Select a membrane with high puncture resistance
Establish redundancy in the waterproofing assembly by overlaying splices
Design the assembly to provide slope and proper drainage at the membrane level
Incorporate protection above the membrane to aid against root growth and possible puncture
Incorporate a drainage layer and a root barrier to influence root growth away from membrane
Select proper growth media for the type of roof garden intended
