EPDM Rubber Roofing:
Reliable Protection That Stands
the Test of Time
Superior Weather Resistance, Low Maintenance, and Long-Lasting Protection for Your Property
EPDM Roofing: A Durable and Weather-Resistant Solution
EPDM (Ethylene Propylene Diene Monomer) roofing is a single-ply rubber membrane designed for durability, flexibility, and long-term performance. Installed in large rolls, it creates a seamless, watertight barrier that reduces the risk of leaks while ensuring quick and efficient installation.
Engineered to withstand extreme temperatures, UV exposure, and harsh weather conditions, EPDM remains resilient across various climates. Its flexible rubber composition expands and contracts with temperature shifts, preventing cracks and structural stress. Additionally, its resistance to ponding water makes it an ideal choice for flat roofs, further extending its lifespan—often reaching up to 50 years with minimal maintenance.
Perfect for commercial, industrial, and residential applications, EPDM roofing provides a cost-effective and reliable solution that delivers lasting protection and long-term savings.
EPDM Roofing Styles
EPDM Roofing Offers Versatile Installation Options to Suit Any Building, Climate, or Performance Need.
Fully Adhered EPDM Roofing
This method secures the EPDM membrane directly to the roof deck using a high-strength adhesive. It provides a smooth, seamless finish that enhances wind resistance and prevents water infiltration. Fully adhered EPDM is ideal for commercial and residential properties in high-wind areas.
- Best for: Maximum durability and wind resistance
- Material Choice: Available in black or white EPDM for energy efficiency
- Benefits: Superior leak protection, strong adhesion, and a long lifespan
Mechanically Fastened EPDM Roofing
This system uses fasteners along the seams to hold the EPDM membrane in place. It’s a cost-effective and reliable option, especially for large commercial buildings. While slightly less wind-resistant than fully adhered systems, it still offers strong waterproofing and easy repairs.
- Best for: Large commercial buildings needing fast, secure installation
- Material Choice: Reinforced EPDM available for extra strength
- Benefits: Quick installation, cost-effective, and easy maintenance
Ballasted EPDM Roofing
In this system, the EPDM membrane is loose-laid and secured with gravel, river rock, or pavers. It’s one of the most economical options and is commonly used on large industrial or commercial buildings. The added weight requires the structure to support the ballast.
- Best for: Large, flat commercial and industrial roofs
- Material Choice: Black EPDM, compatible with ballast materials
- Benefits: Fast installation, cost-effective, and UV-resistant
Self-Adhered EPDM Roofing
This newer style has a pre-applied adhesive backing, eliminating the need for liquid adhesives. It speeds up installation, reduces labor costs, and minimizes VOC emissions. Self-adhered EPDM is great for both new construction and roof replacements.
- Best for: Quick installations and environmentally conscious projects
- Material Choice: Energy-efficient white EPDM available
- Benefits: Faster installation, lower labor costs, and reduced environmental impact
Reinforced EPDM Roofing
Designed for added strength, reinforced EPDM includes a polyester or fiberglass backing for increased puncture resistance. This makes it ideal for high-traffic areas, rooftops with HVAC units, or locations prone to debris impact.
- Best for: High-traffic roofs needing extra durability
- Material Choice: Thicker EPDM membranes (60 mil+), often pre-taped for easier installation
- Benefits: Higher tear resistance, long-lasting performance, and enhanced durability
White EPDM Roofing
Unlike traditional black EPDM, this style reflects sunlight rather than absorbing heat. White EPDM is commonly used in warm climates where reducing cooling costs is a priority. It offers the same durability as black EPDM but provides better energy efficiency.
- Best for: Hot climates and energy-efficient buildings
- Material Choice: Available in self-adhered, fully adhered, or mechanically fastened systems
- Benefits: Reduces heat absorption, lowers cooling costs, and meets energy efficiency standards
EPDM vs. Other Roofing Materials
Choosing the right roofing material involves understanding how it compares to other options in terms of durability, cost, and performance.
-
EPDM vs. TPO Roofing:
TPO (Thermoplastic Olefin) and EPDM are both popular for commercial and residential flat roofs, but they have key differences.
- Durability: EPDM can last 30+ years, while TPO typically lasts 15–25 years.
- Flexibility: EPDM remains flexible in cold weather, reducing the risk of cracking, whereas TPO can become brittle over time.
- Energy Efficiency: White TPO is highly reflective, reducing cooling costs. White EPDM offers similar energy efficiency but is less common.
