Right on Target

Stock Roofing installs a vegetative roof system on Minneapolis' Target Center

In the heart of Minneapolis' thriving Warehouse District, amidst a plethora of restaurants, bars, theaters, hotels and shopping venues, is the Target Center, one of the Midwest's largest entertainment facilities. Owned by the city and sponsored by Target Corp., which is based in Minneapolis, the arena encompasses 831,533 square feet and can accommodate up to 20,500 people. Since opening Oct. 13, 1990, the center has hosted about 4,000 events and ­­­­­­welcomed about 25 million people.

The center, originally constructed for and owned by the Minnesota Timberwolves, was purchased by the city in 1995. When it came time to replace the center's 20-year-old roof system, the city undertook a project to install a vegetative roof system on the 2 1/2-acre main low-slope roof, as well as reroof 29 smaller roofs on five lower levels of the building.

The project was put out for public bid in September 2008, and Stock Roofing Co. LLC, Fridley, Minn., a Tecta America company, was awarded the project Jan. 29, 2009.

The installation and ongoing maintenance of the 113,000-square-foot vegetative roof system—the fifth largest extensive vegetative roof system in the U.S. at the time of its installation—is the project's final stage.
