Mike Moore, general manager and co-owner of Diggable Designs, an ALCC Sustainable Landscape Partner, learned some of the finer points of green roof design and installation when undertaking a project in the Highlands area of Denver. Homes in this neighborhood are narrow, and tower four to five stories high.

“I learned you have to do more legwork on the engineering side ahead of time,” says Moore. “You have to consider how heavy systems will be when wet and fully grown. When you add snow on top of that, you need to be sure the roofing structure can handle it.”

Each year ProGreen EXPO explores new ways to support attendees’ education goals and to keep the format fresh and engaging. For 2016, ProGreen planners discussed how the conference can evolve to meet the changing education needs of the green industry and address current challenges that it faces.
