Newtown homes take a beating from storms, heavy rain, mature tree coverage, and winter freeze-thaw cycles. That wear can loosen flashing, damage shingles, strain gutters, and create leak points around chimneys, skylights, valleys, and roof penetrations.
Since 2008, William Penn Roofing has helped homeowners and property managers throughout Newtown and Bucks County protect their buildings with reliable roofing systems. We are fully licensed and insured, and our work is backed by manufacturer warranties and workmanship protection. Whether you need a targeted repair, a full replacement, or a clear second opinion, our goal is to identify the real issue and recommend the right level of work.
Many roof leaks start around flashing, pipe boots, chimney transitions, skylight seals, valleys, drip edge, or ventilation issues. That is why a roof leak should be diagnosed before it is priced. Replacing a few shingles may not solve the problem if water is entering through another part of the roof system.
Some of the most common issues we find on Newtown roofs include:
You will receive photos, a written scope of work, and clear recommendations, so you understand whether the issue is isolated or part of a larger roof system problem.

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.

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!

When something is wrong with your roof, you want it fixed correctly without paying for work you do not need. We help Newtown homeowners understand what is causing the problem and whether a repair will solve it, or if replacement is the smarter long-term move with our residential roofing services.

We inspect shingles, flashing, chimney lines, pipe boots, drip edge, attic ventilation, and signs of moisture intrusion, then provide photos and a clear breakdown of what needs attention.

We repair leaks, storm damage, flashing failures, skylight trouble spots, and problem areas around roof penetrations.

If your roof is worn out or has widespread damage, we install a new system with underlayment, ice and water shield, decking inspection, and properly sealed penetrations.

If your roof is hit by wind or hail, we provide emergency tarping, temporary dry-in protection, and permanent repairs with photo documentation for insurance.
If you are trying to decide whether your roof needs repair or replacement, these signs can help you know when to schedule an inspection:
A roof repair or replacement is easier to plan when you understand the likely cost range before booking an appointment. Use these tools to get a clearer starting point and decide what makes sense for your home.
Use our roofing cost calculator to estimate your project based on roof size, material choice, slope, and the type of work you may need.
If your roof needs attention but the full cost is not ideal right now, financing can help you move forward sooner instead of putting off needed work.
Commercial properties in Newtown often rely on flat or low-slope systems where seam failures and drainage issues can lead to costly leaks. Our commercial roofing services include repairs, replacements, and restoration work for TPO, EPDM, modified bitumen, and coated roofing systems.

If your roof has leaks, seam separation, membrane damage, or ponding water, we provide targeted repairs that restore performance.
When the roof system is worn out or repairs are no longer cost-effective, a full replacement can be the smartest long-term solution.

Roof coatings can improve waterproofing and reflectivity while extending service life for certain flat roof systems. We will confirm whether your roof is a good candidate before recommending this option.
The right roofing material depends on your roof slope, drainage, budget, property style, and long-term plans. We help you choose a system that fits the building instead of pushing one option for every roof.
Common roofing materials we install include:
Roofing problems are often connected to drainage, flashing, ventilation, and moisture control. When another exterior issue is contributing to roofline damage or water intrusion, we can address it as part of a more complete solution.
Exterior services that support roof performance include:
A good roofing contractor should do more than quote a price. They should explain what is causing the issue, whether repair or replacement makes more sense, how the work will be completed, and how your property will be protected during the project.
