On green roofs
I struggle to see much 'green' about green roofs. What you are doing is going to great expense to make a roof look like a meadow. Which it's not - it's a roof. You have to beef up the rafters because of the extra weight. You have to tank the roof with a hi-tech (and not very green) waterproof layer laid over sheathing ply - so you basically have something like a felt roof at this point - and then you have to go to great lengths adding edging materials to ensure that your organic matter doesn't slide off and become a large mound of slurry. Oh, and it all costs a fortune.What is the point?

Is there no benefits to environmental aesthetics? Increased habitat in places overrun by urban development? Connection to a natural world we've covered in concrete and shingles? Decreasing storm water runoff? Decreasing the impacts of emissions? Reducing noise? Decreasing the urban heat island effect? Hmmm....seems like there are some green benefits you overlooked.
Another thing.... What about growing your garden greens out there! Lettuce, cucumbers, etc. I think the term is edible landscaping.
