TPO Roofing

USA Building Systems offers the latest and most advanced roofing techniques including TPO. Thermoplastic polyolefin (TPO) single-ply roofing membranes are among the fastest growing commercial roofing products and have gained broad industry acceptance for their many performance and installation advantages.  As demand increases for heat-reflective and energy efficient roofing systems, TPO single-ply roofing membranes continue to provide exceptional resistance to ultraviolet, ozone and chemical exposure.

To take advantage of this recent popularity, a growing number of companies have begun offering TPO single-ply membranes. Unfortunately, not all TPO is created equally.

Your building deserves a TPO roofing system provided by the manufacturer that has been at the forefront of TPO research, development and technology since the inception of TPO as a roofing membrane: USA Building Systems


10 Things to Consider When Investing in a TPO Roofing System!

1) Experience and Innovation

Require that your TPO membrane be manufactured by a company with at least 10 years of TPO manufacturing experience.

The TPO used by USA Building Systems has over 45 years of single-ply manufacturing experience.

2) Cool Roof Properties
(Reducing your air conditioning consumption)

Maximize the energy efficiency of your roof and require that the TPO installed on your building meets initial and three-year ENERGY STAR requirements.

Some manufacturers TPO has not been on the market long enough to even meet the three year requirement for an ENERGY STAR qualification.


The TPO we use not only meets ENERGY STAR qualifications, it far exceeds them.

3) Weathering Package (Sunblock for your roof)

Ensure that your TPO roofing system will withstand the highest temperatures and UV exposures by investing in a membrane that can withstand over 60 days at 275 degrees Fahrenheit, without cracking or showing signs of material failure.

The TPO we install is enhanced with a weathering package, and tests to the highest standards in the industry. It features the most dependable, long-term performance characteristics in the industry.

4) Smooth Surface (Keeping the roof clean)

As a white membrane collects dirt, the cost savings associated with having a reflective roof is severely reduced and the higher associated temperatures can accelerate aging.

A smooth surface is the best way to maintain high reflectivity values, so stick with the TPO roof system that offers the best protection against dirt and debris.

Some TPO may have coarse, rough and uneven surfaces that hold dirt and reduce reflectivity.

The TPO we use has a smooth top surface designed to resist dirt, debris, mildew and bacteria build up. This gives you a cleaner, more solar reflective membrane throughout the life cycle of your roof. This is backed with an industry leading reflectivity warranty.

5) Seam Strength

A strong seam is a vital part of any TPO roofing system. Independent tests conducted using ASTM methods consistently show that  TPO membranes exhibit far stronger seams than competing products.

Having a strong seam means better wind uplift performance and fewer leaks and callbacks.

6) Weldability

Why is weldability very important? Improper welds are the most common and costly mistakes made on a TPO roofing system.

Sheets with a narrow window of weldability can lead to improper welds, which can result to leaks in your roofing system. USA Building Systems TPO membranes can be welded at the widest temperature and humidity ranges without having to modify welder settings to compensate for changing climatic conditions.

This leads to greater productivity and more reliable seams.
7) Diversity and Versatility

Ensure you get the optimum solution for your roof, a TPO system that is custom fitted for your roof.

Some manufactures offer TPO in limited thickness, width and color. This condensed product offering restricts your ability to get the perfect TPO membrane for your roofing project. It’s important to have a wide range of diversity and versatility, because no two roofing projects are ever the same.

The TPO membranes installed by us are available in a wide range of thickness, widths, lengths, and colors. This allows us to get a custom, tailored fit for your roofing project.

8) Thickness over Scrim (Thicker is better)

The top ply of your TPO membrane is the first and best defense your building has against harmful solar UV and weather, so be certain your next TPO roof system features an optimal thickness over scrim.

The TPO used by Whitco features a typical thickness over scrim of 23 mils. That’s 11 mils over the required ASTM minimum. Many other TPO membranes narrowly exceed ASTM’s minimum thickness over scrim requirement, which could mean a thinner top ply and less overall protection.

Thicker is better, thickness leads to greater weathering resistance, and protection against solar UV.

9) Warranties (Protection you can truly count on)

Be sure that the company providing your warranty has a well-funded warranty reserve and “No Dollar Limit” total systems warranties.

Some manufacturers may not publish or provide information about their warranty reserve.

With our TPO, you can rest assure that your building will have outstanding warranty protection. USA Building Systems total system warranties, as well as a large warranty reserve, reflect a commitment and ability to address any warranty issue.

10) Prefabricated Accessories

A typical roof can have hundreds of penetrations. Ensure that these pipes, curbs, and other obstructions are properly waterproofed with TPO accessories certified by the TPO membrane manufacturer issuing your warranty.

Many Manufacturers only offer a limited number of accessories, while others carry products that have not been certified for quality.

USA Building Systems offers a countless number of prefabricated and custom made accessories. All of which carry a CFA (Certified Fabricated Accessory) stamp of approval, so that you will know they are manufactured to the highest of standards.
