with John Thomas of Siplast 

Join CSI East Bay-Oakland for our April chapter meeting, featuring a presentation titled "Green Roof Systems", with roofing expert John Thomas of Siplast.

PRESENTATION DESCRIPTION: Green roof systems are typically described in terms of soil depth (intensive vs. extensive) or where they are assembled (built-in-place vs. modular). These are useful categories, but don’t address key elements of green roof design, such as drainage, water storage, roof slope, and other considerations. This presentation will review different green roof systems and components, and their use in meeting project goals relating to storm water management, integration with hardscape, and constructability.
