EPDM Rubber Roofing

EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber roofing membrane that has protected commercial flat and low-slope roofs since the 1960s. With over 60 years of proven performance in real-world applications, EPDM has established itself as one of the most trusted and reliable roofing materials in the commercial roofing industry.

EPDM membranes are manufactured from ethylene and propylene—compounds derived from oil and natural gas—creating a thermoset rubber material with remarkable dimensional stability. Unlike thermoplastic materials that can be re-melted, EPDM’s cross-linked molecular structure gives it the unique ability to recover and return to its original state after temperature fluctuations, building movement, or severe weather events. This inherent resilience is at the heart of EPDM’s exceptional durability.

EPDM membranes are available in exceptionally wide sheets—up to 50 feet—which dramatically reduces the number of seams required on your roof. Fewer seams mean fewer potential points for water infiltration. The membrane can be installed using fully adhered, mechanically attached, or ballasted methods, with each approach offering specific advantages depending on your building’s structural characteristics and performance requirements.

Key Features of EPDM Roofing:

• Exceptional Longevity—Properly maintained EPDM roofs routinely last 25-50+ years, with documented installations exceeding 40 years of continuous service.
• Outstanding Flexibility—Elasticity exceeds 300%, allowing the membrane to absorb impacts and accommodate building movement without cracking or splitting.
• Superior Weather Resistance—Withstands extreme temperatures from -40°F to 300°F, UV radiation, ozone exposure, and severe weather conditions.
• Proven Track Record—Over 60 years of documented performance in commercial applications worldwide, with long-term weathering studies confirming reliability.
• Wide Sheet Sizes—Available in sheets up to 50 feet wide, minimizing seams and potential leak points across your roof.
• Impact & Hail Resistant—Rubber composition absorbs impacts from hail, falling debris, and foot traffic without puncturing or fracturing.
• Low Maintenance Requirements—Requires minimal upkeep to achieve full service life potential, with simple and affordable repair procedures.
• Environmentally Friendly—Fully recyclable at the end of its service life and manufactured with increasingly sustainable processes.

EPDM Membrane Thickness Options:

EPDM membranes are available in multiple thicknesses to match your durability requirements and budget:

• 45 mil EPDM—Standard thickness suitable for many commercial applications with moderate foot traffic and typical weather exposure.
• 60 mil EPDM—Enhanced thickness providing greater puncture resistance and extended service life for demanding applications.
• 90 mil EPDM—Maximum thickness for superior durability, ideal for roofs with heavy foot traffic, rooftop equipment, or extreme weather exposure.

EPDM has earned its reputation as the “workhorse” of commercial roofing through decades of proven performance. Here’s why building owners and property managers throughout the Ozark region choose EPDM:

1. Unmatched Longevity & Proven Performance

Long-term weathering studies conducted by the EPDM Roofing Association have documented EPDM roofs performing “like new” after 28-32 years of continuous service. Some installations have exceeded 40 and even 50 years when properly maintained. This exceptional lifespan means your investment in an EPDM roof can provide protection across multiple decades—potentially making it the last roof your building will ever need during your ownership.

2. Superior Flexibility & Dimensional Stability

EPDM’s elasticity exceeds 300%, allowing the membrane to stretch and recover without damage. This remarkable flexibility enables the roof to absorb impacts from hail, falling branches, and other debris without fracturing. It also accommodates building movement, settling, and thermal expansion and contraction without developing cracks or splits. In the Ozark region, where structures experience significant thermal cycling between summer heat and winter cold, this characteristic proves invaluable for maintaining watertight protection year after year.

3. All-Weather Performance

EPDM demonstrates excellent resistance across the full spectrum of weather conditions. The material withstands temperature extremes from -40°F to 300°F, maintains its protective properties under intense UV radiation, and resists degradation from ozone exposure and environmental pollutants. Whether facing the intense sunshine of an Ozark summer afternoon, the freezing temperatures of a January night, or the region’s 44+ inches of annual rainfall, EPDM maintains its integrity and continues protecting your building.

4. Easy & Affordable Repairs

When repairs are needed, EPDM is one of the most forgiving roofing materials to work with. Repairs are straightforward using compatible patching materials, primers, and adhesives. Most repairs can be completed quickly by trained technicians without disrupting your business operations. This ease of repair translates into lower lifetime maintenance costs compared to more complex roofing systems.

5. Handles Heavy Foot Traffic

EPDM’s durability makes it ideal for roofs that require regular access. Whether your building needs frequent HVAC servicing, has rooftop equipment requiring maintenance, or sees regular foot traffic for other reasons, EPDM stands up to the wear and tear. The rubber membrane’s inherent toughness resists punctures and abrasion far better than many alternative roofing materials.

6. Installation Flexibility

EPDM can be installed using multiple methods—fully adhered, mechanically attached, or ballasted—providing flexibility to match your building’s structural requirements and budget. The membrane’s lightweight nature (even at 90 mil thickness) places minimal stress on building structures, and installation doesn’t require open flames or hot materials, making it safer for occupied buildings and reducing fire risk during installation.
