While Roof Gardens is clearly focused on the more traditional concept and practice of creating aesthetically pleasing garden space on flat roofs, the author addresses green roof technology and the industry's advances in the field. In particular, the is credited for testing and developing highly effective yet lightweight green roof components and systems, and case studies are presented.

Roof Gardens also offers a historical perspective and advice on site considerations, design elements, maintenance, and appendices of useful data and sources of supply and information.

Rooftop landscape architecture promises to greatly beautify our environment by greening our buildings. We highly recommend this easy to understand, invaluable reference for anyone interested learning about in-depth roof garden design and construction, from homeowner to city planner.

This book could be written only by someone who has a large experience and an enthusiastic approach not only to landscape architecture, but also to all elements needed to complete such project, as the roof garden. Roof gardens do not only mean "plants on the roof", they are result of many other 'bits and pieces'. For those who want to find a reason why and how to build or design an roof garden, and have a studious approach to what they intend do, this book is to be recommended by all means.

The book has history informations, projects, practical construction information, project details, informations about benefits and possible problems. But there isn't specific scientific or data informations. It is a very complete introduction book in using green in the roofs, but insufficient.
