It has been sometime since I looked into Green Roofs (2009). There is a fair bit of information out there but mostly with a fee attached. I now reside in Sidney B.C. and have started a 10' x 10' plus shed work shop with a 14' x 14' roof. I have been trying to locate person or persons in the Victoria, Saanich even up Island area that may have built a project like this. I have visited the one commercial lot at Shawnigan lake which supplies succulents. Perhaps you may know of someone or can point me in the right direction?
Call the Horticulture Centre for the Pacific, I believe their new building has a green roof -- they can likely put you in touch with the vendor / speak about their experience: Horticulture Centre aims to break ground on Mel Couvelier building - Saanich News (article from a couple years ago)
