Close-up

Asphalt is one of the oldest materials used in the roofing industry. Although asphalt can be an excellent waterproofing material, it tends to crack as a result of freeze-thaw cycles. To increase the thermal window and improve strength and performance, various modifiers have been added to asphalt.

At The Garland Co., Cleveland, researchers have been working on OptiMax,™ a roof membrane that combines polyurethane and asphalt, producing an active modification process that causes the polyurethane to chemically react with the asphaltene to reduce the effects of exterior exposure. Surfacing minerals are attracted to polyurethane and adhere longer, reducing the aging process.

  • Metal ahead

    Metal roofing has gained popularity in the commercial marketplace, and the trend appears likely to continue. Since 2009, metal has achieved an annual growth rate in share percentage of about 4 percent, according to a 2015 study published by FMI Corp., Raleigh, N.C. As a result of its energy-efficiency characteristics, longevity and design flexibility, metal roof systems are being selected by more customers.

  • A diamond on the Brazos River

    Located in Waco, Texas, Baylor University was chartered in 1845 and is the world's oldest Baptist university. Baylor University strives to prepare its students for worldwide leadership and service, but the campus community also enjoys rallying around its sports teams. When Baylor University built a new football stadium, administrators selected local roofing contractor Johnson Roofing Inc. to install a TPO membrane roof system on McLane Stadium.

  • The next labor shift

    The first major labor shift within the roofing industry occurred during the past 25 years when a primarily Anglo-Saxon and African-American workforce shifted to a significant Latino workforce. The roofing industry soon may experience a second labor shift as more second-generation Latinos join the workforce. Understanding generational differences between first- and second-generation Latinos will be crucial for the successful management of these workers.
