ABOUT THE EVENT
Drainage is a critical aspect of low-slope roof design involving not only a building’s architecture, but also its structural, plumbing, HVAC, and insulation systems. A well-drained roof can last for decades, but a poorly draining one can cause maintenance nightmares that, in some cases, lead to structural instability. In addition, designers increasingly rely on tapered insulation to achieve roof drainage, but sometimes misinterpret the energy code requirements for these systems. In this presentation, we will provide recommendations for effective roof drainage design and identify how to avoid common pitfalls with careful coordination. We will also discuss innovative tools and approaches to help designers calculate the energy performance of tapered insulation and optimize its efficiency. Throughout the presentation, we will include project case studies to illustrate challenges and practical solutions.
After attending this seminar, participants will be able to:
- Identify the options and key considerations when deciding how to drain a low-sloped roof.
- Understand tapered insulation’s limited contribution to energy code compliance.
- Recognize and avoid common pitfalls that inhibit proper drainage on some roofs.
- Coordinate between the architect, plumbing engineer, and structural engineer to design roofs with effective drainage.
