Putting a new roof on your commercial building is a major investment, so naturally, you’ll want it to last. While the up-front costs are an important consideration, you should also think about the regular maintenance expenses and life spans of the materials when deciding which option to choose. Below is an overview of how often some of the most popular commercial roofing materials need to be replaced.

The Lifespans of Commercial Roofing Products

Thermoplastic Polyolefin (TPO)

commercial roofingTPO is an inexpensive, durable commercial roofing material that consists of a single rubber membrane. As one of the most affordable products on the market today, TPO is an extremely popular choice for stores, offices, and other businesses with flat roofs. Some TPO products have lifespans of just 10 years, although the best manufacturers offer materials that can last 20 years or more.

Thermoset (EPDM)

Like TPO, EPDM is an epoxy membrane that protects the roof from damage. However, these products tend to be much more durable, potentially lasting up to 30 or 40 years. Its remarkable longevity makes up for the higher initial cost, which is why EPDM is the leading choice for flat roofs in a variety of industries.

Metal Roofing

When properly maintained and correctly installed, metal commercial roofing may last indefinitely. At the very least, your metal roof should effectively protect your business for 50 years, although it does have to be painted and sealed periodically.
