What Are the Different Types of Commercial Roofs?

There are so many types of roofs on commercial buildings; it’s hard to know exactly which one is right for your structure. From the structure of your building to the weather in your region, there are so many factors that go into determining what kind makes the most sense for you. That’s why C.I. Services is committed to helping our clients not only choose the right kind for their building, but replace, install, and maintain whatever roofing solution they ultimately go with. In this blog, we’ll talk about the different types of commercial roofs available for facilities as well as the pros and cons of each unique model. 

Roofing 101: Choosing the Right Roof

Don’t let the range of options get you confused—finding the right kind of roof for your building isn’t so hard when you have quality information in front of you. The most important distinction you need to make as a consumer is the overall types of roofing, and the different materials that they can be constructed out of. The most common types of roofs are:

Commercial Flat Roofs

Among the most widely-used roofing solutions in the industry, commercial flats are a cost-effective option due to how much less material they need relative to pitched or steep slope options. They can be constructed from any number of materials, including: TPO (thermoplastic polyolefin), PVC (polyvinyl chloride), EPDM (ethylene propylene diene methylene), regular and modified bitumen, and built-up roofing. Commercial flat roofs reduce energy waste, storage for HVAC units, and simplify maintenance and drain cleaning processes. The main disadvantage is that they offer poor drainage. 

Commercial Low-Sloped Roofs

Often found on top of factories, apartment complexes, warehouses, and other industrial buildings, commercial low-sloped roofs allow for seamless water runoff and safe working conditions for workers. They also can be constructed with the same range of materials as commercial flats, but unfortunately don’t handle heavy snow very well. They also have more strict building codes than other models.  

Commercial Metal Roofs 

Not only does this option extend the lifespan of your roof, it’s also far more cost-effective than a standard metal roof replacement. Metal roofs provide optimal protection, eco-friendly retrofitting processes, and simple re-roofing.

What About the Materials?

As we mentioned above, there are different types of materials used to construct various roof models. In this blog, we’ll talk about three of the main ones: TPO, PVC, and EPDM.


One of the more commonly used single-ply roofing materials, building owners frequently choose TPO over alternatives because of its durability, flexibility, and how effectively it can be customized for simple fabrication. It also boasts the ability the reflect heat away from the building thanks to its color membrane. 


If you’re looking for a material that offers maximum longevity without compromising performance, PVC might be the perfect option. PVC roofing materials fire retardant properties and optimal durability make it a good choice for facility owners looking to increase the strength of their roof without compromising on energy efficiency. 


EPDM roofs offer a solid solution for cooler climates with a highly durable protective layer of rubber. However, they also don’t stand up as well to hot weather (the membrane shrinks as the temperature rises), and adhesives and seams can degrade over time. 

Which One is Right for You?

It all comes down to your unique environment—just because your competitors use one solution doesn’t necessarily mean it’s going to be the right fit for your commercial facility. That’s why you need an expert’s touch. For your next commercial roofing system, choose a provider that you can count on every step of the way, from installation all the way through to ongoing repairs and maintenance. At C.I.

We want to help your facility achieve peak efficiency on your own terms; there’s no room for forcing an inadequate solution on a building that’s not fit for it.
