EPDM vs TPO Roof: Why Property Owners Upgrade to TPO Roofing
Understanding EPDM vs TPO Roofing
Commercial property managers looking to restore or replace an aging EPDM roof often consider TPO roofing material as a viable upgrade. Both materials are widely used in commercial roofing, but TPO roofing has become the preferred choice for many property owners. Understanding EPDM vs TPO and why TPO roofing material is often installed over an EPDM roof during restoration can help property managers make informed decisions.
What Is EPDM Roofing?
EPDM roofing material (ethylene propylene diene monomer) is a type of rubber roofing that has been used in commercial buildings for decades. It is known for its flexibility, ease of installation, and resistance to UV exposure. EPDM roofing is typically black, which can contribute to higher building temperatures as it absorbs heat. While it is cost-effective and has a decent lifespan, EPDM roofing material is often replaced with TPO roofing material when a roofing system reaches the end of its useful life.
EPDM roofing is commonly used on flat or low-slope commercial roofs. It is available in large rolls and can be mechanically fastened, fully adhered, or ballasted. Despite its durability, EPDM roofing can develop issues over time, such as seam failures and shrinkage, which can lead to leaks. While regular maintenance can extend the life of an EPDM roof, many property managers choose to upgrade to TPO roofing for better performance and energy savings.
What Is TPO Roofing?
TPO roofing material (thermoplastic polyolefin) is a newer roofing material that has gained popularity due to its energy efficiency, durability, and performance in extreme weather. Unlike EPDM roofing, TPO roofing is white or light-colored, reflecting more sunlight and reducing heat absorption. Many commercial property managers choose TPO roofing material over EPDM roofing material because of its ability to lower energy costs and extend the TPO roof lifespan.
TPO roofing is made from a blend of rubber and plastic, offering superior resistance to punctures, tears, and chemical exposure. It is also available in wider sheets, which reduces the number of seams and potential leak points. TPO roofing material can be installed using various methods, including mechanical fastening, fully adhered applications, and heat-welded seams. These heat-welded seams create a strong, watertight bond that enhances the roof’s longevity and durability.
Why TPO Is Often Installed Over EPDM
One of the key advantages of TPO roofing material is that it can be installed over an existing EPDM roof in many cases. This eliminates the need for a complete tear-off, reducing labor costs and minimizing disruption to building operations. A proper installation ensures that the new TPO roof adheres securely to the existing EPDM roofing material, providing a seamless and watertight roofing system.
Installing TPO roofing over an EPDM roof requires careful preparation. The existing EPDM surface must be cleaned, and any damaged areas must be repaired before installation. A separation layer, such as a cover board or insulation, is often added to improve adhesion and enhance thermal performance. By choosing to install TPO over EPDM, property managers can achieve a more energy-efficient, durable roofing system without the added costs of a full tear-off.
Advantages of Upgrading from EPDM to TPO
Lower Energy Costs
TPO roofing material is highly reflective, making it a superior option for energy efficiency. Unlike black EPDM roofing, which absorbs heat, TPO roofing reflects sunlight, reducing cooling costs for commercial buildings. This can lead to significant savings on energy bills, especially in warmer climates where air conditioning use is high. Many buildings with TPO roofing experience lower indoor temperatures, reducing strain on HVAC systems and contributing to long-term operational savings.
Increased Durability and Longevity
When comparing EPDM vs TPO, one of the biggest advantages of TPO roofing material is its durability. While EPDM roofing is prone to shrinkage over time, which can cause seam failures and leaks, TPO roofing maintains its structural integrity for a longer period. TPO roofing material is also resistant to punctures, tears, and impact damage, making it a more reliable choice for high-traffic commercial roofs. Additionally, TPO roofing is resistant to chemicals, oils, and grease, making it ideal for commercial properties with rooftop equipment, such as restaurants and manufacturing facilities.
Superior Resistance to Extreme Weather
TPO roofing material offers better performance in extreme weather conditions compared to EPDM roofing material. It can withstand high winds, heavy rain, and hailstorms without degrading as quickly as EPDM roofing. This makes TPO roofing a more resilient option for commercial buildings exposed to severe weather events. TPO roofing is also highly resistant to UV exposure, preventing premature aging and extending the roof’s lifespan.
Fire Resistance
Another key advantage of TPO roofing material is its fire-resistant properties. Many TPO roofing membranes are designed with fire retardants, reducing the risk of fire spreading across the roof. This is an important factor for commercial property managers prioritizing building safety and compliance with fire codes. Compared to EPDM roofing, which can be more vulnerable to fire, TPO roofing provides added protection and peace of mind.
Longer Roof Lifespan
A well-installed TPO roof typically lasts longer than an EPDM roof. While EPDM roofing material generally lasts 20 to 25 years, a TPO roof can exceed 30 years with proper maintenance. This extended lifespan makes TPO roofing a cost-effective choice in the long run, reducing the frequency and expense of roof replacements. Regular inspections and preventive maintenance can further extend the lifespan of a TPO roof, ensuring maximum performance over time.
Making the Right Choice for Your Property
When considering EPDM vs TPO, it is clear that TPO roofing material offers several advantages that make it a preferred roofing material for commercial buildings. Its energy efficiency, durability, weather resistance, and fire protection all contribute to a longer-lasting and more cost-effective roofing solution. Additionally, the ability to install TPO roofing over an existing EPDM roof simplifies the replacement process, reducing labor costs and minimizing downtime.

FAQ: Common Questions About EPDM vs TPO Roofing
1. What is EPDM roofing material?
EPDM roofing material is a synthetic rubber roofing membrane used in commercial buildings. It is known for its flexibility, UV resistance, and affordability. However, many property owners upgrade from EPDM roofing material to TPO roofing material for improved energy efficiency and durability.
2. Can you paint a TPO roof?
Yes, you can paint a TPO roof, but it requires the right type of paint and surface preparation. Acrylic coatings designed for TPO roofing can be applied to enhance reflectivity and extend the roof’s lifespan. However, painting a TPO roof may not be necessary since most TPO roofing material is already highly reflective.
3. How long does a TPO roof last?
A TPO roof typically lasts 25 to 30 years with proper maintenance. The lifespan of TPO roofing material depends on factors such as climate, installation quality, and maintenance. Compared to EPDM roofing, TPO roofing often lasts longer and provides better long-term performance.
4. What is the TPO roofing cost per square foot?
The TPO roofing cost per square foot varies depending on factors such as location, roof size, and installation complexity. On average, the TPO roofing cost per square foot ranges from $5 to $10, including materials and labor. Property managers should get multiple quotes from commercial roofing contractors to determine the best pricing for their specific project.
