Simplifying the Complicated Process of Wind Design for Roof Systems

In 2022, GAF launched a first-of-its-kind initiative in Pacoima, one of the hottest neighborhoods in Los Angeles, to explore community-wide solutions to combat urban heat. The GAF Cool Community Project is addressing the complex issue of extreme heat through a research-driven approach: Take a hot, sun-exposed community with an abundance of heat-retaining surfaces. Then, apply solar-reflective coatings to its streets and public hardscapes. With resources and support from GAF and non-profit partners, more than 700,000 square feet worth of streets, parking lots, and other hardscapes were coated with StreetBond DuraShield with Invisible ShadeTM technology over a contiguous 10-block area. The formerly dark streets were transformed to a cool gray-blue, and colorful coatings brighten the basketball courts and other public gathering spaces.

Longtime fixtures of playgrounds and recreational areas, sports courts have a lot to offer. In addition to providing opportunities for children and adults to participate in physical activities, they can strengthen communities. There are also other benefits when courts are designed to reduce surface temperatures and protect substrate materials.

What is going on here? No, this roof does not have measles, it has a problem with thermal bridging through the roof fasteners holding its components in place, and this problem is not one to be ignored.

GAF is committed to building more resilient communities in the areas where we live and work. Working with our network of manufacturing communities, we can leverage our expertise, resources, and products to help protect the places we call home. Our local teams lend their time and talents to address the unique needs of each community, as we help support the fundamental needs of shelter, families and workforces.

Cold storage facilities face unique challenges when it comes to maintaining optimal interior temperature levels. Development of cold storage roofing system design documents that both maintain interior temperatures and create an airtight roof system are important to have a high-performing cold storage roof. Uncontrolled airflow into the roofing assembly can lead to condensation within the roof and the presence of icicles or ice balls at the underside of the roof deck. Condensation and ice in the roofing assembly adds weight to the roof assembly, and wet insulation has significantly reduced R-value. A reduction in R-value means that it is more difficult for the insulation to retain interior temperatures, and cooling equipment has to work harder to maintain the interior temperature set points.

Cold storage facilities face unique challenges when it comes to maintaining optimal interior temperatures. One crucial aspect in ensuring efficient temperature control is creating an airtight roof system which can help prevent cooled interior air from escaping, warmer exterior air from entering, reduce thermal loss and condensation potential, all while promoting energy efficiency and prolonging the life of the roof system and building.
