Roofing industry studies have the potential to improve roof technology and spur roofing innovation. The Roofing Alliance, the Foundation of the National Roofing Contractors Association (NRCA), funds these types of studies to help drive the roofing industry toward a bright future. In part one of this two-part series, we provided a brief overview of roofing industry studies funded by the Roofing Alliance including:
Through these exhaustive studies, researchers can develop new roof technology to improve productivity, safety, and employee satisfaction in the roofing industry. In this article, we will discuss more of the studies funded by the Roofing Alliance, a membership-based organization and endowment fund.
The Roofing Alliance contributed to a roof reflectivity study in 2005 in which NRCA’s Technical Operations Committee worked in conjunction with representatives from the Chicago Roofing Contractors Association to measure solar reflectivity on various roofing systems throughout Chicago’s sprawling metropolitan area. Data was collected from 50 roofs over a five-year period.
This study was conducted in 2009 to survey the performance of 600 Florida-subsidized rooftop solar installations. Arguably the most important roofing innovation in the last 20 years, photovoltaic systems have helped improve sustainability in the roofing industry significantly. This study was inspired by the white paper Successful Rooftop Photovoltaic: How to Achieve a High-Quality, Well-Maintained, Compatible Rooftop PV System.
The Roofing Alliance contributed funding in 2009 and 2012 to explore the results of the Asphalt Roofing Environmental Council (AREC) Dermal Cancer Assay (skin painting study) of Type IV BUR Asphalt Fumes. In 2011, the International Agency for Research on Cancer (IARC) reported that emissions from oxidized asphalt were “probable” human carcinogens. The Roofing Alliance contributed additional funding to help expand this research.
Additional funding was awarded to this study which helped improve compliance with International Energy Conservation Code, 2012 Edition (IECC 2012). The goal of this study was to review data from the NRCA/Chicago Roofing Contractors Association and develop an appropriate testing method for the evaluation of mechanically fastened roof assembly types. Another important consideration of this study was the results of air barrier placement on the accumulation of moisture within roof assemblies.
More recently, the Roofing Alliance provided funding for the following programs and studies currently in progress:
