EPDM rubber roofing is one of the most durable and reliable commercial roofing systems available, often lasting 30 to 40 years when properly installed and maintained. However, even the best roofing systems can develop problems over time. One issue that building owners occasionally notice is peeling EPDM membrane. While peeling may seem like a cosmetic problem at first, it can quickly lead to leaks and more expensive repairs if left untreated.
At The Flat Roof Guys, we help commercial property owners throughout Wilkes-Barre, Scranton, Hazleton, Bloomsburg, and surrounding Northeastern Pennsylvania communities identify and repair EPDM roofing problems before they become major issues.
What Does Peeling EPDM Look Like?
Peeling typically occurs when sections of the rubber membrane begin lifting away from the roof deck or separate along seams and edges. You may notice:
- Membrane lifting around roof perimeters
- Edges curling upward
- Loose seams
- Areas where adhesive appears to have failed
- Sections of rubber that move when exposed to strong winds
These conditions allow moisture and air to work beneath the membrane, increasing the likelihood of leaks.
What Causes EPDM to Peel?
Several factors can contribute to peeling on a commercial rubber roof.
Aging Adhesives
Over many years, the bonding adhesive used during installation can gradually weaken. Temperature swings, moisture, and UV exposure all contribute to adhesive deterioration.
Improper Installation
If the membrane wasn’t properly adhered during installation, peeling may begin much sooner than expected. Inadequate adhesive coverage or poor surface preparation can reduce the roof’s lifespan.
Ponding Water
Standing water places continuous stress on adhesives and seams. Over time, this constant moisture can weaken the bond between the membrane and the roof substrate.
Wind Exposure
Commercial buildings in Northeastern Pennsylvania regularly experience high winds and severe storms. Wind can gradually lift loose edges, causing peeling to spread across larger sections of the roof.
Why Peeling Should Be Repaired Quickly
Even a small area of peeling creates an entry point for water.
Once moisture reaches the insulation or roof deck, problems often become much more expensive. Wet insulation loses its insulating value, wood decking can deteriorate, and mold may begin developing inside the building.
Because much of this damage remains hidden beneath the membrane, building owners often don’t discover the problem until interior leaks appear.
Can Peeling EPDM Be Repaired?
In many cases, yes.
If the membrane itself remains in good condition, peeling sections can often be professionally cleaned, re-adhered, and sealed without replacing the entire roof. If the affected area has sustained water damage or significant deterioration, localized membrane replacement may be recommended.
An experienced inspection will determine which repair provides the safest and most cost-effective solution.
