With its low maintenance requirements and energy efficiency, investing in an EPDM roof can save you money in the long run while providing peace of mind.
Overview of EPDM Roof
EPDM (ethylene propylene diene terpolymer) is a synthetic rubber roofing membrane made from ethylene and propylene, sourced from oil and natural gas. This material is recognized for its durability, cost-effectiveness, and extensive application on low-slope roofs across commercial and residential buildings.
Key Characteristics
- Composition: EPDM consists of ethylene, propylene, and diene, creating a strong and flexible roofing material.
- Thickness and Width: EPDM membranes are available in various thicknesses, typically ranging from 45 mils to 90 mils. Widths vary from 7.5 to 50 feet, allowing customization for diverse roofing applications.
- Colors: EPDM roofing comes in black, white, and other colors, with black and white being the most popular choices.
- Longevity: EPDM roofs can last up to 50 years with proper installation and maintenance. Fully adhered systems typically have an average lifespan of 25 to 35 years, providing long-term performance.
Benefits of EPDM Roof

EPDM roofing offers numerous advantages that enhance its appeal as a roofing solution for residential and commercial properties. The key benefits include exceptional durability and cost-effectiveness.
Durability
EPDM (Ethylene Propylene Diene Monomer) roofing excels in durability.
- Longevity: EPDM roofs last up to 30 years or more with proper maintenance. This longevity hinges on the material’s ability to endure harsh weather conditions, such as intense UV radiation, ozone exposure, and extreme temperature fluctuations.
- Weather Resistance: EPDM roofs resist severe weather, keeping structures safe from heavy rainfall, snow, hail, and extreme temperatures. The material withstands temperatures from -40ºF to over 300ºF, ensuring performance in diverse climates.
- Chemical Resistance: EPDM demonstrates robust resistance to chemicals, making it ideal for industrial settings prone to chemical exposure. Its resilience ensures that facilities maintain their integrity over time, even in challenging environments.
Cost-Effectiveness
EPDM roofing presents a cost-effective option for property owners.
- Installation Costs: Installation costs range from $3 to $6 per square foot, making EPDM an affordable choice, especially for large surfaces.
- Low Maintenance: With minimal maintenance requirements, EPDM reduces ongoing costs. Property owners benefit from the material’s resilience, leading to fewer repairs and replacements over its lifespan.
- Energy Efficiency: EPDM’s energy-efficient properties promote savings on heating and cooling costs. The option of white EPDM roofing enhances energy efficiency by reflecting sunlight, thereby reducing indoor temperatures and energy consumption.
Installation Process

The installation of an EPDM roof involves a series of straightforward steps that ensure longevity and performance. Careful preparation and correct application techniques lead to optimal results.
Preparation Steps
- Clean the Roof Deck: Your first task is to clean the roof deck thoroughly, making it dry and free from debris. Clear any dirt and dust to promote proper adhesion.
- Sand Sharp Edges: Sand any sharp edges present on the roof surface. This step prevents damage to the EPDM membrane during installation.
- Install Insulation (If Necessary): If your project requires additional insulation, apply it at this stage. Insulation improves energy efficiency and roof performance.
- Install Drip Edge and Drip Batten: Place the drip edge and drip batten around the roof perimeter. These components guide rainwater into the gutter system, preventing pooling.
- Roll Back the EPDM Membrane: Start by rolling back half of the EPDM membrane. This exposes the roof surface where adhesion will occur.
- Apply Bonding Adhesive: Using a paint roller, apply bonding adhesive to the exposed roof surface. Ensure even coverage while the adhesive remains wet. It’s vital for the membrane’s secure attachment.
- Reposition the Membrane: Carefully roll the EPDM membrane back into place, aligning it properly. Repeat this method for the remaining sections of your roof surface for complete coverage.
Maintenance Tips

Maintaining your EPDM roof ensures its longevity and efficiency. Follow these key practices for effective care.
Regular Inspections
Conduct inspections of your EPDM roof at least twice a year, ideally in the spring and fall. In areas with extreme weather or after storms, increase inspection frequency. During these inspections, look for debris build-up, such as leaves or branches. Check for proper water drainage and examine edge trims for any damage. Identify cracks, loose parts, or other signs of wear early to prevent costly repairs.
Repair Procedures
Address repair needs promptly to protect your EPDM roof. For minor cracks or holes, use EPDM roof repair tape or liquid sealant designed for rubber membranes. Ensure the surface is clean and dry before applying any repair products. If you notice extensive damage or persistent leaks, consult a professional for comprehensive repair solutions. Regular repairs maintain the roof's integrity and extend its lifespan, ensuring your investment continues to perform well.
Comparison with Other Roofing Materials

Cost Comparison
- EPDM vs. TPO: EPDM offers a lower upfront cost, ranging from $4 to $10 per square foot, compared to TPO which ranges from $5 to $12 per square foot. This makes EPDM an attractive option for budget-conscious projects.
- EPDM vs. Duro-Last: EPDM provides cost-effectiveness during initial installation. Although Duro-Last roofs may last longer and require less maintenance, the overall savings from choosing EPDM can be significant for many property owners.
Durability and Longevity
- EPDM vs. PVC: EPDM roofs boast impressive resilience to harsh weather conditions and UV exposure, enabling them to last between 30 to 50 years with proper care. In contrast, PVC roofs, while highly resistant to chemicals, typically range around 20 to 30 years in lifespan.
- EPDM vs. Modified Bitumen: EPDM membranes withstand extreme temperatures effectively, surpassing modified bitumen roofs, which may show signs of wear or damage in extreme heat or cold after 10 to 20 years.
Maintenance Requirements
- EPDM vs. TPO: EPDM requires minimal maintenance, involving simple inspections and occasional repairs, making it more user-friendly than TPO, which may require more frequent upkeep due to its susceptibility to punctures.
- EPDM vs. Metal Roofing: EPDM roofing systems are generally easier to maintain than metal roofs, which can show corrosion or rust over time, especially in humid environments. The simple repair methods for EPDM contribute to its appeal.
Energy Efficiency
- EPDM vs. TPO: White EPDM provides excellent energy efficiency, reflecting sunlight and reducing cooling costs significantly. TPO offers similar benefits but can vary in performance based on the specific product and installation quality.
