LATEST FROM GAF ROOFVIEWS
Since its inception a roof's primary purpose has been to shelter its inhabitants from the elements, but now the underutilized potential of roof surfaces is being realized. For roofs with large surface areas, the potential for large overburden installations, such as solar, vegetative roofing, or amenity decks can be exceptional. Even smaller roofs can have overburden that make a significant impact on the sustainability goals of a building including: increased energy efficiency, stormwater retention, energy generation, biohabitat restoration, food production, reduced urban heat island effect, and outdoor space.
Roof systems require a number of performance properties, in addition to keeping water out of a building. Those properties include fire resistance, wind resistance, impact resistance, and R-value of the installed system, to name a few.
Specifying the right materials and assemblies for a low-slope roof system to satisfy a building's specific performance and safety requirements can be challenging. Even with design considerations in place, existing resources for finding applicable roof assemblies are limited in scope, functionality, and can feel disconnected. This is where the Directory of Roof Assemblies (DORA®) can help!
Keeping water out of a building is undoubtedly the primary function of a roof system. But one could argue that ensuring a building's roof stays in place during high-wind events is equally important. Let's face it, without a roof, it's hard to keep water out! This blog takes a look at one of the subsets of wind design of roof systems: Wall Zones 4 and 5 and their relationship with roof perimeters.
