The team have recently topped a beautiful building with one of our wonderful green roofs. This roof is very visible from a window in house which means our client can enjoy it year round.
This photo shows the edge detail of the roof. One good way, as here, is for the roof to be build with an upstand so the green roof can just be laid down in what is effectively a tray. If your roof isn’t like this there are other options such as attaching retention bars round the edges.
