How Long Does A Commercial Roof Last?
Different types of commercial roofing can last for a number of different years
- Metal: 40-70 years
- PVC: 25 years
- TPO: 25 years
- EPDM: 20-40 years (depending on thickness)
- Modified Bitumen: 10-15 years
- Spray-On Silicone: 20+ years
The lifespan of a commercial roof depends on many different factors that determine how long they will last. As a broad range, commercial roofing systems can last anywhere between 10-70 years depending on the material used, how it is installed, how it is maintained, and which weather conditions the roof will experience.
Metal Roofing
In general, metal roofing systems last the longest with a lifespan between 40-70 years. In fact, metal roofs don’t require much maintenance compared to other materials either. Some factors, such as proper installation, are key to getting the longest time out of a metal roofing system.
PVC Roofing
Another durable option for commercial roofing systems is PVC roofing, which can last upwards of 25 years. Again, this number is provided assuming the roof gets proper installation and routine maintenance.
TPO Roofing
The main attraction of TPO roofing systems are the low cost and high durability. With that being said, you can expect a lifespan of around 25 years with TPO roofing.
EPDM (Ethylene Propylene Diene Monomer) Roofing
As an extremely enduring option, EPDM roofing systems can last in excess of 50 years (depending on material thickness). On average, though, EPDM lasts between 20-40 years. Additionally, EPDM roofing is often less expensive than both PVC and TPO while having many of the same benefits.Â

Modified BitumenÂ
Made with asphalt and filler ingredients, modified bitumen is an older roofing system that has been around longer than the other roofing systems mentioned previously. With this, modified bitumen lasts between 10-15 years on average.

Spray-On Silicone
While a relatively new option in the roofing industry, spray-on silicone has shown to be very durable. Depending on the thickness of the silicone and appropriate maintenance, spray-on silicone roofs can last up to 20 years or more.
