EPDM Roofing Systems
A Long-Standing Option for Flat Commercial Roofs
EPDM is one of the more established roofing systems used on flat and low-slope commercial buildings. It’s a synthetic rubber membrane that’s been around for decades. When it’s installed correctly and maintained over time, it can be a reliable, long-lasting option.
We’ve worked on EPDM roofs in all stages—new installations, repairs, and systems that have been in place for years and just need the right attention.
How EPDM Systems Are Installed
EPDM can be installed a few different ways depending on the building.
The most common methods include:
- Fully adhered systems
- Mechanically attached systems
- Ballasted systems
Each approach has its place. What matters most is choosing the right method for the structure and making sure the details are handled properly during installation.
What We See Over Time
EPDM tends to hold up well, but like any roofing system, it has its patterns.
Over time, we commonly see:
- Seams that begin to separate
- Areas where the membrane has shrunk slightly
- Punctures from foot traffic or equipment
- Flashing that needs to be resealed
In many cases, these are manageable issues—especially if they’re caught early.
New Installation & Replacement
We install EPDM systems for both new construction and full roof replacements.
When we’re putting in a new system, the focus is on getting the details right—seams, penetrations, drainage, and how the membrane is secured across the roof.
Those are the areas that tend to determine how the roof performs years down the line.
If you’re replacing an existing roof, we’ll look at how the building is used and whether EPDM is the right fit compared to other systems.
Repair & Restoration Options
One of the advantages of EPDM is that it’s usually repairable.
If the membrane is still in good condition overall, we can often:
- Repair seams
- Patch punctures
- Reseal flashing and penetrations
In some cases, coatings can be used to help extend the life of the system, depending on its condition.
If the roof is showing widespread wear or has reached the end of its lifespan, we’ll walk through that with you and talk through next steps.
Where EPDM Works Best
EPDM is commonly used on:
- Office buildings
- Warehouses
- Schools and municipal buildings
- Retail spaces
It’s a practical option for flat roofs where flexibility and durability over time are important.
