RELEVANT CODES AND STANDARDS
Prior to 1990, the three model building codes (BOCA National Building Code, Standard Building Code, and the Uniform Building Code) contained few provisions pertaining to roof systems. Additional provisions were added to these codes during the 1990s. The International Building Code (IBC) has many provisions related to roof systems, including reroofing projects. Code requirements pertaining to roof systems originally primarily addressed life-safety issues, such as fire resistance. However, the IBC also includes provisions pertaining to general serviceability, such as minimum roof slope.
Building code requirements can be quite different from those of the membrane manufacturer or FM Global. It is therefore important for the roof system designer to carefully consider the code requirements. The designer should determine if a building code has been adopted for the locale where the roof will be installed and, if so, what edition of the code is to be used. If the building occurs in an area that has not adopted a building code, it is prudent for the designer to voluntarily comply with the roofing-related provisions of a current edition of a model code such as the IBC.
The building code may have specific requirements regarding documentation to be provided to the building department. For example, the IBC has construction document requirements in sections 107 and 1603 (2012 edition).
Most building departments possess little expertise related to roof systems. Designers should therefore not rely upon the building department to discover non-code compliance during their plan review. Also, most building department’s inspectors do not inspect the roof system. Those departments that do inspect the roof likely possess insufficient knowledge of all of the systems that they could encounter.
NRCA publishes a number of documents regarding building and energy code requirements for roof assemblies. They include:
- Guidelines for Complying With Energy Code Requirements for Roof Assemblies: International Energy Conservation Code, 2009 and 2012 Editions. This document also covers the relevant roofing-related provisions of ASHRAE 90.1—۲۰۰۷ and ASHRAE 90.1—۲۰۱۰٫
- Guidelines for Complying With Building Code Requirements for Roof Assemblies: International Building Code, 2009 Edition.
- Guidelines for Complying With Building Code Requirements for Roof Assemblies: International Building Code, 2012 Edition
- NRCA Guidelines for Roof Systems With Rooftop Photovoltaic Components
NRCA also maintains a list of currently-adopted state energy codes on their website (nrca.net).
