History of Green Roofs

Green roof systems are ancient technologies that are once again being considered for a variety of modern applications.

The history of green roofs date back thousands of years. The most famous green roofs were the Hanging Gardens of Babylon, considered one of the Seven Wonders of the World. These terraced structures, constructed around 500 B.C. were built over arched stone beams and waterproofed with layers of reeds and thick tar. Soil, plants and trees were then planted.

The most recognizable green roofs in North America were installed in the 1930's on Rockefeller Center in New York City. These rooftop gardens continue to flourish today after nearly seventy years of service.
