What is the Expected Lifespan of a Commercial Roof?

The roof of your business is an essential part of the building yet is one of the most overlooked. When it is doing its job without any problems, it is out of sight, out of mind. However, when issues arise, you can’t help but notice it and nothing else. 

Being aware of how long you can expect your commercial roof to last will allow you to prepare for potential repairs or a replacement instead of having it come at you out of the blue. Repairing or replacing a roof can be expensive and can become catastrophic if you do not save or plan properly. 

How Long Does a Commercial Roof Last?

There are many factors that go into how long a commercial roof can last, such as when it was installed, how it has been maintained, the materials used, and the type of weather where you are located. 

For a general answer, a commercial roof is expected to last anywhere from 10 to 40 years. The following are the most common types of materials used in the construction of a commercial roof and their expected lifespan. 

  • Ethylene propylene diene terpolymer, also known as EPDM, and can have a lifespan of 22 to 35 years.
  • Thermoplastic polyolefin, also known as TPO, with a general life expectancy of 22 to 30 years.
  • Metal roofs have a general life span of 30 to 45 years.
  • Polyvinyl chloride, also known as PVC, with a life expectancy of 20 to 30 years.
  • Asphalt roofs have a life expectancy of 20 to 40 years.

Materials are not the only aspect that play into the life expectancy of a commercial roof. 

Common Factors That Determine the Lifespan of a Commercial Roof

The following are considerations you should think about when installing your commercial roof, as they can each have a part in the lifespan of the roof. These are based on expected lifespans; therefore, keep in mind that you could have all these factors and your roof could still last for 40 years. 

Slope – When the roof is flat, it is more likely that water will gather on the surface. When water does not travel down the roof and onto the ground, it will locate the lowest point and remain there until it evaporates. These low spots are usually where damage begins, and leaking is often the first sign of damage. 

Installation – The installation of the roof is the most important part of the process. Any mishaps that occur during the installation process can eventually shorten the lifespan of a roof. Choosing a reputable, well-qualified, experienced contractor is vital when you need a new roof installed. Do not search for the cheapest option. It will be well worth it to pay a little extra to make sure that you get the kind of work done that is needed. 

Ventilation – The attic area that is right under the roof itself needs the correct ventilation because it helps stop the build-up of moisture and heat. Correct ventilation is important during the summer when the warmer temperatures in the attic area, as well as on the roof, will basically cook the roofing materials. Mold and rot can be a result of built-up moisture, which can cause many other problems for your building. 

Weather – Mother Nature is something you cannot control. Depending on the area you live in, your building could be vulnerable to higher winds, hail, heavy rainfall, or heavy snows. These elements can wear on a roof over time and decrease the lifespan. 

Maintenance – Maintenance on anything can seem like a big headache but having regular maintenance and inspections on your roof can stop small problems from turning into larger ones. It can be easy to neglect your roof, but it is essential that you do not ignore any problems, no matter what. Any problem can lead to bigger issues that could make your commercial building unsafe.
