How Long Does Your Type of Commercial Building Roof Typically Last?

While a properly installed commercial roof can last an average of 20 to 40 years, there is no direct answer to the question of how long a commercial building roof will last. The reason for this is because there are many factors that affect the lifespan and there are also things that a building owner can do to extend the life of the roof.

Factors that affect the lifespan of a commercial roof Weather

Regardless of how strong a roofing system is, it is no match for Mother Nature. The ice, snow, rain and strong winds will eventually erode the roofing materials. Exposure to the sun will also have a negative impact on the roof; this is more so if the roofing material is darker.


How a commercial roof was installed will also affect its lifespan. Most roofs fail prematurely because of poor installation. This is because minor flaws in the installation will shorten the life of a roof drastically. It is very important that you leave the installation work only to commercial roofing experts.


Poor ventilation will damage your roof because when it is hot the heated air will be trapped inside and cook the roofing materials. Asphalt is more prone to this problem. Poor ventilation in cold weather, on the other hand, will lead to ice buildup and moisture may be trapped inside causing rot or mold.


The pitch or slope of your roof will determine how well it gets rid of water. Low-sloped roofs have a shorter lifespan because water is not shed quickly. This causes water buildup. Pooled water will cause leaks and eventually damage the roofing structure.


Regular maintenance helps spot problems before they get worse. If you don’t inspect your roof after harsh weather, it will be vulnerable. Regular maintenance will help take care of small issues that could get bigger.


Last but not least, you should remember that the materials used in a commercial roof will determine how long the roof lasts. Roofing materials have varying lifespans: asphalt lasts 15 to 20 years, metal 30 to 40 years, Thermoplastic Olefin (TPO) 20 to 30 years and Ethylene propylene diene monomer (EPDM) 25 to 30 years. Choose the materials carefully.

How to make your commercial roof last longer

Just because your commercial roof has an average lifespan of 30 years it does not mean it can’t last long. Here are some crucial things you can do to make your roof last the longest.

Perform regular inspections

Lack of care is the root cause of early failure. Your roof needs to be inspected by a professional at least once a year.

Make immediate repairs

Never take too long to repair damages. Small issues can escalate fast.

Apply the right coating

Applying the right coating is the best way to make your roof last longer. The coating helps restore the roofing material as well as offer protection from UV rays.

Only hire commercial roofing experts

Having the installation, inspection and repairs only done by commercial roofing experts will ensure the roof lasts as long as possible. Don’t handle the repairs on your own or work with inexperienced roofing contractors.
