Two new members have joined the Metal Roofing Alliance: CertainTeed, a building materials manufacturer, and Decra Roofing Systems, a manufacturer of stone-coated metal roofing.

“The addition of CertainTeed and Decra is an important development for the MRA, as it adds two major manufacturers of building and roofing materials to our organization,” said Bill Hippard, executive director of the Metal Roofing Alliance. “Our goal is to reach 20 percent market share by 2020, and manufacturers such as CertainTeed and Decra are going to help us reach that milestone. All segments of metal-roofing supply chain can benefit from additional growth, from raw materials suppliers and coil coaters to manufacturers and contractors.”
