DENVER — Two Johns Manville (JM) energy-generating and energy-saving asphalt roofing projects were awarded top honors in the 2013 Asphalt Roofing Manufacturers Association’s (ARMA) third annual Quality Asphalt Roofing Case Study (QARC) competition.

American Roofing & Metal Co. Inc. of Louisville, Ky., received the Bronze award for its American Life & Accident Insurance Co. project: a sustainable, two-ply JM modified bitumen system topped with a vegetative green roof.

Ultimately, this JM-modified bitumen system was chosen due to its durability, watertight properties, and the ability to include a leak detection feature over the JM cover board. The result: the largest green roof in Kentucky, estimated to cut the building’s heating and cooling costs by a minimum of 20 percent.

McEnany Roofing and Contracting Inc. of Tampa, Fla., received Honorable Mention for its Saint Petersburg College of Natural Science and Math Building project: a roof integrating a hybrid JM SBS/BUR system with a JM thin-film photovoltaic system. The project successfully converted the roof of the LEED-Gold Certified building into an energy-generating asset for the campus.

“The projects highlighted in the QARC case study competition reinforce the Johns Manville commitment to making buildings more energy-efficient,” said Katherine Domenico, JM product manager and delegate to ARMA. “The benefits of energy efficiency within commercial structures are immeasurable, and we pledge to continue our focus on offering innovative, energy-efficient solutions to our customers.”

The national QARC awards program seeks to recognize innovative asphaltic roofing solutions in North America. It is the only national awards program in the country that honors outstanding new commercial and residential asphaltic roofing projects.
