Rooftop terraces and green roofs have existed for several thousand years. This book fills the gap between demanding technical books and brief summaries in magazines. It explains in an understandable way how the technology of green roofing works, even covering the greening of steep roofs. The book demonstrates that expensive systems are not necessarily required, as relatively simple means can also green small roof areas like garages and outbuildings. It bridges the gap between extensive and intensive greening by favoring nature-oriented planting with native plants and differentiated substrate construction. Step by step, the reader is introduced to realizable solutions. Colorful graphics of planting examples for various roof shapes, including a plant list and substrate construction, complete this illustrative work.
