Directory of Roof Assemblies

DORA is a comprehensive database service of roof systems tested in accordance with standards referenced in Chapter 15 of the International Building Code (IBC).
This service is free to public and lists wind uplift load capacity on single ply and modified bitumen roof systems. Assemblies may be easily searched, viewed, saved, and printed.

How Does DORA Work?

DORA works through the voluntary participation of industry companies. All roof assemblies are submitted by participating companies and are accompanied by supporting documentation in the form of test reports and qualified evaluations.

DORA accepts supporting documentation from any qualified accredited laboratory or certification body. All supporting documentation is independently validated before entering DORA. All roof assembly submissions are reviewed and independently verified by the Program Administrator before being published to the website.

DORA is sponsored by SPRI and administered by Intertek
