How Long Does A Commercial Roof Last?

Commercial Roofing company

A commercial roof can last anywhere from 10 to 40 years, and there are certain factors that will affect its longevity, including the following:


There is no getting around this aspect, and harsh climate conditions will wear down a roof over time. This can result in degradations to your roofing system, and the integrity of a commercial roof will be affected by weather, especially if your building is in a climate where there is freezing ice. This can wear down your roof fast, and once the water thaws, this moisture will seep into the gaps and will refreeze, and this expansion will result in small cracks and leaks. Hot temperatures can also affect your roof's longevity because it can harm the sealant materials, which can wreak havoc on a commercial roof. The good news is that preventative maintenance can help immediate repairs, so do not delay this step and make sure you regularly inspect your commercial roof.

Roof Type

The type of roof you have will influence how long a commercial roof will remain functional, and you will be able to choose a flat roof, a low-sloped roof or a pitched roof. Each of these options has its advantages and disadvantages, and knowing this information will help you select the best roof type for your building. Flat roofs are faster to install, but inadequate drainage is a problem you will run into, and standing water on your roof will weaken its structure and result in rapid roof degradation and leaks inside your building. Low sloped roofs will promote water runoff, so fewer repairs will be required, but when heavy snow doesn't melt, a lot of weight will be added to your low sloped roof.

Roofing Materials

A PVC roofing system, a TPO roof system, a metal roof system, an EPDM roof system and an asphalt roofing system are all examples of common roofing materials, and each one will play a role in the longevity of a commercial roof. PVC roofs are known to last for 20 years or more, while TPO roofing systems can last anywhere from 22 to 30 years. Metal roofs can last 30 to 45 years, asphalt roofing systems can last 20 to 40 years, and an EPDM roof system can last 22 to 35 years. Choosing the right material is a must because this can significantly increase your roof’s lifespan.
