It is challenging to specify the right materials and assemblies for a commercial roof system to satisfy a building’s specific performance and safety requirements. Even with design considerations in place, existing resources for finding applicable roof assemblies are limited in scope and can feel disconnected. These fundamental challenges gave way to a large initiative from SPRI (Single Ply Roofing Industry) to create a solution to empower manufactures, consultants, architects, building owners, and code officials with a better way.
The Directory of Roof Assemblies (DORA) is a web application database of low slope roof systems tested in accordance with standards referenced in Chapter 15 of the IBC. This service lists wind uplift load capacity of single ply roof system. Here is the web site for more information: www.dora-directory.com.
