It is relatively easy to remove a LiveRoof module to access the roof deck.
First, using a flat bladed shovel, probe the planting to locate the container edge.
Then peel away some plant material. This is easy to do as the root systems of LiveRoof plants is fibrous and easy to separate (not at all like sod).
Using a sturdy pair of pliers, lift up and remove the exposed module.
Any additional modules may be removed by trimming around them with the handle of a spoon and lifting them up.
Once you are finished, replace the modules.
Important:  Never use sharp instruments around roof membranes.
