FAQs

Can I use residential roofing materials on my commercial roof?

Depending on the construction, some residential products are incorporated into commercial roofing, like slate or metal on a pent roof. However, you should usually use commercial roofing materials on your commercial roof.

Is there a difference between residential and commercial roofing materials?

While residential and commercial roofs may seem similar, there is a difference in the materials you use when installing a commercial roof. For more contrasts between residential and commercial roofing, check out our blog explaining both in depth.

Does a commercial roof need inspections?

Your commercial roof should be inspected and maintained by a roofing contractor twice a year. Regular maintenance can identify and address issues, prevent future problems, and save money on repairs. It can also improve roof performance and extend its lifespan.

Can I DIY my new commercial roof?

No, it’s not recommended to do any commercial roofing yourself. Most roofing manufacturers and professional companies offer warranties that require professional installation. If you do the work yourself, you won’t be protected if there are defects or premature failure.

DIY projects can also be costly, and you might end up buying expensive materials and tools that don’t work, or damage your roof even more. So it’s best to leave this to a professional contractor. And if you don’t have a contractor, we can connect you with one from our network.

How long does a commercial roof last?

With proper maintenance, a commercial roof can last between 15 and 50 years. Factors like local climate, roofing materials, installation quality, and ongoing maintenance play a significant role in its lifespan.
