Hear from our leaders in the Building and Roofing science.

Sign up for our building science newsletter.
Companies, organizations, and firms working in the building, construction, and design space have a unique opportunity and responsibility. Collectively, we are contributing to nearly 40% of energy-related carbon emissions worldwide. While the goals, commitments, pledges, and promises around these challenges are a step in the right direction, no one entity alone will make major improvements to this daunting issue.
With any roofing project, there are a number of factors to consider when choosing the right design: sustainability profile, potential risks, overall performance, and more. Our Building and Roofing Science (BRS) team specializes in working with industry professionals to help them enhance their roof designs across all of these areas. Leveraging their building enclosure expertise, our BRS team serves as thought leaders and collaborators, helping design professionals deliver better solutions for their customers.
Much of the damage that happens to roofs during high-wind events starts at the perimeters and corners. This means that the edge metal system at the roof-to-wall interface is critical to a roof's success during wind events. The roofing industry is well aware of this phenomena; investigating roof damage after high winds has been taking place for decades. This issue is so important to the roofing industry that an organization was formed to investigate, learn, and provide insights and recommendations to the industry so we can improve the edge metal installed at roof-to-wall interfaces. This organization, RICOWI–the Roofing Industry Committee on Weather Issues–was formed in 1990 specifically to "identify and address important technical issues related to the cause of wind damage." Much has been learned from these investigations and full credit goes to RICOWI for spearheading this effort! This photo from RICOWI's investigation of Hurricane Micheal shows the importance of the roof-to-wall interface.
During summer months, cities get hotter than surrounding areas. Trees and vegetation found in suburban and rural areas help reduce temperatures on sunny days. In contrast, tightly packed and tall city buildings tend to trap heat. To make matters worse, city buildings retain that heat and release it during the night due to their thermal mass.
