What You Need To Know About Flat Roof Systems

What is a flat roof system? Commercial buildings often have a roof with no slope, rather than a roof with a steep slope. This type of roof, which is known as a flat roof, is available in a few materials.

Knowing which flat roof system would work best for your commercial building involves learning more about different material options. Keep the following in mind to help you choose the right material for your building’s flat roof.


Thermoplastic polyolefin (TPO) roofs provide a cost-effective flat roof option for commercial property owners. The installation process for these roofs is relatively easy, which helps keep labor costs down. TPO roofs are also likely to last for many years, since they are more resistant to algae growth, punctures, and other sources of damage.

TPO roofs offer improved energy efficiency, which helps keep cooling costs down in Central Florida. However, these roofs sometimes have difficulty handling excessive heat. Some also have a laminate layer on top which can develop cracks or weaknesses.

Modified Bitumen

Modified bitumen roofing systems have a single-ply design. These roofs are made up of polymers, fiberglass or polyester, and asphalt bitumen. Modified bitumen flat roofs for commercial buildings are typically resistant to leaks, UV rays, and heat, which allows them to last for several years.

Modified bitumen has a few drawbacks to consider, such as a shorter lifespan compared to other flat roof materials. These roofs can also produce a foul odor after being installed, especially when heat is used. This smell should only last a short time, though.

Owens Corning DeckSeal Self-Adhered

This type of flat roof material is available in 2 or 3 ply systems, which provide superior protection for commercial properties. These roofs are available in a wide range of colors as well, which can enhance the appearance of a commercial building. The DeckSeal roofing system features a dual compound formulation to help reduce the risk of damage and provide durability.

A possible drawback to the Owens Corning DeckSeal Self-Adhered roof system is improper installation. However, you can avoid this by having a professional local roofer in Central Florida install this flat roofing system on your commercial building.If you need more information on flat roof systems for commercial buildings, please contact Alan’s Roofing in Central Florida.
