How Long Does A Commercial Roof Last?

How Long Does A Commercial Roof Last?

A commercial roof typically lasts between 20 to 30 years. There will be many variables that determine the length of time it lasts. Such as the material and the wear and tear it takes. Our expert commercial roofing contractors explain how long your roof should last – and what you can do to increase its lifespan.

Types Of Roof Material

Let’s start with the material used and its life expectancy. There are several popular materials used by commercial roofing contractors in Ohio:
● EPDM: Usually installs on flat roofs like malls and warehouses. It’s a rubber material that doesn’t last as long as others. Its average lifespan is anywhere between 15 to 40 years.
● TPO: Mostly used on flat roofs, lasting anywhere from 20 to 30 years. They are highly energy efficient and have a high resistance to damage.
● Metal: It’s highly resistant and lasts longer than other types. They’re used for sloped roofs and last between 30 to 70 years.
● Asphalt: Low-slope asphalt roofs typically last 15 to 20 years, whereas high-slope roofs last between 20 to 30 years.

What Affects My Roof’s Lifespan?

There are many reasons why you may need commercial roofing in Cincinnati, Ohio. Here are three common causes of damage that reduce your roof’s lifespan.

1. Severe Weather

You can’t change or stop the weather, but you can take a few steps to help prevent serious damage. If you have trees around your building, trim them to where if they break off, they won’t land on the roof. Damage due to weather can start small and eventually become a major issue. They can begin as small leaks that, if not detected, will soon turn into a structural issue or create mold. An untreated leak is an expensive leak. You may have to repair the building’s ceiling, walls, or structure. It’s best to have commercial roofing contractors inspect your roof at least once a year to prevent any serious damage.

2. No Maintenance

A roof that lacks maintenance will most likely fail at or before 15 years. This may seem long enough, but they can last up to 30-40 years with proper care. Repairing or patching areas is thousands of dollars cheaper than a replacement. It’s best to get regular maintenance to keep your commercial building’s roof structure in good condition. A commercial roofing company will inspect the inseams, flashing, scuttles, ladders, and more.

3. Aging

Even the best roofing system will eventually fail due to aging. Some factors will make the roof deteriorate and age faster. Excessive heat, improper roof ventilation, mold growth, and poor roof design and installation are common issues when roofs get old. The materials used will also make a major difference in how long your roof lasts. There will come a time when repairs won’t be enough, and you’ll need commercial roofing in Cincinnati, Ohio.


There are many reasons a roof may fail.
