What is EPDM Roofing?

EPDM stands for Ethylene Propylene Diene Monomer, a synthetic rubber membrane that has become a go-to material for commercial roofing. Known for its exceptional resistance to weather conditions, EPDM roofing is primarily used for flat and low-sloped roofs.
Its flexible, lightweight nature and impressive lifespan—often exceeding 20 to 30 years—make it a preferred choice for commercial applications. Available in black or white, EPDM roofs are designed to withstand extreme temperatures, UV exposure, hail, and even heavy storms without breaking a sweat.
Whether you’re managing an office building, industrial facility, or retail space, EPDM roofing offers simplified maintenance and reliable protection, ensuring you can focus on your business rather than worrying about leaks or repairs.
Important Features of EPDM Roofing:
- Durability: Resistance to cracking, tearing, and extreme weather conditions.
- Flexibility: It adapts well to fluctuating temperatures and building movements.
- Energy Efficiency: Available in white to reflect sunlight or black to absorb heat, depending on your climate needs.
- Longevity: Typically lasts 20-30 years, with proper maintenance extending its life even further.
6 Key Things to Know About EPDM Roofing
Understanding what EPDM roofing can offer is essential for making an informed decision. Here are the key aspects every property manager or owner should know:
1. Longevity and Low Maintenance
EPDM roofing is designed for long-term performance. With a lifespan of 20-30 years or more, it provides a long-term return on investment. Its smooth, durable surface resists debris, pooling water, and general wear and tear, which translates into fewer repairs and inspections over time.
2. Cost-Effective Solution
For property owners managing large flat roof areas, EPDM is a highly cost-effective option. Initial installation costs are typically lower than other comparable materials like TPO or PVC, and its minimal maintenance requirements mean you’ll save money in the long run.
3. Customizable to Climate
EPDM roofing is available in two color options:
- White EPDM reflects heat, making it ideal for warmer climates and reducing cooling costs.
- Black EPDM absorbs heat, providing additional insulation for colder climates.
This versatility allows property owners to optimize their building’s energy efficiency based on location and seasonal demands.
4. Eco-Friendly and Sustainable
EPDM is recyclable and often manufactured with minimal environmental impact. Its impressive energy efficiency features, such as heat reflection and absorption, further support sustainable roofing practices.
5. Fire and Damage Resistance
EPDM roofs are highly resistant to fire, hail, UV rays, and ozone. This makes them a dependable option for keeping both your commercial property and your tenants safe.
6. Compatibility
EPDM roofing can be installed on new roofs or added as a replacement during a re-roofing project. It’s flexible and can be used on nearly any low-slope roofing system.
The Cost of Installing EPDM Roofing

One of the most common questions property owners have about EPDM roofing is cost. While the total cost depends on several factors, here’s a general idea of what you can expect when considering EPDM for your commercial property:
Factors That Influence Cost
- Size of the Roof: Larger roofs naturally cost more due to the increased quantity of materials and labor required.
- Roof Condition: Existing roof damage or structural issues may add repair costs before installation.
- Insulation Choice: Installing EPDM roofing often involves selecting and adding insulation, which can vary in cost.
- Installation Type: There are three main installation options—fully adhered, mechanically fastened, or ballasted—and each comes with its own costs.
- Labor Rates in Your Area: Regional labor costs can influence the overall price of installation.
Average Cost Estimate
On average, the cost of EPDM roofing installation ranges between $4 to $8 per square foot, depending on the above factors. Here’s a rough breakdown:
- Small Commercial Roof (10,000 sq. ft.): $40,000 – $80,000
- Medium Commercial Roof (25,000 sq. ft.): $100,000 – $200,000
- Large Commercial Roof (50,000 sq. ft.): $200,000 – $400,000
Keep in mind, these costs can fluctuate based on your specific project’s details and location. It’s always advisable to get a professional roofing contractor like Built Right Roofing & Construction to conduct a thorough assessment and provide an accurate estimate.
The EPDM Installation Process
The process of installing EPDM roofing involves several steps to ensure durability and proper coverage. It’s always best to have this done by seasoned roofing professionals for optimal results. Here’s an outline of what to expect:
Step 1: Roof Preparation
Before installation, the existing roof will be inspected for damage or weak spots. Old materials or debris are removed, and the roof surface is cleaned and prepped. If necessary, insulation may be installed at this stage to improve energy efficiency.
Step 2: Measuring and Cutting EPDM
The EPDM membrane is measured and cut to fit your specific roof dimensions.
Step 3: Adhesion or Fastening
There are three common methods for EPDM installation:
- Fully Adhered: EPDM is glued to the roof’s surface using a special adhesive, providing a secure and seamless finish.
- Mechanically Fastened: The membrane is attached using screws and plates, which is quicker and often ideal for larger roofs.
- Ballasted: Large stones are placed over the EPDM membrane to hold it in place. This method is cost-effective but may not be suitable for all structures.
Step 4: Sealing Seams
Once the membrane is in place, the seams are carefully sealed with a specialized tape or adhesive to prevent leaks and ensure structural integrity.
Step 5: Final Inspection
The installation is thoroughly inspected to ensure proper adhesion and sealing. Each step is essential to ensure your roof can withstand various weather conditions and perform well for decades.
How to Decide if EPDM Roofing is Right for You

🎨 Your Roof’s Design
If your building has a flat or low-slope roof, EPDM is an excellent option. Its flexibility and durability make it ideal for these types of structures.
🌍 Climate Considerations
EPDM’s black or white membrane options allow for climate customization. Black EPDM works well in cooler climates, while white EPDM’s reflective properties make it suitable for warmer regions.
