TPO vs EPDM: Selecting the Right Commercial Roofing System in Texas

Selecting the best roofing material for your building is more than just an aesthetic decision—it’s about performance, durability, and energy efficiency. Two of the top contenders for flat commercial roofs are TPO (Thermoplastic Olefin) and EPDM (Ethylene Propylene Diene Monomer), each offering distinct advantages and some trade-offs. In this guide, we’ll explore the differences between TPO and EPDM roofing, how they perform in Texas’s harsh climate, and which will ultimately be the best for your commercial building.

Since both options are widely popular, comparing their key factors is important to make the most informed decision. Let’s explore the details and help you make a smart choice for your business.

What is TPO Roofing?

TPO roofing is a synthetic, single-ply membrane made from a combination of polypropylene and ethylene-propylene rubber. It’s widely used in commercial construction due to its high reflectivity, which makes it an excellent choice for buildings in warmer climates. One of TPO’s standout features is its ability to keep the building cool by reflecting UV rays and heat from the sun, leading to significant energy savings.

Key Benefits of TPO

TPO roofing is an excellent choice for businesses seeking a low-maintenance, energy-efficient roofing system that can handle the heat.

  • Energy-Efficient: TPO is known for its passive cooling roofing properties. The light-colored surface helps reflect the sun’s rays, reducing your building’s cooling costs during Texas’s hot summers.
  • UV and Ozone Resistance: TPO’s superior resistance to UV rays and ozone ensures it can handle the brutal Texas sun, making it a long-lasting roofing solution.
  • Cost-Effective: TPO offers excellent value for commercial properties, balancing affordability, durability, and performance.
  • Environmentally Friendly: TPO is recyclable, helping you achieve green building goals by reducing your environmental footprint.

What is EPDM Roofing?

EPDM is a rubber roofing material that has been a staple in the commercial roofing industry for decades. This material is known for its flexibility, weather resistance, and exceptional longevity. EPDM comes in a variety of thicknesses and is most commonly available in black or dark gray, though lighter-colored options are available for energy-conscious businesses.

Why Choose EPDM Roofing

EPDM is an ideal roofing solution for businesses looking for a flexible and highly resistant roofing system that can withstand the test of time.

  • Durability: EPDM roofing can last over 30 years, with little to no major repairs required. It’s perfect for commercial buildings looking for a long-lasting, low-maintenance roofing solution.
  • Extreme Weather Resistance: EPDM handles extreme heat and freezing temperatures well. In Texas, where temperatures fluctuate drastically, EPDM is flexible enough to expand and contract without cracking.
  • Rain and Storm Protection: EPDM forms a strong, waterproof seal, making it ideal for areas that experience heavy rain and even hail storms, common in Texas.
  • Energy Efficiency: While it doesn’t reflect the sun’s rays like TPO, EPDM has excellent thermal insulation properties, keeping your building cool in the summer and warm in the winter.

Climate Considerations in Texas: Which Roof Can Handle the Heat?

When deciding between TPO and EPDM, it’s important to consider Texas’s unique climate, known for hot summers, occasional hail storms, and harsh winters.

Performance in Texas Heat:

Texas temperatures can often rise above 100°F in the summer, making your commercial roof likely to absorb a lot of heat. TPO roofing comes out on top in this regard because its reflective surface helps keep your building cooler, reducing your air conditioning load. This lowers energy bills, making TPO a smart choice for commercial property owners looking to cut costs.

Rain and Storm Resistance:

EPDM’s rubber membrane offers a high level of protection against heavy rain, hail, and moisture, which is essential in storm-prone regions of Texas. While TPO can also handle rain, EPDM’s waterproof properties make it more resistant to leaks, especially in areas with a lot of rainfall.

Cold Weather Flexibility:

Though Texas doesn’t typically experience extreme cold, some areas can experience freezing temperatures. EPDM has a much higher tensile strength and elongation capacity than TPO, enabling it to adapt to colder temperatures. Its flexibility in freezing conditions allows it to contract and expand without cracking or damaging, making it more suited for areas with fluctuating temperatures.

Durability and Lifespan: How Long Will Your Roof Last?

Durability is paramount in commercial roofing. Let’s look at how TPO and EPDM stack up in terms of longevity and resilience.

With proper maintenance, TPO roofs typically last between 15 to 20 years. The material holds up well against UV damage, but over time, it may experience some wear and tear due to prolonged sun exposure. Regular inspections can extend the life of a TPO roof.

On the other hand, a well-installed and well-maintained EPDM roof can last 30 years or more with minimal issues. Its ability to resist cracking, puncturing, and shrinking gives it an edge in long-term durability.

EPDM offers exceptional durability and minimal hassle for businesses seeking a roofing system with long-term performance. It is the go-to choice for commercial buildings looking for a “set it and forget it” solution.

Energy Efficiency and Insulation: Reducing Your Utility Bills

Reducing energy consumption and improving energy efficiency should be a top priority for any commercial building owner. TPO and EPDM have energy-saving features, but they work differently.

  • TPO’s Energy Efficiency: TPO roofing’s reflective surface helps reduce the amount of heat absorbed by the building, resulting in lower cooling costs during hot Texas summers. It’s a great option for businesses that want to lower their carbon footprint and keep energy costs down.
  • EPDM’s Thermal Insulation: While TPO offers better reflectivity, EPDM excels at thermal insulation. Its thick rubber membrane helps stabilize a building’s interior temperature, reducing reliance on air conditioning and heating systems.

TPO is your best bet if you’re focused on cooling costs and sustainability. However, if you need a roofing system that helps with both insulation and moisture resistance, EPDM provides a balanced approach.

Cost Comparison: Which Option Fits Your Budget?

When it comes to pricing, TPO roofing is generally more affordable upfront than EPDM. However, long-term savings may make EPDM a better investment. Let’s compare the costs:

TPO Roof Cost: TPO roofing generally costs between $3 and $5 per square foot to install. This makes it a cost-effective choice for large commercial properties, especially if you want to maximize your initial budget.

EPDM Roof Cost: EPDM is slightly more expensive, ranging from $4 to $6 per square foot. However, because of its long lifespan and low maintenance, it may be more cost-effective over time.

Environmental Impact and Sustainability

If you’re considering green building options, both TPO and EPDM offer sustainable benefits. TPO is highly recyclable, which can help your business meet its sustainability goals. The energy savings from its reflective surface lower your building’s overall environmental impact.

Similarly, EPDM is also made from recycled materials and can last longer, reducing the need for frequent replacements. Both options help contribute to a more eco-friendly roofing solution, but TPO’s reflective surface provides better energy savings, making it the more sustainable option for businesses focused on reducing their carbon footprint.

Which Roofing System is Right for Your Business?

The decision between TPO and EPDM ultimately depends on your building’s specific needs and your budget.

Choose TPO if:

  • You need an energy-efficient solution that lowers cooling costs.
  • You want a cost-effective roofing system that performs well in hot climates.
  • You need a roofing system that’s easy to install and maintain.

Choose EPDM if:

  • You’re looking for a durable roofing system with a long lifespan.
  • You need moisture resistance for areas with heavy rainfall or storm threats.
  • You want a roofing solution that performs well in extreme heat and cold temperatures.
