s pre-war homes still carry original slate, cedar, and copper. Matching that material is the part most contractors skip, which is why they quote a full asphalt tear-off instead.

Ask any Haddonfield contractor for their 13VH number.
Yes. New Jersey requires Home Improvement Contractor registration rather than a license, and ours is current. We have been working across New Jersey for years and carry full insurance in both states.
Usually. Matching means sourcing tile or shakes that fit the existing profile and weathering, which takes longer than a stock order but keeps the roof consistent. We do the same work on older homes from here up to Princeton.
Noticeably. Constant leaf drop holds moisture against the shingles, clogs valleys, and fills gutters faster than an open lot, and overhanging limbs scrub granules off during wind. Shaded roofs also hold moss. Plan on more frequent gutter clearing and earlier inspections.
Fast enough that homeowners have hired us specifically for it. Active leaks and exposed decking get priority, and emergency tarping goes up first to stop interior damage while the full repair is scheduled.
A failed flashing detail costs a few hundred dollars to correct. Left alone for two winters, it rots the decking beneath it, and now you are paying for framing repair on top of a roof.
Schedule your free inspection and we will show you the photos, outline your options, and give you the honest version even when the honest version is that it can wait.
