Green roofs – vegetated roofs or roofs with vegetated spaces – make practical, economic and environmental sense, improving the appearance of a building, helping to restore biodiversity and delivering tangible benefits such as improved insulation, better acoustics and reduced risk of local flooding.  They have been adopted extensively in Europe and we are now witnessing a surge of UK interest in them as their contribution to the environment is becoming more widely appreciated.
