In the realm of commercial roofing, two materials stand out as popular choices: Ethylene Propylene Diene Monomer (EPDM) and Thermoplastic Polyolefin (TPO).
Both offer unique advantages and considerations, making the choice between them a crucial decision for property owners. So, in this blog post, we’ll dive deep into EPDM vs. TPO including:
- The characteristics
- Pros and cons
- Cost factors
- Longevity
- Durability
- Energy efficiency
- Selection criteria
- Considerations when hiring a commercial roofing contractor for EPDM and TPO roofing systems
What is EPDM Roofing?
EPDM, short for Ethylene Propylene Diene Monomer, is a synthetic rubber material widely used in commercial roofing applications. It’s known for its exceptional durability, flexibility, and weather resistance. EPDM roofs are typically installed in large, seamless sheets, providing excellent protection against water infiltration.
Pros and Cons of EPDM Roofing
✅ Pros:
- Durability: EPDM roofing boasts impressive durability, capable of withstanding extreme weather conditions, including high winds, hail, and heavy rain.
- Flexibility: Its rubber composition provides EPDM with excellent flexibility, allowing it to adapt to building movements without cracking or tearing.
- Cost-Effective: EPDM roofing is relatively affordable compared to many other roofing materials, making it an attractive option for budget-conscious property owners.
- Easy Repairs: Minor damages to EPDM roofs can often be repaired quickly and inexpensively, extending the roof’s lifespan.
- Longevity: With proper maintenance, EPDM roofs can last up to 30 years or more, providing excellent long-term value for property owners.
❌ Cons:
- Susceptible to Punctures: While durable, EPDM roofing is prone to punctures from sharp objects or falling debris, which can compromise its integrity.
- Limited Color Options: EPDM roofing typically comes in black, limiting design choices for property owners seeking aesthetic variety.
- Not Ideal for High-Temperature Environments: EPDM may experience degradation in extreme heat, affecting its lifespan and performance.
- Requires Professional Installation: While repairs can be DIY-friendly, installing EPDM roofing requires expertise to ensure proper adhesion and sealing of seams.
What is TPO Roofing?
TPO, or Thermoplastic Polyolefin, is a single-ply roofing membrane composed of a blend of rubber and thermoplastics. TPO roofing is renowned for its energy efficiency, ease of installation, and resistance to UV rays. Like EPDM, TPO roofs are often installed in large sheets, minimizing seams and potential leakage points.
Pros and Cons of TPO Roofing:
✅ Pros:
- Energy Efficiency: TPO roofing reflects sunlight, reducing heat absorption and cooling costs during hot weather, making it an environmentally friendly option.
- Easy Installation: TPO roofing is lightweight and can be installed quickly, reducing labor costs and minimizing disruption to building occupants.
- Resistance to Chemicals: TPO membranes are resistant to chemical exposure, making them suitable for industrial environments where chemical spills may occur.
- Variety of Color Options: Unlike EPDM, TPO roofing is available in a variety of colors, allowing property owners to customize their building’s appearance.
- Recyclable: TPO roofing is recyclable at the end of its lifespan, reducing environmental impact and promoting sustainability.
❌ Cons:
- Prone to Shrinkage: TPO roofing membranes may shrink over time, potentially causing seams to pull apart and leading to water infiltration.
- Less Established Longevity: While TPO roofing has been in use for several decades, its long-term durability compared to EPDM is still being evaluated.
- Vulnerability to Tears: TPO roofing can be more susceptible to tears during installation or due to mechanical damage, requiring careful handling.
- UV Degradation: Although TPO is UV-resistant, prolonged exposure to sunlight may cause some degradation over time, affecting its performance and lifespan.
Cost Considerations
EPDM roofing typically costs between $4 to $8 per square foot installed, making it one of the most cost-effective roofing options available. On the other hand, TPO roofing tends to be slightly more expensive, ranging from $5 to $10 per square foot installed. However, prices may vary depending on factors such as the size of the roof, location, and contractor rates.
Longevity and Durability:
Both EPDM and TPO roofing systems offer impressive longevity when properly maintained. EPDM roofs can last up to 30 years or more, while TPO roofs have a similar lifespan, though exact durability may vary depending on environmental factors and maintenance practices. In terms of durability, EPDM excels in withstanding punctures and hail damage, whereas TPO is prized for its resistance to UV rays and chemicals.
Energy Efficiency Comparison:
TPO roofing holds an advantage in terms of energy efficiency due to its reflective properties, which help reduce heat absorption and cooling costs during hot weather. EPDM, while not as inherently reflective, can still contribute to energy savings through proper insulation and ventilation practices.
Ultimately, the choice between EPDM and TPO roofing may depend on climate considerations and energy efficiency goals.
Choosing the Right Roofing Material for You
When selecting between EPDM and TPO roofing, consider the following factors:
- Climate: EPDM may be more suitable for cooler climates, while TPO is ideal for regions with hot summers.
- Budget: Evaluate upfront costs and long-term maintenance expenses to determine the most cost-effective option for your budget.
- Building Design: Consider aesthetic preferences, color options, and architectural requirements when choosing between EPDM and TPO roofing.
- Environmental Impact: Factor in sustainability goals and recyclability when selecting a roofing material that aligns with your environmental values.
- Contractor Expertise: Choose a reputable commercial roofing contractor with experience installing EPDM or TPO roofing systems to ensure proper installation and warranty coverage.
What to Look for in a Commercial Roofing Contractor
When hiring a commercial roofing contractor for EPDM or TPO installation, consider the following criteria:
1) Experience:
Choose a contractor with a proven track record of installing EPDM or TPO roofing systems on commercial properties similar to yours.
2) Certifications:
Verify that the contractor holds relevant certifications and training for installing EPDM or TPO roofing materials.
3) References:
Request references from past clients and review online reviews to gauge the contractor’s reputation and customer satisfaction.
4) Warranty Coverage:
Ensure that the contractor offers comprehensive warranty coverage for both materials and installation workmanship.
5) Communication and Transparency:
Select a contractor who communicates openly, provides detailed project estimates, and keeps you informed throughout the roofing installation process.
