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.

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!
As the best roofing company in Ambler, we offer residential roofing services designed to keep your home protected from the elements.

Trust our roofing contractors to conduct detailed inspections, identify hidden trouble spots, and determine whether active leaks, aging materials, flashing failures, or storm damage are affecting the integrity of your roof.

Our skilled contractors handle roof repairs that address damaged shingles, flashing issues, and problem areas before they turn into more expensive interior or structural damage.

When repair is no longer enough, our team can replace your roof system or complete a new roof installation with materials and workmanship designed for long-term protection and curb appeal.

When storms hit, our roofing contractors are ready to respond quickly with repairs and emergency protection. More serious storm damage can be addressed before it leads to deeper structural problems.
A professional roofing project should feel organized from the beginning, not confusing or rushed. In most cases, the process includes:
Good communication matters at every stage. You should know what work is being completed, what your property may need during the job, and whether related items like gutters, flashing, skylights, or ventilation should be addressed at the same time.
Some roofing problems are easy to spot, while others build slowly until the damage reaches the attic, insulation, or interior ceilings. Common warning signs include:
Catching these issues early usually gives you more repair options and helps avoid more expensive structural work later.
A professional inspection helps determine whether a repair will restore the roof or whether a replacement offers greater long-term reliability.
Project pricing can vary based on roof size, material choice, existing damage, and labor requirements. Using a roofing calculator can help you set more realistic expectations before moving forward.
For larger repairs or full replacements, financing options can make it easier to move ahead with the work before smaller problems become more expensive.
Our commercial roofing services extend to commercial properties in Ambler, PA as well. We provide durable solutions that help protect buildings, tenants, equipment, and day-to-day operations.

From active leaks to membrane damage and failing seams, our team handles commercial roof repairs that restore performance and help prevent larger disruptions to your property.
If your commercial roof has reached the point where repairs are no longer cost-effective, we can complete a full replacement with careful planning, strong workmanship, and minimal disruption to your operations.

For some commercial properties, restoration or protective coating systems can extend roof life, improve waterproofing, and delay the need for a full replacement while still strengthening long-term performance.

Yes. Wind and hail can loosen shingles, damage flashing, or compromise roof penetrations without creating immediate leaks you can see from outside. In many cases, the first visible sign shows up later as moisture stains, insulation problems, or interior water damage.
It often can, but coverage depends on the source of the damage, the age and condition of the roof, and the details of your policy. Storm-related damage is more likely to qualify than wear and tear, which is why documentation and a timely inspection are important.
Many residential roof replacements can be completed in one to a few days, though the exact timeline depends on roof size, pitch, material choice, weather conditions, and whether hidden damage is discovered once the old system is removed. More complex homes or specialty materials may take longer.
In many cases, yes. If the gutters are aging, poorly pitched, or already showing damage, handling both projects together can improve drainage, reduce labor overlap, and help the full exterior system work better as one. It also makes it easier to address fascia, flashing, and water management in the same project.
Flat roof problems are not always limited to the area where the leak shows up inside. Water can travel beneath the membrane, around seams, or through penetrations before it becomes visible. Before moving ahead with repairs, business owners should understand the roof’s age, membrane type, drainage conditions, and whether targeted repair, coating, restoration, or replacement is the smarter long-term decision.
A roof problem rarely stays contained for long. What starts as a minor leak or a few damaged shingles can turn into stained ceilings, insulation issues, and costly interior repairs. If something feels off, this is the right time to have it looked at and get a clear plan before the damage spreads.
