Choosing the right roofing material for your commercial building isn’t just about cost — it’s about making an investment that will last. Different roofing systems have different lifespans, and understanding how long each type typically lasts can help you plan smarter for maintenance, repairs, and future replacement.
At Holthaus Roofing, we work with the best commercial roofing systems available, including industry-leading options like Duro-Last®, and we help businesses maximize the life of their roofs.
Here’s a guide to the average lifespan of common commercial roofing materials.
1. Duro-Last® Roofing Systems
Duro-Last® roofs are known as the “World’s Best Roof®” for good reason. Custom-fabricated for each building, Duro-Last® roofing systems are extremely durable and resistant to leaks, chemicals, and UV damage.
Average Lifespan:
30+ years with proper installation and regular maintenance.
At Holthaus Roofing, we specialize in installing Duro-Last® systems built to deliver long-lasting protection and energy savings.
2. TPO (Thermoplastic Polyolefin)
TPO roofing is a popular choice for commercial flat roofs due to its affordability and energy efficiency. TPO membranes resist UV rays and heat well, but the quality can vary depending on the manufacturer.
Average Lifespan:
20–30 years with regular inspections and maintenance.
Learn more about TPO roofing systems from the National Roofing Contractors Association (NRCA).
3. EPDM (Ethylene Propylene Diene Monomer)
EPDM, often called “rubber roofing,” is known for its excellent weather resistance, especially in colder climates. Properly installed EPDM can perform well over time, although it can be vulnerable to punctures if not protected.
Average Lifespan:
20–25 years, sometimes longer with high-quality materials and preventative maintenance.
4. Metal Roofing
Metal roofing systems are popular for commercial properties that need long-term durability. They resist fire, high winds, and impact, and many modern coatings enhance their rust resistance and reflectivity.
Average Lifespan:
40–60 years when properly installed and maintained.

5. Built-Up Roofing (BUR)
Built-up roofing, or BUR, is made of layers of bitumen and reinforcing fabrics. It’s a durable and time-tested system for flat or low-slope roofs, but it requires more maintenance compared to newer systems.
Average Lifespan:
20–30 years, depending on the number of layers and maintenance quality.
Extending the Life of Your Commercial Roof
No matter which material you choose, proper care is key. Here’s how you can maximize your roof’s lifespan:
- Schedule regular inspections.
- Repair minor damage before it spreads.
- Keep drains, gutters, and rooftop equipment clear and in good condition.
- Address ponding water issues quickly.
- Re-coat surfaces as needed to maintain energy efficiency and waterproofing.
