From Borough Permit to Final Inspection, We Handle the Entire Roof Replacement
William Penn Roofing & Exteriors has been the residential roofing contractor Doylestown homeowners call since 2008. GAF Master Elite certification, PA Registration PA064886, and more than 120 five-star reviews sit behind every roof we replace across Bucks County.
We also handle the parts most homeowners do not think about until they are stuck: pulling the borough permit, meeting the tear-off and final inspections, and registering your manufacturer and workmanship warranties before the job closes.

Residential Roofing Services We Offer
Most calls fall into one of a few categories. Whichever one you are in, the same project lead handles it start to finish.
Roof Replacement
Full tear-off, deck inspection, and a new system installed to manufacturer and borough spec. This is the bulk of what we do on homes across the area.
Roof Repair
Leaks, missing shingles, failed flashing, and damaged valleys. When a repair is the right call, we say so instead of selling a replacement you do not need yet.
Storm Damage Roof Repair
Wind and hail rarely damage just one thing. We document the full scope and handle storm damage repairs alongside the insurance process.
Roof Inspections
An on-roof and in-attic assessment with photos, whether you are buying, selling, or trying to decide how many years you have left.
Flat and Low-Slope Roofing
Porches, additions, and dormer connections need membrane systems rather than shingles. We install EPDM, TPO, and modified bitumen on the low-slope sections most homes here have somewhere.
Gutters and Skylights
Drainage and roof penetrations are where most roofs actually start leaking. We handle gutter installation and skylight installation as part of the same roofline rather than sending you to a second contractor.
What a New Roof Costs, and How to Pay for It
Price comes down to square footage, pitch, how many layers have to come off, and what the decking looks like once it is exposed.
Roofing Cost Calculator
Run the numbers yourself with our roofing cost calculator. It takes a couple of minutes and gives you a working range before anyone visits.
Financing
Monthly payment options are available when the timing is wrong for a lump sum, which is often the case when a leak sets the schedule instead of you.
Signs Your Roof Is Near the End
Roofs fail slowly, and most of it shows up years before the ceiling stains. A few Bucks County winters speed it along.
- Curled or cupped shingles. The seal is breaking, and the next windstorm has something to grab.
- Granules in the gutters. Once the protective layer washes off, the shingle is finished.
- Cracked or broken shingles. Usually after a freeze-thaw swing or a wind event.
- Moss, algae, or black streaks. Tree cover keeps north-facing slopes damp, and trapped moisture rots the decking underneath.
- A roof past twenty years. Freeze, thaw, and summer heat in one year age asphalt faster than the warranty suggests.
- Neighbors replacing theirs. Streets around Doylestown went up in the same stretch, so the roofs finish together.
Why Doylestown Homeowners Choose Our Roofing Team
We work from an office in Doylestown and a second location in Montgomeryville. Crews reach Warrington and New Hope in under half an hour, which matters when a leak starts on a Tuesday afternoon.
What stands behind the work:
GAF Master Elite certification. GAF awards this to roughly 2% of roofing contractors in North America. It is also what lets us offer enhanced manufacturer warranty coverage instead of standard material coverage.
CertainTeed Certified Plus, plus Owens Corning and Velux products. You are not locked into one manufacturer's line because it is the only one we are approved to install.
120+ five-star reviews, BBB A+ accreditation, and Google Guaranteed status.
PA Registration PA064886, with full liability and workers' compensation coverage. Ask any contractor for that number and check it.
Permits and inspections handled by us, including both borough inspections a re-roof requires.
One project lead from estimate through final walkthrough. You are not re-explaining your roof to a new person every week.
Our Roof Replacement Process
1. On-Roof Inspection, Not a Driveway Quote
Your project specialist gets on the roof and into the attic, photographs what is failing, and tells you when a repair still beats a replacement.
2. A Digital Proposal You Can Compare
Scope, materials, and pricing in writing, usually with more than one option so the tradeoffs are visible.
3. Seeing the Roof on Your Own House
Preview colors and profiles through GAF Virtual Remodeler, CertainTeed ColorView, or Owens Corning Build Your Roof. We are certified with all three.
4. Property Protection
Tarps over landscaping, shielding for siding and outdoor features, and magnetic sweeps at the end of every work day.
5. Tear-Off and Decking Inspection
The borough caps a home at two roofing systems, so a second layer means a full tear-off. Any decking replacement gets priced with the deck still open.
6. Sealing, Flashing, and Ventilation
Ice and water shield 24 inches inside the exterior wall line to borough spec, new step flashing at every penetration, and ventilation matched to your attic.
7. Inspections, Walkthrough, and Warranty Registration
We schedule both borough inspections, here or out in Newtown, then walk the finished roof with you and register your warranties.
Quality Roofing Materials Built to Last
We install products from GAF, Owens Corning, CertainTeed, and Velux. Material choice gets driven by your roof and your budget, not by the one line we happen to be approved for.
Roofing Systems and Materials We Install
Asphalt Shingles Roofing
Where most homes here land, and for good reason. Architectural asphalt handles freeze-thaw well, comes in profiles that suit both older and newer builds, and runs 20 to 30 years with proper ventilation.
Metal Roofing
Long life, minimal upkeep, and it sheds snow instead of holding it. Worth a look on low-slope additions and porch roofs, where asphalt usually fails first.
EPDM Flat Roofing
A rubber membrane for flat and low-slope sections. Common on the rear additions and enclosed porches a lot of homes around here picked up over the years.
Natural Slate Roofing
Original on many older Bucks County houses. Very long lifespan, naturally fire and moisture resistant, and heavy enough that the framing needs checking before it goes back on.
Cedar Shake Roofing
Natural character and real insulation value, with maintenance expectations to match. A good fit where the look is part of the property’s value.
Copper Roofing
Durable and visually striking, and it develops a patina over time. Usually specified for bay roofs, dormers, and porch roofs rather than a whole house.
Modified Bitumen Roofing
A layered low-slope system that handles sun exposure and foot traffic better than a single-ply membrane.
TPO Flat Roofing
Single-ply membrane that reflects heat and resists wear. A practical, low-maintenance option for flat sections.
Questions Doylestown Homeowners Ask Before They Hire
Do I need a permit to replace my roof in Doylestown Borough?
Yes, once you go past 20% of the roof. Repairs under that threshold do not require one. The borough also inspects twice, at tear-off and at completion. We pull the permit and schedule both.
What if my home is in the Doylestown Historic District?
Exterior changes visible from a public street and over $2,000 need a HARB Certificate of Appropriateness before work begins. A roof replacement on a street-facing slope qualifies. We prepare the submission with you.
Can I put a new roof over my existing shingles?
Only if your home currently has one layer, since the borough caps it at two roofing systems. Even where it is allowed, an overlay hides deck damage and shortens the life of the new shingles.
How quickly can you get here if my roof is leaking right now?
We run crews out of Doylestown and Montgomeryville, so most of Bucks County is a short drive rather than a dispatch from another county. Active leaks get priority over scheduled estimates.
Will homeowners insurance cover a roof replacement in Pennsylvania?
Usually only when the damage is sudden, like wind or hail, rather than the result of age and wear. We photograph and document the damage so an adjuster has something concrete to work from.
Worried About a Roof Problem Getting Worse? Let's Protect Your Home
Water that gets past the shingles does not stay at the roof. It travels into decking, insulation, and drywall, and the number on the invoice grows every week it stays hidden.
If you have spotted a stain, lost shingles after a storm, or you just know the roof is past twenty, get eyes on it now.
