2025 Convention Session: Bridging Enclosure Gaps: Creating Continuity Between Roofing and Adjacent Enclosure Systems (Garbis, Wowk, Narcis)

Course Overview
This session was originally presented at the 2025 IIBEC International Convention & Trade Show in Orlando, Florida.  This course includes the following components:

• recording of the live session
• a summative assessment consisting of 10 multiple-choice questions
• two surveys required to claim continuing education credit

Description

Roofing systems play a crucial role in achieving seamless integration between horizontal and vertical enclosure systems. As building enclosure performance requirements continue to rise, roofing systems of a building’s enclosure become more rigorous, and enclosure systems become higher performing. To meet this demand, roofing systems are often called upon to ensure continuity in (thermal, airtightness, and waterproofing aspects) between horizontal and vertical enclosure systems. Often, the detailing, material compatibility, and durability at roofing transitions can ensure the overall effectiveness of the building’s enclosure performance. This presentation looks to explore some of the challenges often overlooked during the design of roofing transitions and emphasizes the importance of discussing detailing at edge conditions. By addressing material compatibility and durability and ensuring effective continuity, roofing systems contribute significantly to the overall effectiveness of a building's enclosure performance.
