What Is the Best Commercial Roofing Material?

Best Commercial Roofing Material

Your commercial roof is an invaluable investment. Even a small leak in a roof membrane can quickly become a costly repair. If you’re concerned with your current roof or are looking for the best roofing materials or roof systems recommended by commercial roofers, compare each of these popular options to determine the best course of action for your commercial property.


One of the most common roofing materials available is PVC, or polyvinyl chloride. PVC roofing has a number of advantages over other roofing materials, particularly when it comes to fire or water concerns.

PVC roofs are one of the most fire retardant options available for commercial roofing. While other roofing materials are prone to fire damage or even encouraging the spread of flames, PVC self-distinguishes flames. It’s also a very popular option for its long-lasting waterproofing. Even in extreme weather, PVC is a durable and dependable option.

Of course, all these premium features come at a cost. PVC is one of the most costly commercial roofing options, so if you don’t have the upfront capital for this investment then you may want to consider another option.


Another chemical compound, EPDM, or ethylene propylene diene methylene, is a durable synthetic rubber that is stretchable, affordable and works well in a variety of extremely  cold temperature situations. EPDM roofing isn’t insulating on its own but can be a great water barrier if you’re concerned with heavy amounts of rain or snow. It’s typically used on a flat or low-sloped roof.

However, EPDM is prone to cracking and leaking in extremely hot environments. If you live in a warmer climate that has higher temperatures and longer periods of direct sunlight, EPDM may not be the right choice.

Metal Roofing

One of the most affordable options, metal roofing is easy to install, offers reasonable protection and is a great way to get your commercial building up and running. Metal sheets are secured and sealed with fasteners, caulk and coating to create a weather-tight barrier.

Unlike other commercial roofing systems, metal roofing can easily be retrofitted. If you have an existing metal roof and are considering upgrading to PVC or another roofing material, a professional roofing company can add a new roof on top of your existing one. This option gives you all the advantages of having a new roofing material but protects your roof-line in the event of a sudden thunderstorm in the middle of installation.

Modified Bitumen

Similar to asphalt roofing, modified bitumen is another option that is easy to repair. Modified bitumen roofing has been used for more than 30 years and is a combination of asphalt, fillers and polymers.

The main advantage of modified bitumen is the ease of maintenance. Should your roof begin to leak, crack or otherwise need repairs, a professional roofing contractor can easily patch the damaged section of your roof without replacing an entire sheet of material or your whole roof.

Modified bitumen isn’t as durable as other materials. While it can be repaired more easily, it will require more repairs throughout its lifetime. Consider upgrading to a more durable material if you want to invest in less maintenance throughout the years.
