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 Rich GleesonTrustindex 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 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 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 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 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!
Your roof protects everything underneath it. Our residential roofing services focus on longevity, ventilation performance, and preventing costly moisture damage.

We identify leaks, flashing failures, underlayment issues, and ventilation problems before they turn into structural damage.

We replace damaged shingles, correct flashing, and resolve ventilation issues with repairs built for long-term performance.

When repairs are no longer practical, we remove failing materials, inspect decking, install proper underlayment, and complete a full replacement using high-quality roofing systems.

Wind and storm damage can compromise your roofing system quickly. We provide emergency protection and permanent repairs through our storm damage repair services.

For larger roofing projects, financing options may be available to help spread costs over time through our available roof financing programs.
