Request EPDM QuoteEPDM (Ethylene Propylene Diene Monomer) is a thermoset synthetic rubber membrane that has been used on commercial roofs since the 1960s. It's a single-ply system composed of rubber polymers that create a seamless, flexible layer resistant to UV damage, weathering, and temperature extremes.
EPDM is typically installed in wide rolls (up to 60 feet wide) with seams bonded using adhesive (recommended) or pressure-sensitive tape. Its flexibility makes it ideal for cold climates and buildings with seasonal movement. Repairs are simple—just clean and patch.
Standard Warranty: 25-40 years from manufacturers like Firestone and ContraShear, with excellent track records showing many systems still performing after 50 years.
EPDM is the cost-effective choice for roof replacements and retrofits. Wide membrane rolls reduce installation time and seam complexity, while excellent adhesion to existing surfaces makes overlay applications straightforward.
Assess existing deck condition, insulation compatibility, and drainage. EPDM bonds well to most substrates, making it ideal for overlays and retrofits
Plan seam locations to minimize the number of seams and ensure optimal coverage. EPDM comes in wide rolls (up to 60 feet), reducing installation complexity
Bond seams using either proprietary adhesive (preferred for durability) or pressure-sensitive tape. Adhesive creates stronger, longer-lasting seams
Install EPDM flashing details around HVAC penetrations, roof drains, and wall terminations. EPDM's flexibility accommodates building movement well
Document system with photos, deliver maintenance instructions, warranty details, and design for continued inspections and preventive maintenance
EPDM repairs are the simplest of all roofing systems. Because seams are adhesive-bonded (not heat-welded), patching requires no special equipment. This makes preventive maintenance economical and keeps small problems from becoming expensive emergencies.
Use thermal imaging, moisture meters, and visual inspection to isolate leak source—typically punctures, seam separation, or flashing gaps
Clean the repair area thoroughly with isopropyl alcohol. EPDM repair adhesive requires a clean, dry surface for maximum bond strength
Apply EPDM patch (10-12 inch minimum overlap) using field-splice adhesive tape or liquid adhesive. Simple process, no special equipment needed
Allow adhesive to cure per product instructions (typically 24-48 hours before water exposure). Verify patch adhesion with visual inspection
Photograph repair, provide warranty, and schedule preventive maintenance. EPDM's repair simplicity makes this an economical long-term strategy
EPDM is an excellent choice for new construction projects where cost control and simple coordination are priorities. Wide-roll installation reduces scheduling complexity and seam count, simplifying GC coordination and final closeout.
Submit EPDM system details, seam specifications, and installation method to GC for approval. Highlight simplicity and fast installation schedule
Verify structural deck cleanliness and insulation placement with GC. EPDM's flexibility accommodates minor substrate variations
Work with mechanical trades to locate HVAC, electrical, and plumbing penetrations. Plan flashing details to avoid conflicts
Install membrane, tape/glue seams, and coordinate with following trades. Document progress daily and report any deficiencies to GC
Complete all punch list items, conduct final walkthrough with GC, deliver closeout package including warranty and maintenance plan
Lowest material cost among single-ply membranes, making it ideal for budget-constrained projects without sacrificing performance
Patch repairs are straightforward—just clean, apply adhesive/tape, and wait. No special equipment; temporary fixes are quick and affordable
50+ year track record of successful installations. EPDM systems installed in the 1970s are still performing well today
Adheres well to existing asphalt and other substrates, making it ideal for overlays and retrofits without complete tear-off
EPDM was introduced commercially in the 1960s. Many of those original installations are still performing well today, proving that properly installed and maintained EPDM can outlast its manufacturers' stated warranty periods. This proven longevity makes EPDM a low-risk choice for facilities planning capital budgets.
Because EPDM repairs are simple and affordable ($100-300 per patch), preventive maintenance programs are highly cost-effective. Small repairs address issues before they cause water damage or require larger interventions.
EPDM remains flexible in extreme cold and heat. This flexibility accommodates building movement and reduces stress on seams, extending system life and minimizing the risk of punctures or seam separation.
EPDM's ease of repair makes it ideal for facilities that want to invest in preventive maintenance. Annual or semi-annual inspections, combined with quick patchwork, can extend an EPDM roof's effective life well beyond 40 years.
