A typical roof can be riddled with tricky transitions that require careful thought towards detailing. Transitions not only need to consider the integration of different materials, but also the continuity of the control layers—water, air, thermal and vapor. There are a few tricky transition areas that can be overlooked or improperly detailed in the design process, and are sometimes left for the contractor to “figure out.” Some of these overlooked and underappreciated details include: steep-slope to low-slope integration, rising walls, clerestories, parapets and drainage. This webinar will explore some of the considerations to properly detail these tricky transitions, including commentary on installation coordination and execution.
