Whether you own a corner cafe or an industrial plant, maintaining your commercial building is crucial to the success of your business—including taking care of the roof. As with your home, commercial roofing systems require periodic repairs and will need to be replaced eventually as well. The following information offers guidance on how to tell it’s time for a replacement and what you need to know about the installation process. 

Commercial Roofing 101 

How do I know I need a new roof? 

The life span depends on a variety of factors, including material, climate, and maintenance. However, as a general rule, commercial roofs tend to last 25 to 30 years. You should have a professional assess the roof every 15 years to determine if repairs are needed. If you need to have it serviced often, it may be more cost-effective to get it replaced. Mold, cracks, and water stains may also indicate the need for a replacement, especially if the issue is widespread or accompanied by other problems. These issues can make a roofing system unstable and unsafe. 

What material should I use? 

There are many types of commercial materials available, and your choice will depend on your aesthetics, budget, and climate. Ethylene propylene diene terpolymer (EPDT), is a durable synthetic rubber option commonly used on low-slope buildings. Polyvinyl chloride (PVC) is another popular option for commercial roofing as it is durable, flexible, and UV stable. A third material used in many commercial roofs throughout the U.S. is thermoplastic polyolefin (TPO), which is similar to PVC. Consider energy efficiency as well. Spending more on an energy-efficient roofing system could save you money long-term by reducing your heating and cooling costs. 

Can I install a new one over the old one? 

It is usually best not to install a new roof over an old one. You can’t be sure that moisture isn’t trapped under the old roof without removing it. If there is moisture under the old roof, it may compromise the efficiency of your new roofing system and cause issues like leaks and water damage. Replacing it may take a bit longer but will ensure there are no hidden problems. 

How long will it take?

Commercial installations take longer than residential ones to install, though the total time will depend on the material used and the size of your building. Weather can also factor into the installation timeline. Typically, commercial installations take one to four weeks to complete.
