When you’re running a business or managing a commercial property, your roof does more than just keep the rain out — it protects your operations, your assets, your employees, and your bottom line. That’s why choosing the right commercial roofing system is one of the most important decisions you’ll make. At Revolve Construction, we specialize in helping business owners across Missouri and Illinois make smart, long-term roofing choices that align with performance goals and budget.
Two of the most widely used flat and low-slope commercial roofing systems today are TPO (Thermoplastic Polyolefin) and EPDM (Ethylene Propylene Diene Monomer). While both materials have proven track records, they offer different advantages when it comes to cost, durability, energy efficiency, and installation.
So, how do you decide which system is right for your property?
Whether you’re planning a new build, replacing an aging roof, or recovering from storm damage, this guide will walk you through the key differences between TPO and EPDM.
At Revolve Construction, we don’t just install roofing systems — we partner with property owners to build solutions that last.
What Is TPO Roofing?
TPO roofing is a single-ply white membrane made from a blend of rubber and plastic. It’s usually heat-welded at the seams and installed in large sheets across flat or low-slope commercial roofs.
Key Features of TPO:
- Bright white surface reflects sunlight
- Heat-welded seams for strong waterproofing
- Resistant to UV rays, dirt, and algae
- Lightweight and flexible
- Energy-efficient
What Is EPDM Roofing?
EPDM roofing is a single-ply black rubber membrane, similar to a big inner tube laid over your building. It’s installed using adhesive or ballasted with stone or pavers.
Key Features of EPDM:
- Long-lasting rubber material
- Seamless or minimal seam options
- Resistant to UV damage and weathering
- Low maintenance
- Cost-effective
TPO vs. EPDM: Side-by-Side Comparison
| Feature | TPO | EPDM |
| Color | White (reflective) | Black (absorbs heat) |
| Energy Efficiency | Reflects heat (cooler building) | Absorbs heat (warmer building) |
| Installation | Heat-welded or mechanically fastened | Adhered or ballasted |
| Cost | Slightly more expensive | Usually more affordable |
| Durability | 15–20 years (with proper care) | 20–30 years (with proper care) |
| Weather Resistance | Excellent UV and chemical resistance | Great for cold climates |
| Best Use Case | Hot climates, energy savings | Cold climates, budget-friendly |
Benefits of TPO Roofing
1. Energy Savings
TPO’s white surface reflects sunlight and helps keep your building cooler in the summer. This can reduce your air conditioning costs and make your building more energy-efficient.
2. Strong Seams
TPO roofs are heat-welded at the seams, which creates a watertight seal that’s less likely to fail compared to glued seams. This is especially useful in areas with heavy rainfall.
3. Lightweight & Flexible
TPO is easier to install on a variety of roof structures. Its lightweight material puts less stress on the building’s frame.
4. Eco-Friendly
Many TPO roofs are recyclable, making them a better choice for environmentally-conscious businesses.
Benefits of EPDM Roofing
1. Budget-Friendly
EPDM is generally more affordable than TPO, both in materials and labor. If you’re looking for cost-effective durability, this might be your best option.
2. Proven Longevity
EPDM has been used in the roofing industry for decades. When properly installed and maintained, EPDM roofs can last up to 30 years.
3. Performs Well in Cold Climates
Black rubber naturally absorbs heat, which can help reduce heating costs during winter months. It’s also less likely to crack in freezing temperatures.
4. Easy Repairs
In case of damage, EPDM is easy to repair with rubber patches or liquid coatings. Repairs can often be done quickly and inexpensively.
Which One Is Right for Your Building?
Let’s help you decide by asking a few simple questions.
1. What’s the climate like in your area?
- If you’re in a hot or sunny climate, go with TPO. Its reflective surface keeps buildings cooler.
- If you’re in a cold climate, EPDM helps retain heat better.
2. What’s your budget?
- EPDM is more cost-effective upfront and easier to install.
- TPO may cost slightly more but can save on cooling costs over time.
3. How important is energy efficiency?
- TPO is ideal for buildings looking to qualify for ENERGY STAR® certifications or LEED points.
- EPDM still offers efficiency, but mainly for heating rather than cooling.
4. Do you need a roof that’s easy to maintain?
- EPDM is easier to patch and repair.
- TPO has stronger seams but might need a professional to fix any issues.
What About Lifespan?
- TPO roofs typically last 15 to 20 years, though newer formulations are improving durability.
- EPDM roofs often last 20 to 30 years with proper maintenance.
Both systems can perform well if installed correctly — the key is choosing a trusted roofing contractor with experience in commercial.
Final Thoughts
There’s no “one size fits all” when it comes to commercial roofing. Both TPO and EPDM offer solid protection, durability, and performance. The right choice depends on your building type, local climate, energy goals, and budget.
