Green Roof Mat - Florida - Root Barrier and Cut Away View

Extensive Green Roof Mat System Cutaway Section
Here is an interesting photo of a Florida extensive green roof - 2-4" thick on a 5/12 slope (built in 2005) with a HDPE root barrier.  A portion of the vegetated roof has been removed for root barrier inspection and root behavioral studies.  The plants are growing in a soil filled woven mat and the roots are thick into the mat.  Once the roots reach the liner they turn and grow parallel with the liner's surface.
