The lifespan of a commercial roof depends on the materials and installation process used. Business owners and building managers need to research different materials available to determine which one is the most durable and will last the longest. They should also consider the roof’s design and shape and how it may affect the types of materials that should be used. 

In this article, you will learn more about the various types of commercial roofing and their typical life spans. Keep reading below.


Asphalt roofing is one of the most popular roofing materials for both residential and commercial buildings. Asphalt is relatively inexpensive and easy to install, making it an excellent option for those on a budget. But how long does an asphalt roof last?

When properly installed and maintained, a low-slope asphalt roof can last anywhere from 15 to 20 years. In comparison, a steep-slope shingle roof can last up to 40 years. Of course, the longevity of the roof depends on several factors.

Ethylene Propylene Diene Monomer (EPDM)

When it comes to commercial roofing, EPDM is one of the most popular options on the market. This rubber material is incredibly durable and designed to withstand harsh weather conditions, making it a great choice for flat roofs. In addition to its durability, EPDM is a cost-effective solution that can last up to 30 years.


A metal roof can provide a lifetime of use with proper maintenance and repairs. Its longevity will depend on factors such as the type of metal, its finish, and the roof’s incline. As long as proper upkeep is performed and necessary replacements are done when needed, a metal roof can last an eternity.

Thermoplastic Olefin (TPO)

TPO roofing is an excellent choice for businesses that want a long-lasting, durable roofing solution. It is a single-ply membrane composed of a combination of polyester and reinforced polypropylene materials, making it highly resistant to punctures, tears, and extreme weather. 

TPO is also incredibly lightweight, so it can be installed quickly and efficiently. With regular maintenance and inspections, it can last up to 30 years, making it a great investment for any business.

Preserving Roofing Life Span

The lifespan of a commercial roof is heavily dependent upon many aspects. Taking proper care of it and making necessary repairs is of utmost importance, but the materials used, the design of the roof, and the quality of installation are also major factors. 

Opting for top-notch materials and a well-structured design can extend the life of the roof. Additionally, familiarity with the components of different roofing materials can benefit when making decisions about the roofing system.

The design of the roof is also a significant factor in determining its lifespan. A well-structured roof designed with the environment and climate in mind will be more durable and last longer. It’s essential to consult with an experienced roofing contractor to ensure that the design is optimal for the climate and environment.

Lastly, the quality of installation is also an important factor in determining the lifespan of a commercial roof. Poorly installed roofs are more likely to suffer from leaks and other problems that can shorten the roof’s lifespan. Always make sure to hire experienced contractors who are familiar with the components of the roofing system.
