Why Us
Superior Service, Reliable Repairs, Employee Owned
MGC Roofing & Construction, Inc. is 100% Employee Owned. We pride ourselves on quality. Nearly 20 years ago, our President Marvin Campbell, decided to take a leap of faith and enter the market with his wife. Marvin has successfully cornered the market and made a strong and reputable name for the MGC banner. Marvin wanted to share that passion and extend ownership to all of his employees. He sold MGC to its employees by becoming an ESOP in 2018.
MGC has two primary divisions, the Department of Defense nationwide as well as a service department located in central and south Florida. We have been in business for 18 years and have over 150 collective years of roofing experience.
We specialize in Shingle, Slate, TPO, PVC, EPDM, SSMR, BUR, and Modified Bitumen. However, we install, repair, and coat many other roof systems. It would be our pleasure to assist you and add you to our long list of long-term satisfied customers.
