In 2012, an elevated roof-top turf deck system didn't seem to exist.  So, I decided to experiment and see what I could some up with.   Starting with an adjustable raised pedestal type system, similar to the existing paver systems, and then adapting it to integrate the synthetic turf seemed like the way to go. The overall design ended up working great - for about three years.  Then, the custom deck panels we created for under the turf areas began to fail.  While the system proved to be the right direction, it was time to find some better components.  See below for our revised solution - a system that is still going strong five years later and showing no signs of wear and tear!
