Commercial Roof Performance

Commercial roofs face myriad demands and must perform at an elevated level to protect the buildings they cover. They are subjected to constant exposure to the elements, including harsh sunlight, rain, snow, and fluctuating temperatures. Additionally, commercial roofs often need to accommodate heavy equipment such as HVAC units and withstand foot traffic for maintenance purposes. These roofs must be durable, weather-resistant, and able to maintain their integrity over extended periods. They also play a crucial role in energy efficiency, as they must effectively insulate the building to reduce heating and cooling costs. Overall, commercial roofs must be reliable and long-lasting to ensure the safety and functionality of the buildings they protect.

Types of Commercial Roofing Systems

Several types of roofing are commonly used on commercial buildings. These include:


EPDM stands for ethylene propylene diene monomer. Flat EPDM roofing is both affordable and durable, as it can withstand the elements for decades without becoming damaged. It also reflects radiant heat, so it can help to lower your monthly energy bills. Since this type of roofing is synthetic rubber material, it will not blister, crack, or rot.


Thermoplastic polyolefin (TPO) is a single-ply roofing membrane. TPO roofing offers exceptional performance in all kinds of temperatures. It is up to 80 millimeters thick and is one of the most durable commercial roofing options available. This type of roofing offers exceptional thermal performance and weather protection, as it is resistant to sun exposure, puncturing, tearing, and water damage. It also doesn’t allow for bacterial growth or dirt buildup, so it is much easier to maintain than most other roofing materials.


Polyvinyl Chloride (PVC) roofing is a popular and eco-friendly flat commercial roofing option. It is a single-ply system that can easily withstand a variety of hazards, such as fire, chemicals, and gale-force winds. It is also resistant to dirt, heat, and moisture, so it has a long lifespan. It is also an eco-friendly flat commercial roofing option.

Who Should Complete Your Commercial Roofing Project?

 A commercial roof installation is a major project and investment—and one that shouldn’t be trusted to just anyone. Before choosing a commercial roofing company, you’ll want to ensure it is highly experienced and skilled in commercial roofs specifically. Take into consideration the number of years they have been in business, as well as their reputation and track record.

The Importance of Commercial Roof Maintenance

Commercial roof maintenance is essential for preserving the integrity and longevity of a building’s roof. Regular maintenance helps identify and address minor issues before they escalate into major problems, saving businesses significant costs in repairs or premature roof replacement. It also helps ensure that the roof continues to perform effectively, protecting the building and its contents from water damage, mold growth, and other potential issues. Additionally, proper maintenance can enhance the energy efficiency of a building by ensuring the roof remains properly insulated and sealed, reducing heating and cooling costs.
