COMMERCE CITY, Colo. — After 18 years of operating separate companies under one roof, D&D Roofing, Inc. and D&D Monarch Sheet Metal, Inc. are consolidating their services and merging with Flynn Companies of Toronto. The merger is effective Jan. 4, 2016, and the combined company will be known as Flynn Southwest.

The consolidation will help allow the previously independent companies to achieve their combined goal to become a true "building-envelope" company with capabilities to install glass on any existing or new structure up to 50 stories tall, according to a news release. Other new offerings will include water proofing, green roofing and solar.

Rob McReynolds, D&D Roofing's president and senior project manager, said he expects immediate growth in the sheet metal division through the expansion of wall panel services. The company will also implement a system for quicker billing and roof inspections to enhance the customer experience. Other changes include both McReynolds and colleague Ty Mattern having a boss.

"I haven't had a boss in 18 years," McReynolds said in a news release. "Putting my title 'President' and my ego away was easy once I realized what Flynn represents."

D&D was 32nd on Roofing Contractor's 2015 Top 100 list, and Flynn was 15th. 

"For us to expand and have a great outlook for our current employees and customers we needed a change," McReynolds explained. "With Flynn we feel we have found a similar company with similar goals, professionalism, and with safety being the number one priority."

Flynn Companies has six other locations in the United State and 19 branches in Canada. 

"It is extremely exciting to be able to compete at a level that was unimaginable without the resources that Flynn brings to the table," Mattern said.
