Designing Low Slope Roof Drainage for Climate Change/ Severe Rain Events (1.5 LU|HSW)
Roof drainage systems for low slope buildings have based their design requirements on a “60-minutes, 100-year storm”. Code requirements for sizing roof drainage do not plan on severe rainstorms / climate change. This presentation will focus on why designers and contractors may be contributing to a potential roof collapse and solutions for improving roof drainage. The presentation will discuss the flaws in the current code, where low slope drainage design can improve by designing low cost upgrades and potentially save lives by avoiding a roof collapse.