- Cost: EPDM is generally more affordable per square foot, with lower installation costs.
-
EPDM vs. PVC Roofing
PVC (Polyvinyl Chloride) roofing is another synthetic option for flat roofs, often chosen for its chemical resistance.
- Durability: PVC resists chemical exposure better than EPDM, making it ideal for restaurants or industrial buildings.
- Strength: Reinforced PVC is more puncture-resistant, while EPDM has superior flexibility.
- Weather Resistance: EPDM performs well in extreme temperatures, while PVC handles high winds better.
- Cost: PVC tends to be more expensive due to its strength and longevity.
-
EPDM vs. Built-Up Roofing (BUR)
Built-up roofing (BUR) consists of layers of tar and gravel, offering a traditional approach to flat roofing.
- Longevity: EPDM lasts just as long, if not longer, with less maintenance.
- Weight: EPDM is lightweight, while BUR is heavy and may require extra structural support.
- Installation: EPDM is faster and easier to install compared to the labor-intensive BUR process.
- Maintenance: BUR requires frequent inspections and repairs, while EPDM has fewer maintenance needs.
-
EPDM vs. Metal Roofing
Metal roofing is a durable, long-term solution often used for sloped roofs, but it differs significantly from EPDM.
- Lifespan: Metal roofs can last 40–70 years, compared to EPDM’s 30+ years.
- Weather Resistance: Metal is highly resistant to wind and fire, whereas EPDM offers better impact resistance.
- Energy Efficiency: EPDM absorbs heat unless a white membrane is used, while metal roofing reflects sunlight effectively.
- Cost: EPDM is far more affordable, both in materials and installation.
Why Choose EPDM Rubber Roofing?
With a 30- to 50-year lifespan, EPDM resists cracks, punctures, and UV damage while flexing with temperature changes.
Extreme heat, freezing cold, hail, and heavy rain won’t break EPDM’s durable, rubberized surface.
A smooth, single-ply design prevents debris buildup and minimizes leaks, reducing upkeep.
Black EPDM retains heat; white reflects it. Made from recycled materials and fully recyclable.
EPDM Roofing Installation
The installation process for EPDM roofing is relatively straightforward, making it a popular choice for both new construction and roof replacements. EPDM is available in varying thicknesses, with standard options being 45, 60, and 90 mils. Thicker membranes provide greater durability and puncture resistance.
Common EPDM Installation Methods:
- Fully Adhered: The EPDM membrane is secured with adhesive, providing a smooth, seamless look. This method offers excellent wind resistance and long-term durability, making it ideal for commercial and residential applications.
- Mechanically Attached: The membrane is fastened using screws and plates, ensuring a strong hold. This method is best for larger roofs where additional reinforcement is needed.
- Ballasted: EPDM is loosely laid over the roof and held in place with gravel or pavers. This is one of the most cost-effective installation methods but requires a strong roof structure to support the added weight.
EPDM Roofing Repairs
One of EPDM’s greatest advantages is its ability to be repaired easily if damage occurs. Unlike other roofing materials that require full replacements or extensive work, EPDM can be patched and resealed with minimal effort.
Common EPDM Repair Solutions:
- Patching Small Tears or Punctures: A special EPDM patch and adhesive can be applied over minor tears, restoring the membrane’s integrity.
- Seam Reinforcement: If a seam becomes loose or begins to separate, resealing it with seam tape or adhesive ensures continued protection.
- Addressing Ponding Water Issues: If water accumulates in certain areas, adjusting the slope or installing proper drainage can prevent long-term damage.
- Recoating for Extended Life: In some cases, an additional protective coating can be applied to refresh the membrane’s durability and enhance UV resistance.
EPDM Roofing Maintenance
Although EPDM is known for its low-maintenance nature, regular inspections and preventative care can help maximize its lifespan.
Maintenance Tips for EPDM Roofs:
- Regular Inspections: Checking for cracks, tears, or pooling water at least twice a year helps catch issues early before they escalate.
- Cleaning Debris and Dirt: Keeping the roof clear of leaves, dirt, and standing water prevents damage and mold growth.
- Checking Seams and Flashing: Ensuring all seams, edges, and flashing are intact helps maintain a watertight seal.
- UV Protective Coatings: In high-sunlight areas, a UV-resistant coating can be applied to extend the roof’s longevity and prevent premature aging.
With proper maintenance, EPDM can last well beyond its expected lifespan, providing consistent performance for decades.
