TPO and Metal: A Popular Commercial Roofing Combo

Many commercial buildings will have different types of roofing materials on different parts of their building’s roof. This is often done for aesthetic reasons – especially if parts of the roof will be visible from the ground.

In central Texas, we see many commercial buildings that rely on thermoplastic polyolefin (TPO) to protect the flat parts of their roof and then choose standing seam metal to protect the sloped portions of their roofs. The two make the perfect combination for protection, durability and beauty. Here’s why:


A TPO roofing system for the flat or low-slope portions of the roof is a popular choice because of its energy efficiency. It is a highly reflective material that helps to reduce heat transfer into the building and improve energy efficiency by helping to reduce cooling costs.

It’s a very durable roofing material that can stand up to the harsh weather conditions and hailstorms that we often experience in Texas. TPO is also cost effective and will provide many years of protection for any commercial building with proper care and regular maintenance.


Standing seam metal roofing panels are one of the most popular choices for sloped portion of the roof on commercial buildings. Not only are they visually interesting to look at, but they also come in a wide variety of colors that will complement any building’s style.

Metal roofs are one of the most durable roofing materials available and they are extremely resistant to fire, wind, hail and other weather-related damage. Their highly reflective surface also contributes toward energy efficiency and can help improve indoor comfort of the building.

A properly installed metal roofing system can be expected to perform for upwards of 50 years or even more. They require very little maintenance and add an aesthetic appeal to any commercial building.

Considerations for the installation

While having two different roofing systems on a commercial building can deliver the curb appeal that the building owner desires, it’s more important than ever to have a professional roofing contractor, like Texas Traditions Roofing, who is trained and certified to install the manufacturer’s products. Extra care needs to be taken where the two systems meet to ensure that both systems can work together to keep the building watertight.
