IBC & ASCE 7-16 is Changing - WSRCA's Bottom Line

Posted By WSRCA, Tuesday, December 18, 2018

 

It has come to the attention of WSRCA’s Low-Slope and Industry Issues Committees that the 2018 International Building Code (IBC) is continuing to be adopted by more jurisdictions in the Western U.S. Please be aware that there are changes in the 2018 edition of IBC’s Chapter 15 for Roofing and its companion Chapter 16, which relates to wind-uplift resistance. These changes adopt, and requires use of the relatively new 2016 edition of the American Society of Civil Engineers “ Minimum Design Loads And Associated Criteria for Buildings and Other Structures” – (ASCE 7- 16 Standard) to determine wind-uplift design pressures for roof system attachment/securement. These changes are relatively complex, and Contractors may want to contact the Roofing Manufacturer for direction regarding roofing attachment (e.g., mechanical fastening schedules) or securement (e.g., low-rise foam adhesive bead size and spacing schedules). Contractors may also desire to carefully consider the potential affects (e.g., increase) with some materials, and labor for any additional mechanical attachment, foam adhesive, or other related roof securement needed.
 

Executive Summary:


Western States Roofing Contractors Association (WSRCA) believes that it is important to alert you to the value of being aware of changes to the code, as not knowing could have a dramatic effect on the success of any roofing or reroofing construction business.
