How Long do Different Types of Commercial Roofing Systems Last

The roof is a vital part of your business’s structure. Without a sound roof, water can get in and damage the building and its contents. That’s why you need to make sure your roof does not have leaks or other issues, and you should get to know your roofing system and how to care for it. Cox Roofing, a roofing company in Anne Arundel County, can discuss different types of roofing materials, what would work best for your business, and how long your roofing system is expected to last.

Different Roofing Types

There are several different roofing types, and each one has a different lifespan than the another.


TPO (typical thermoplastic olefin) roofs are usually found on warehouses, malls, or other flat-roofed commercial buildings. These roofs, when properly maintained, can last for 10-20 years on average. Sometimes, when newer, more technologically advanced materials are used, you can get up to a 35-year warranty on TPO roofing.


EPDM (ethylene propylene diene monomer) roofs are also typically found on flat-roofed buildings. These roofs can last up to 30 years. The average lifespan of an EPDM roof is 20-30 years when properly maintained.


Steep-sloped buildings are where you will typically see metal roofs. Metal roofs can come in a variety of metals from aluminum to copper. These study roofs, when correctly installed and maintained, can last up to 50 years.


A slate roof can have a very long lifespan. Slate has been used for centuries, and the average lifespan is 50 years for synthetic products and 100 years for natural slate.

Extending the Life of Your Roof

To make sure your roof performs as expected and to extend the life of your commercial roof, proper maintenance is key. Other ways to increase the lifespan are to use better materials when installing the roof and making sure the design is optimal for long-term use.
