Licensed Roofers Serving Horsham Township and Montgomery County

Roofs here fail on a schedule set by Pennsylvania weather: freeze-thaw through the winter, wind-driven rain in spring, and the heat that bakes south-facing slopes all August. What you want from a roofing contractor in Horsham, PA is a clear read on which of those has already reached your decking, and what it takes to stop it.

William Penn Roofing & Exteriors has handled inspections, leak repairs, storm damage, and replacements across the township since 2008, on split-levels off Welsh Road and flex buildings on Gibraltar Road alike. Our crews run Horsham, Montgomeryville, and Warrington most weeks, so an active leak here usually gets same-day attention.

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!

 Trustindex 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.

 Trustindex 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.

 Trustindex 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.

Residential Roofing Services Designed for Long-Term Performance

Our residential roofing services cover everything from a single slope to a full tear-off, scoped to what the roof actually needs rather than what is easiest to sell. The same construction patterns repeat a few miles west, which is why the roofs we replace in Dresher and Ambler share the same weak points as the ones here.

How Your Roofing Project Runs, Start to Finish

Six steps from the first call to the warranty paperwork.

1. On-site inspection

Our office books the visit, usually within a few days. A project specialist measures the roof, inspects it, and photographs what needs attention.

2. Digital estimate

The proposal reaches your inbox with the scope and payment schedule laid out, so nobody is sitting in your living room waiting on a signature.

3. Digital signature and deposit

You sign online, with the deposit amount spelled out in the proposal rather than raised at the door.

4. Selections, orders, and permit

We confirm shingle line and color, order through our GAF and CertainTeed suppliers, and file the permit with Horsham Township's Code Enforcement Department, which administers the Pennsylvania Uniform Construction Code locally.

5. Scheduling and staging

Materials stage out of our Montgomeryville location, about fifteen minutes up Route 463, so the start date rarely slips waiting on a delivery.

6. Install and closeout

A project specialist is on site at the start of install day and stays with the crew. We walk the finished roof with you, sweep the property with a magnet, and register your manufacturer and workmanship warranties.

Permitting is one of the few things that changes the moment you cross the township line into Fort Washington or Dresher. We file it either way, and the schedule accounts for it.

Repair or Replace: How We Make the Call

Repair usually wins when the damage sits on one slope or one detail and the decking under it is solid. Replacement is the better spend once an asphalt roof passes twenty years, leaks keep surfacing in new spots, or there is already a second layer up there ruling out another overlay.

Either way, you see photos of what we found before you decide.

Understand Roofing Costs Before You Commit to the Work

Accurate pricing depends on the roof itself. Square footage, pitch, the number of existing shingle layers, the condition of the decking, and access around the property all move the final number.

What Actually Moves the Number

Steeper pitches slow the crew and add safety staging, and a second layer of old shingles doubles tear-off and disposal. Our roofing cost calculator gives you a working range before you schedule anything, and the on-site estimate replaces that range with a firm figure.

Hidden Decking Damage and Financing

Soft decking is the most common surprise on older Horsham roofs, so we flag it, price it, and show you the damage before replacing anything. For larger projects, financing spreads the cost into monthly payments.

Commercial Roofing Services for Offices, Retail Buildings, and Multi-Unit Properties

Horsham carries more commercial square footage than most townships its size, much of it in the office parks and flex buildings clustered off Welsh Road and Gibraltar Road. Our commercial roofing work is built around tenants who cannot stop operating while the roof gets fixed.

Roofing Materials Chosen for Durability, Performance, and Curb Appeal

Material choice depends on the structure, the look you want, and how long you plan to own the property. What follows is what we install most often on homes and buildings in this area.

Asphalt Shingle Roofing

The default on most Horsham homes, and the reason is arithmetic: architectural profiles run 25 to 30 years at the lowest installed cost of anything we carry. On shaded north slopes, an algae-resistant line is worth the small upcharge.

Metal Roofing

Where shingles cup and leak early, usually low-slope porches and rear additions, metal solves the problem outright. Tin, steel, and galvanized steel sit mid to upper range on cost and hold 40 to 60 years.

Slate Shingle Roofing

Slate is largely a matching decision. When a home already has it, a synthetic swap reads wrong from the street, and the trade is top-of-range cost against 75 years or more of service.

Cedar Shake Shingles

Cedar buys texture that manufactured products only imitate. Treated shakes hold off pests and rot for 30 to 40 years with upkeep, at the upper middle of the cost range, though humid Pennsylvania summers ask more of them than asphalt.

Copper Roof Install

Bays, dormers, and porch roofs are where copper earns its keep, rather than across a full field. Premium cost, 70 years and up, and a patina no coating reproduces.

Flat Roofing System

Flat and low-slope sections on Horsham’s commercial and multi-unit buildings run on EPDM rubber. Moderate cost, 20 to 30 years, and seam repairs that can be handled in a morning.

Exterior Improvements That Help Protect the Rest of Your Property

A roof is one part of the shell. Gutters, siding, skylights, windows, and failing stucco all affect how a building handles moisture, and a leak blamed on the roof often starts somewhere else.

Why Homeowners and Property Owners in Horsham Choose William Penn Roofing & Exteriors

Storm-chasing crews turn up in Horsham after every hail event and are gone before anyone tests a warranty. We have been working Montgomery County roofs since 2008, out of a Doylestown office and a Montgomeryville branch, and owner David LaSalla still puts his name on the jobs.

What that means in practice:

We cover Montgomery County daily, so a callback in Horsham is a short drive instead of a scheduling problem, and we are still here when a warranty question surfaces years later.

What Horsham Homeowners Ask Before Signing a Roofing Contract

How long does a roof replacement take on a typical Horsham home?

Most of the split-levels, ranches, and colonials here are single-day or two-day jobs once materials are on site. Steeper colonials, slate, and anything that turns up rotted decking during tear-off run longer.

Can a roof be replaced in Horsham during the winter?

Often, yes. Cold weather affects shingle sealing and crew safety more than it affects the roof itself, so we watch the forecast for workable windows and hold off when temperatures or ice make a proper installation unlikely.

Will a new roof come up in Horsham's resale property transfer inspection?

It can. Horsham Township conducts use and occupancy inspections on residential resales, and visible roof or gutter deficiencies are the kind of thing that surfaces during one. Handling it before you list is far cheaper than negotiating it at closing.

Do Horsham HOA communities restrict shingle color or style?

Some do. Several of the newer developments in the township have architectural guidelines covering roof color and profile, so we help you confirm what is approved before ordering material.

Is wind and hail damage on a Horsham roof usually covered by insurance?

Sudden storm damage is typically covered, while wear from age generally is not. The distinction usually hinges on documentation, which is why we photograph everything during the inspection and give you a report you can hand directly to your adjuster.

Don’t Let the Next Storm Be the One That Forces the Decision

Once you know something is wrong up there, every forecast becomes a small stress test. A stain on the ceiling, a repair bill that keeps growing, a room you stop using when it rains.
