Coastal Roofing Specialists Serving Avalon and Seven Mile Island
Avalon sits at the wide end of Seven Mile Island, where salt air and winter nor’easters strip years off a roof that would still look new inland. Choosing between roofing contractors in Avalon, NJ comes down to whether the crew builds for that exposure or treats a beach block like an inland subdivision.
We install, repair, and replace residential and commercial systems across Cape May County, from leak diagnosis on a back-bay ranch to full replacement on an oceanfront home a block off the dune line. Every inspection comes with photos, findings, and a written recommendation before anyone talks price, the same standard our New Jersey roofing crews work to statewide.
“Really great experience the whole way through with this company.” Elyse G.

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![]()

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![]()

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![]()

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![]()

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![]()

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![]()

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!
Before and After: Recent Projects Across Cape May County
Photos say more than a spec sheet. These are systems we tore off and rebuilt on shore properties, including the flashing and fastener details that decide whether a coastal roof holds up. Browse the full project gallery to see finished work.
Residential Roofing Built for Shore Conditions

Roof Inspection & Leak Diagnosis
Inspections review shingles, flashing, underlayment, ventilation, and decking to identify active leaks, moisture intrusion, and early signs of failure.

Roof Repair
Repairs address missing or lifted shingles, damaged flashing around penetrations, salt-related corrosion, wind uplift, and persistent roof leaks affecting shore-area homes.

Roof Replacement & New Roof Installation
When a system reaches the end of its service life, replacement restores structural reliability with wind-rated materials, upgraded underlayment, reinforced flashing, and corrosion-resistant components suited for coastal conditions.

Storm Damage Repair & Emergency Tarping
After severe weather, our storm damage repair process starts with temporary stabilization and interior protection, followed by a documented condition report you can hand straight to an adjuster.
Warning Signs Your Avalon Roof May Be Failing
- Repeated leaks after storms
- Curling or cracked shingles
- Soft decking or interior staining
- Granule loss and visible aging
- Storm-related impact damage
One of these on a younger roof is usually a repair. Several across multiple slopes, especially alongside fastener corrosion, usually is not, and our guide to roof repair versus replacement walks through where that line falls.
Understanding Roofing Investment and Payment Options
Roofing Cost Calculator
Many homeowners begin with a realistic estimate using our roofing cost calculator before scheduling an inspection.
Financing
For larger projects such as full replacements, flexible payment solutions are available through our structured roof financing options.
Commercial and Low-Slope Roofing Solutions in Avalon
Our commercial roofing work covers flat roof drainage correction, membrane repair, protective coatings, preventative maintenance planning, and full system replacement throughout Cape May County and surrounding shore communities.

Commercial Roof Repair
We address membrane punctures, seam separation, ponding water, flashing failures, coating breakdown, and active leaks to restore system performance efficiently.
Commercial Roof Replacement
When a system reaches the end of its service life, full replacement using TPO, EPDM, or modified systems ensures long-term durability and code-compliant performance.

Commercial Roof Coating
Roof coatings can extend the service life of certain commercial systems by adding a protective layer that improves waterproofing and energy performance.
Our Roofing Process From First Call to Final Walkthrough
Every project follows the same sequence, so you know what happens next. Shore work adds one variable inland jobs do not have: many Avalon owners are coordinating from somewhere else, around tenants and weather.
1. Free Roof Inspection
A specialist inspects the full system and any area you have flagged, documenting everything with photos so you see what we see. This is where we determine whether you need a targeted repair or a full replacement.
2. Written Scope and Transparent Estimate
You receive a digital estimate covering materials, labor, and scope by email. No pressure to decide on the spot, and we will walk it line by line, in person or by phone if you are off-island.
3. Material Selection and Project Scheduling
We help you select the right system for your home and budget, specifying coastal upgrades like corrosion-resistant fasteners and high-wind underlayment rather than assuming them. Scheduling accounts for weather windows, rental turnover weeks, and street access.
4. Property Protection and Installation
Before work starts, we protect landscaping, siding, and outdoor features. A project specialist is on site through the job, and open sections are dried in and secured before anyone leaves for the day.
5. Final Walkthrough and Cleanup
We complete a full cleanup with debris removal and magnetic nail sweeps across driveways and surrounding areas. Your project manager then walks the finished roof with you.
6. Warranty Registration and Follow-Up
We register both your manufacturer and workmanship warranties and provide the documentation for your records. If something comes up a season later, you are one phone call away.
High-Performance Roofing Systems for Coastal Properties
Materials are selected for wind uplift resistance, corrosion protection, UV stability, and long-term performance in Avalon’s coastal environment where salt air and heavy coastal storms accelerate material breakdown.

Cedar Roofing

Natural aesthetics with proper treatment and installation to withstand coastal exposure.
Copper Roofing

Premium, long-lasting installations with natural weather resistance.
Slate Roofing

Exceptional longevity and durability when properly supported.

Integrated Exterior Improvements That Reinforce Your Roofing System

Gutter Replacement
Effective drainage systems direct water away from roofing edges and foundations. Seamless gutter replacement improves runoff control and reduces long-term moisture issues.

Skylight Installation
Proper flashing and sealing are critical when integrating skylights into a roof system. Professional skylight installation ensures watertight performance and long-term reliability..

Siding Replacement
Durable siding reinforces the building envelope against coastal exposure. Siding installation helps protect underlying sheathing from moisture intrusion.

Stucco Remediation
Moisture intrusion behind stucco can compromise framing and structural components over time. Coordinated stucco remediation helps prevent hidden water damage and long-term deterioration.
Window & Door Installation
Proper sealing around windows and doors helps block wind-driven rain and air infiltration. Professionally integrated window and door installation supports a tighter, more weather-resistant exterior.
Why Avalon Owners Hire Us Instead of Storm-Season Crews

We have been roofing since 2008, hold certification from all three major shingle manufacturers, and bring the same standards we built in Haddonfield and Moorestown to shore work.

Roofing Questions Homeowners Ask Before Repairing or Replacing a Roof
How long does a roof actually last in Avalon's salt air?
How early should I book a replacement before rental season?
Does the bay side of the island wear differently than the oceanfront blocks?
Yes, and the failure modes differ. Oceanfront and near-dune homes take direct wind load and salt spray, so fasteners and flashing go first. Back-bay properties see more humidity-driven problems in the decking and ventilation.
Can you replace a roof on an elevated beach house with tight street access?
Do I need a permit to replace a roof in Avalon, and who pulls it?
Stop Roof Leaks Before They Turn Into Costly Interior Damage
Shore roofs fail in the offseason, when the house is closed up and nobody is there to notice. By the time a tenant or a neighbor calls, water has usually been moving through the decking and insulation for weeks.
An inspection takes about an hour and comes with photos, findings, and a written proposal covering scope, materials, and timeline. No obligation, and no pressure to decide on the spot.
