Green attributes affect roofing material selection

Interviews performed by Ducker Worldwide LLC, a Troy, Mich.-based market research and consulting company, indicate sustainability and green design are the most influential trends affecting roofing material selection.

Conducted among various roofing industry segments, including suppliers, manufacturers, contractors, architects/specifiers, general contractors, builders, building owners/facility managers and consumers, the interviews also indicate energy efficiency affects roofing material selection more than any other environmental trend. Additionally, the interviews indicate the difference in design and availability of alternative materials, such as higher R-value insulation, cool roofing materials, vegetative roof systems and integrated solar roof systems, have the most significant effect on roofing material selection.

The interviews show the use of green roof systems has become increasingly important since 2002, particularly for roofing contractors and end users. In 2008, it was estimated that less than 10 percent of roofing projects were constructed using green materials and/or systems. By 2013, this number is expected to triple though current economic conditions could slow such growth. More than 75 percent of interview respondents claim to have experienced growth in green roofing practices during the past five years, and all respondents believe growth will continue through the next five years.
