Directory of Roof Assemblies (DORA) 

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.

Why use?

  • Steel, concrete, wood, cementitious fiber, gypsum and panelized concrete roof decks
  • Latest advancements in intuitive searching techniques to find assemblies meeting your specific design criteria
  • Robust project management and collaboration tools
  • Saved searches and optional email notifications for new assemblies meeting your specifications
  • No erroneous assemblies or products
  • Mobile-friendly
  • Free to public

Wind Design Calculator

This Wind Design Calculator is used to calculate the roof edge design pressure.

All versions of International Building Code since 2003 have required per Section 1504.5 that metal edge systems, except gutters, be tested per ANSI/SPRI ES-1 or ANSI/SPRI/FM 4435/ES-1 to resist wind loads in accordance with Chapter 16. The 2021 version of IBC will also require some gutters to be tested per ANSI/SPRI GT-1.

This calculator is based on ASCE 7 as prescribed by IBC Chapter 16, and can be used to calculate the design loads that edge metal systems must be tested to resist.
