When you own a business, it is important to have adequate protection from the elements. You want your building to be as efficient as possible so that you can save money and run at optimal capacity. One way to ensure this happens is by installing a commercial flat roofing system on your building. These roofs are particularly beneficial because they offer a waterproof surface with an easy-to-maintain design which will help protect your property for years down the road. However, there are many things that you should know about commercial flat roofing before deciding if this option is right for you.

Commercial Flat Roof Types

There are many different types of commercial flat roofing systems, and each has different qualities and specifications. Each type of commercial flat roof has its advantages and disadvantages which you will learn about below.

Built Up Roofing

This type of commercial flat roofing system has been around for years. It is essentially constructed by creating a thick layer of materials on top of the roof which is then compacted together, providing an even surface with excellent water resistance. There are different "layers" to the built-up roofs, but in general, they include asphalt or coal tar, felt paper that provides insulation and protection, and the final layer is the top UV-protection material like gravel or mineral granules.

Pros: Typically has a longer lifespan of 15-20years; is well suited for warmer climates; You can walk on a built-up roof without causing damage.

Cons: In cold climates, there is a risk of ice dams due to the thick nature of the roofing material. It can also be expensive to install depending on the size of your building and many other factors.

Modified Bitumen Roofing

This commercial flat roofing system is quite similar to the built-up roof. The main difference is that instead of heavy gravel or minerals for the final protective layer, modified bitumen uses a strong polymer material. This type of commercial flat roofing system can last upwards of 30 years due to its durability and chemical properties. Like the built-up roof, some modified bitumen roofs are completely waterproof and suitable for any climate.

Pros: Has a longer lifespan than built-up roofs; Has excellent weather resistance and can last up to 30 years; is well suited for any climate; is less expensive than other commercial flat roofing systems such as TPO roofs.

Cons: Requires an experienced installer; Requires regular maintenance to avoid ponding or leakage.

Thermoplastic Membrane Flat Roof (PVC or TPO)

This type of commercial flat roofing system is both strong and flexible, which allows the material to easily adapt to weather changes. The thermoplastic membrane roof can come in either PVC or TPO form, but both are durable and long-lasting (15 - 20 years). This particular type of commercial flat roofing system also has a reflective surface, which can limit heat absorption in areas that are prone to high temperatures.

Pros: Offers excellent UV resistance, flame resistance, and protection against pooling or leakage; has a long lifespan when properly installed; comes in many different colors for aesthetic appeal.

Cons: Expensive upfront cost; requires professional installation.

Rubber Membrane Flat Roof (EPDM)

This type of commercial flat roofing system is very similar to TPO membranes; however, EPDM roofs cost less and require less maintenance. Although this roof is known for its durability, it can also be more susceptible to damage by ultraviolet rays than TPO membranes.

Pros: Less expensive than most other commercial flat roofing systems; comes in many different color options for aesthetic appeal; has a long lifespan.

Cons: Not as durable as TPO membranes; cannot withstand ponding or leakage; requires regular maintenance to avoid damage caused by ultraviolet rays.

Metal Flat Roofing

This type of commercial flat roofing system is made up entirely or partially of metal. Although this is not the most common system, it is one of the most durable and long-lasting. This type can last anywhere from 50 to 100 years with minimal maintenance needed during that time frame. It is not the most aesthetically appealing option because it does have a rather industrial look to it, but if you’re looking for something very low-maintenance, metal roofs are the way to go.

Pros: Very low-maintenance; very long lifespan; will last indefinitely with minimal maintenance.

Cons: Quite expensive upfront cost; requires professional installation.

Green Flat Roof System

A green roof is made up of living plants. This unique, up-in-coming option offers an aesthetically pleasing finish and a lower energy bill. They can even absorb air pollutants! However, this type of flat roof does require a lot more care and maintenance than the others, although it is very simple in comparison to other gardening tasks.

Pros: Aesthetically pleasing; offers environmental benefits such as absorbing pollutants and energy savings; requires little maintenance.

Cons: It may be difficult to install correctly on your rooftop; can cause damage during installation; costs more than other commercial flat roofing systems.

Concrete Flat Roof

This type of commercial flat roofing system is made up either partially or entirely of concrete. This is another option that can last a long time with very little upkeep if any during the lifespan. Although the upfront cost is more expensive than rubber membranes, it does last longer. One of the best things about this type of commercial flat roof is that it has no seams which make them maintenance-free.

Pros: Very low-maintenance; has no seams which make it maintenance-free.

Cons: More expensive upfront cost compared to other flat roofing systems; may have issues with leaks if not installed correctly.

Spray-On Roof Coating

This type of commercial flat roof is made up either partially or entirely of spray foam. It can be applied over either a built-up or modified bitumen system. The spray foam adds a layer that protects ponding or leakage. This type of commercial flat roof can last up to 40 years. It has become very popular recently due to its ease of installation, inexpensive cost, and ability to adhere to difficult rooftop shapes.

Pros: Very cost-effective; Offers excellent protection against pooling or leakage; costs less than TPO membranes; comes in many different colors for aesthetic appeal; Allows for easy roof repair in case of damage.

Cons: Requires regular maintenance to avoid damage caused by ponding or leakage; cannot withstand excessive heat. Requires professional roof installation; not as durable as TPO membranes.
