Key Takeaways
- TPO is a great choice for commercial buildings in sunny or hot climates because it’s resistant to UV rays and reflects heat well.
- Bitumen roofing is a long-lasting option for flat or low-slope roofs, especially in areas with rough weather.
- TPO usually has a moderate upfront cost and requires minimal maintenance, while bitumen is cheaper initially but may cost more in the long run.
- TPO is 100% recyclable and a greener choice than bitumen, which has a bigger environmental impact because of how it’s made.
- Apex Restoration & Roofing knows TPO and bitumen roofing systems inside out, helping you choose the best roofing solution for your commercial property.
Roofing Options for Commercial Buildings: TPO vs. Bitumen
Both TPO (thermoplastic olefin) and bitumen have their perks, but the best fit for your property depends on a few things, like durability, cost, energy efficiency, and maintenance needs.
In this guide, we’ll compare TPO and bitumen roofing systems to help you make the right choice for your business.

What is TPO Roofing?
TPO is a single-ply roofing membrane made from a blend of rubber, plastics, and other materials. It’s a popular choice for low-slope commercial roofs because it has excellent protection against UV radiation, water, and high temperatures.
Why TPO May Be Right for You
TPO is a great choice for commercial buildings in sunny or hot climates. It reflects UV rays and heat which helps to reduce cooling costs. Plus, TPO roofs are resistant to algae, dirt, and debris buildup—so they’re low-maintenance, too.
TPO Roofing: What to Consider
While TPO is great for saving energy and money, it can wear out over time if not installed correctly or if it’s exposed to harsh weather. It can also get punctured in areas with a lot of foot traffic, so it needs to be checked and maintained regularly.
What is Bitumen Roofing?
Bitumen roofing—also called modified bitumen—is made from asphalt and rubberized compounds. It’s applied in layers and usually used for flat or low-slope roofs—especially in areas with harsh weather.
Why Bitumen May Be Right for You
Bitumen is ideal for areas with cold or extreme weather because it’s durable, waterproof, and can handle UV radiation well.
Bitumen Roofing: What to Consider
While bitumen roofing is a cost-effective and highly durable option, it does require more maintenance over time compared to TPO. It’s important to regularly check for cracks or damage, and to make sure the seams are properly sealed to avoid leaks.
TPO vs. Bitumen: A Detailed Comparison
Durability
- TPO: UV-resistant, water-resistant, and can handle high temperatures. However, it can get punctured or damaged from heavy impacts.
- Bitumen: Super durable, including in harsh weather. Bitumen can handle extreme temperatures and heavy snow—but keep an eye on the seams to make sure there aren’t any leaks.
Cost
- TPO: Moderate upfront cost with minimal ongoing maintenance.
- Bitumen: Usually cheaper than TPO, but needs more maintenance over time.
Energy Efficiency
- TPO: Its heat-reflective properties make it a great energy-efficient choice, especially in hot climates.
- Bitumen: It tends to soak up more heat than TPO, so it’s not as energy-efficient.
Maintenance
- TPO: Low maintenance, but check for punctures or damage every now and then.
- Bitumen: Needs to be checked regularly, especially to make sure it doesn’t get damaged at the seams and edges.
Environmental Impact
- TPO: Fully recyclable and a greener choice than bitumen.
- Bitumen: While it’s built to last, it has a bigger environmental impact due to the materials used to make it.
| Comparison | TPO Roofing | Bitumen Roofing |
| Durability | Excellent resistance to UV rays, water, and heat | Super durable, great for extreme temperatures |
| Cost | Moderate initial cost with low maintenance($15-$25 per sq ft) | Lower upfront cost but higher long-term maintenance($12-$18 per sq ft) |
| Energy Efficiency | Superior heat-reflective properties | Less energy-efficient compared to TPO |
| Maintenance | Low maintenance with occasional puncture checks | Requires more maintenance, especially at seams |
| Environmental Impact | Fully recyclable, eco-friendly | Larger environmental footprint during production |
Making the Right Choice for Your Commercial Roof
If you’re looking for an energy-efficient, low-maintenance system with great heat-reflective properties, TPO is the way to go. Bitumen is also a reliable and durable option, particularly suited for areas with extreme weather conditions—but requires more maintenance and it’s not eco-friendly.

Frequently Asked Questions (FAQ)
What are the key differences between TPO and bitumen roofing systems?
TPO is a single-ply membrane made from a mix of rubber, plastics, and other materials. It has great UV resistance, water resistance, and high-temperature protection. Bitumen is a layered roofing system made from asphalt and rubberized compounds. It can handle extreme weather conditions and physical impacts.
Which roofing system is more cost-effective for commercial buildings?
TPO roofing is usually affordable upfront and doesn’t require much maintenance down the line. Bitumen roofing tends to be a bit cheaper upfront but requires more maintenance over time, which can increase long-term costs.
How do TPO and bitumen roofs perform in extreme weather conditions?
TPO roofing is ideal for hot climates as it can handle UV rays and high temperatures well, but it can get punctured easily by heavy impacts. Bitumen roofing is super durable and can stand up to extreme weather—including heavy snow and extreme temperatures—but you have to keep an eye on the seams to make sure there aren’t any leaks.
How do I choose between TPO and bitumen roofing for my commercial property?
If you’re looking for an energy-efficient, low-maintenance system with good heat-reflective properties, TPO is a great choice. If you live in an area with extreme weather and need a durable system, bitumen may be a better fit.
