1. Get your roof evaluated by a structural engineer or someone experienced in the installation of green roofs. You want to know at least three things: Can my roof bear the load of the planting containers? Is the pitch of my roof too steep? how will the existing heating/electrical/water systems be affected?
2. Decide on the kind of roof (intensive/extensive) you want to install – this will determine everything from your maintenance requirements to what kind of plants you can grow.
3. Decide on whether you want to try and install it yourself or find a local company experienced in doing it. Are you going to build it from components or are you going to use pre-planted modules? If I were handier – and owned a garage – I would use it or a shed as a trial run. A working roof is kind of important…
4. Share the information – blog about it, post to cityfarmer or similar venues – and encourage others to follow suit. One roof at a time can make a big difference. See some case studies here and here.
