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.
