Read: Nigel Dunnett and Noel Kingsbury - Planting Green Roofs and Living Walls

A great book. Ever since visiting Norway and seeing the green roofs there on both traditional and contemporary buildings, I've been curious about their construction and benefits. This is a comprehensive resource on all the current knowledge, while also pointing out future areas for research. I had mostly considered the insulation benefits, so one of the biggest surprises was finding out how much green roofs can reduce water runoff - a huge benefit in overburdened urban areas.
