Keystone Roofing Inc., Oceanside, Calif., has won a Gold Circle Award every year during the past five years. Besides its winning project for 2010—a private estate in San Diego—the company also has won Gold Circle Awards for:

• Semper Fit Field House: In 2006, Keystone Roofing won a Gold Circle Award in the Innovative Solutions—New Construction category for Semper Fit Field House, Camp Pendleton, Calif. The company fabricated and installed a standing-seam metal roof system on the 65,000-square-foot facility, which housed two gymnasiums, four racquetball courts and a wellness room, among other features. The company overcame challenges involving the buildings' shapes, including a barrel roof and curved radius wings. To learn more about the project, click here.
  
  
• Eilenberg-Tarter residence: Keystone Roofing received a 2007 Gold Circle Award in the Innovative Solutions—Reroofing category for the Eilenberg-Tarter residence, Cardiff by the Sea, Calif. The company installed zinc-coated copper with standing-seam panels, roll-forming the panels on-site and taking extra caution when maneuvering the panels, some of which were 65 feet long. The house's roof had eight equilateral triangular roof segments in two wings, and each of the four segments had a different roof slope. To learn more about the project, click here.
  
  
• Lagazo residence: In 2008, Keystone Roofing won a Gold Circle Award in the Service to the Community category for the Lagazo residence, San Diego. The company installed a wood shingle roof system on the home, a project that had been abandoned by two previous roofing contractors. The original roofing contractor had removed the home's original roof system and improperly installed 5/8-inch-thick oriented strand board, securing the board with only about six nails per sheet. Additionally, improper installation of felt paper allowed water into the home. Under time constraints, Keystone Roofing finished the project correctly—free of charge.

• Private estate: Keystone Roofing received a 2009 Gold Circle Award in the Innovative Solutions—New Construction category for a private estate in Southern California. The company installed a clay tile roof system on the 45,000-square-foot estate, which included six wings and a 60-car garage for the homeowner's Ferrari collection. A unique roof system was required to complement the building's complex geometry, and clay tiles were molded into pan shapes specifically for the project; special molds were made, used and broken so no one could replicate the shapes.
