Commercial Flat Roofing: A Comprehensive Guide to TPO Roofing

June 19, 2023

Commercial flat roofing is vital in protecting commercial buildings from the elements. Among the various types of flat roofing available, TPO roofing has gained significant popularity for its energy efficiency, durability, and more.

In this post, we’ll talk all about commercial flat roofing, focusing specifically on TPO roofing. We’ll explore what TPO roofing is, how it works, and how it is installed. We’ll also provide tips for maintaining a commercial flat roof and answer some common FAQs about TPO roofing, as well as how to get a TPO roof of your own for your commercial building.

What is TPO Commercial Flat Roofing?

TPO (Thermoplastic Olefin) is a single-ply roofing membrane that consists of 3 layers: A TPO polymer base, a polyester-reinforced fabric scrim, and a TPO compound top layer. This combination offers several advantages, making TPO roofing an excellent choice for commercial flat roofing. TPO membranes are known for their durability, energy efficiency, and resistance to UV rays, chemicals, and damage.

One of their key benefits is their energy efficiency. TPO roofing reflects sunlight, limiting heat absorption. This means TPO roofing can help reduce energy costs from cooling a building. It is also environmentally friendly compared to other roofing options, as it can be recycled at the end of its lifespan.

How Does TPO Roofing Work?

First and foremost, TPO roofing works by creating a protective barrier on the flat roof, shielding the building from the outside. The membranes used in TPO roofing are heat reflective, which minimizes heat buildup within the structure. They also have water-tight, heat-welded seams, which provide superior strength and durability compared to other flat roofing materials.

In addition to its reflective properties, TPO roofing is also resistant to UV rays and chemicals, making it suitable for various climates and locations. The flexible nature of the TPO membrane allows it to expand and contract with temperature changes without compromising its integrity. This flexibility ensures that the roofing system can withstand extreme weather, including things like high winds and hailstorms. 

How TPO Roofing is Installed

Installing TPO roofing requires precision and expertise to ensure a proper and effective application. It is essential that TPO roofing installation is performed by professionals to ensure your TPO roof lasts.

Before the installation process begins, the flat roof needs to be prepared. This involves cleaning the surface, removing debris or existing roofing materials, and repairing structural issues. Once clean, the flat roof is ready for installation.

Then, the TPO membrane is attached to the roof using either mechanical fasteners, adhesives, and heat welding. The methods chosen depends on the specific requirements of the building. 

How to Maintain Commercial Flat Roofing with TPO

Proper maintenance is crucial for maximizing the lifespan and performance of a commercial flat roof. Here are some essential tips for maintaining TPO roofing:

  1. Schedule Regular Inspections and Maintenance Routines: Schedule regular inspections to identify and address any issues promptly. Establish a maintenance routine that includes checking for damage, clearing debris, and inspecting seams and flashings.
  2. Clean and Remove Debris: Keep the roof surface clean by regularly removing dirt, leaves, and other debris. You can use a soft-bristle broom or non-abrasive cleaning solution to clean and prevent damage to your commercial flat roof.
  3. Address Issues Promptly: If you notice any signs of damage or deterioration, such as tears, punctures, or loose seams, address them as soon as possible. Ignoring minor issues can lead to more significant problems and costly repairs in the long run.
  4. Hire Professional Roofing Services: For any services, such as thorough inspections and repairs, hire a professional. Experienced roofers can identify potential issues and provide expert solutions to ensure the longevity of your TPO roofing.

Commercial Flat Roofing and TPO Roofing: FAQs

1. How Long Does TPO Roofing Last

TPO roofing can last anywhere from 30-50 years depending on proper installation, maintenance, and environmental factors. Some manufacturers have warranties for TPO roofing for up to 50 years. Keeping your roofing clean and getting inspections done every two years is crucial to getting the most out of your roof. Maintaining and promptly repairing your TPO roof will maximize its lifespan.

2. Can TPO Roofing Be Repaired?

Yes, TPO roofing can be repaired. Minor damages like punctures and tears can be patched or welded by a professional roofer. However, it is crucial that repairs be addressed quickly to prevent further damage. Any holes in your TPO roofing can allow moisture into your roof and insulation which can make the damage worse.

3. What Are the Advantages of TPO Roofing?

There are several advantages to TPO roofing, including energy efficiency, durability, UV and chemical resistance, and ease of installation and repair. It was developed as an alternative to PVC flat roofing, and since has become one of the fastest-growing roofing materials.

4. Is TPO Roofing Weather Resistant?

For the most part, yes. It can hold up in extreme cold or warm temperatures, high winds, and even hailstorms. In the case a TPO roof is damaged by weather, it is usually relatively easy to repair. When kept in good condition, you can count on your TPO roof to be water-tight during storms as well.

5. How Much Does it Cost to Install TPO Roofing?
