Chapter 15 of the IBC and the Oregon Specialty Structural Code addresses the code requirements for the design and construction of roof assemblies. Ranging from slope requirements to requirements regarding specific roofing types, including thermoset, thermoplastic and SBS roofing materials, this section of the code is not frequently discussed or referenced during the course of project design and delivery. Mr. Kouba will address these requirements as well as looking at both the requirements and methods for compliance for meeting wind loads and edge securement. Mr. Kouba will clarify what Class A, B and C roofs are and what the criteria are for UL or FM listed roof assemblies. In addition, specific aspects of the code that address the requirements regarding vegetated roof gardens will be discussed.
