If your building has a flat or low-slope roof, EPDM is one of the most reliable solutions out there. This durable EPDM rubber roofing system is built to resist leaks, handle temperature swings, and hold up against the sun. On Top Roofing installs EPDM with expert care so that your flat roof works the way it should for decades.
EPDM stands for ethylene propylene diene monomer—a flexible, rubber-based roofing membrane designed for flat and low-slope roofs. Known for its long lifespan and weather resistance, EPDM can stretch without cracking, even in extreme temperatures. It's also fully waterproof and easy to repair, making it a practical choice for commercial buildings, garages, home extensions, and more.
Why Homeowners Choose EPDM
Watertight by design
EPDM is installed in wide, seamless sheets that create a strong, reliable barrier. With fewer seams, there's less chance for leaks and better protection where it matters most. It’s especially effective on flat roofs, where ponding water can otherwise become a long-term problem.
Durable in shifting weather
Whether temperatures drop below freezing or hit triple digits, EPDM stays flexible and strong. It expands and contracts with your building, which helps prevent cracks and long-term wear. This flexibility helps the roof handle seasonal changes without stress fractures or membrane failure.
Low-maintenance value
Once installed, EPDM doesn’t ask for much. It resists punctures, UV exposure, and ponding water—and if repairs are ever needed, they’re simple and affordable. That means fewer calls to your roofer and more peace of mind over the years.
Our EPDM roofing process
Step 1
Roof inspection and estimate
We begin with a full inspection to assess your structure, drainage, and needs. If EPDM is the right fit, you’ll get a clear, no-pressure estimate.
Step 2
Material planning and prep
We help you choose the right membrane thickness and application method based on your building’s use and long-term goals.
Step 3
Tear-off and surface prep
Our team removes the old roofing material, repairs any damage, and preps the deck to ensure a smooth, lasting bond.
Step 4
Expert installation
We apply the EPDM membrane using industry-proven methods—whether fully adhered, mechanically attached, or ballasted—always sealing every edge and transition for a clean, watertight finish.
Step 5
Final walkthrough
Once the job’s complete, we walk you through the finished roof, answer any questions, and leave the site clean and ready.
