EPDM (Ethylene Propylene Diene Monomer) roofing has been a top choice for commercial flat roofs across the U.S. for over 50 years. Known for its durability, flexibility, and cost-efficiency, EPDM is a proven performer, especially in climates that see a wide range of weather conditions like Arkansas. In this blog, we’ll explore the benefits, drawbacks, costs, and Arkansas-specific advantages of EPDM roofing systems.
What is EPDM Roofing?
EPDM is a synthetic rubber roofing membrane primarily used on low-slope or flat commercial roofs. It comes in black or white rolls and is available in varying thicknesses (usually 45, 60, or 90 mil). The membrane can be installed in three ways:
- Fully adhered
- Mechanically attached
- Ballasted
Black EPDM absorbs heat, making it ideal for cold climates, while white EPDM reflects sunlight, suitable for warmer regions.
Key Benefits of EPDM Commercial Roofing
1. Long-Lasting Performance
EPDM roofs can last 30–50 years with proper maintenance. The rubber compound is highly resistant to:
- UV radiation
- Thermal shock
- Ozone exposure
- Hail and wind damage
2. Cost-Effective Solution
EPDM is among the most affordable commercial roofing systems to install and maintain. Its simplicity also leads to faster installations and fewer labor costs.
3. Flexibility and Weather Resistance
EPDM remains flexible in extremely hot or cold temperatures. In Arkansas, where summers are hot and winters occasionally bring ice, this thermal adaptability is key.
4. Low Maintenance Needs
Once installed, EPDM requires minimal upkeep. Annual inspections and simple patch repairs can extend its service life for decades.
5. Environmentally Friendly
EPDM is 100% recyclable at the end of its life cycle and typically made using fewer harmful chemicals than some other roofing materials.
Drawbacks to Consider
While EPDM offers many benefits, here are a few considerations:
- Seam Vulnerability: Older EPDM roofs may experience seam separation, especially if poorly installed.
- Puncture Risk: EPDM is durable, but heavy foot traffic or sharp debris can cause punctures.
- Appearance: A plain black membrane may not be as aesthetically pleasing as other roofing materials.
EPDM Roofing vs. TPO and PVC
| Feature | EPDM | TPO | PVC |
| Cost | Lowest | Moderate | Higher |
| Lifespan | 30–50 years | 20–30 years | 20–30 years |
| Energy Efficiency | Moderate (white) | High | High |
| Installation | Simple | Moderate | Moderate |
| Flexibility | Excellent | Moderate | Good |
Why EPDM is Ideal for Arkansas Commercial Buildings
Arkansas’ climate includes hot, humid summers, moderate rainfall, and some winter weather. This means commercial roofs need to withstand:
- High UV exposure
- Occasional ice storms
- Seasonal temperature swings
EPDM’s resistance to UV rays, flexibility during cold snaps, and low maintenance needs make it well-suited for the Arkansas environment.
Installation and Cost Considerations
EPDM roofing typically costs $4 to $8 per square foot installed, depending on:
- Membrane thickness
- Installation method
- Roof condition and size
It’s best to work with a local, experienced roofing contractor to ensure proper installation and weather sealing.
EPDM Maintenance Tips
- Schedule yearly inspections
- Keep the roof clean from debris and branches
- Monitor seams and flashing for signs of wear
- Limit foot traffic or use protective walkways
