Toronto Eco Roof system
New or Retrofit
Green roofs can be designed to be an integral part of a new building, or can be installed later on an existing building. When a building is designed with a green roof system, there can be several benefits. For example, the building is designed to provide the necessary structural support, and won't require reinforcement later. Also, the building can be designed to take advantage of the aesthetic value that a green roof can offer by providing viewing areas.
York University installed a 30,000 square foot green roof during the construction of the Computer Sciences Building in 2003. The green roof is not accessible. It has been monitored by the Toronto Region and Conservation Authority to determine the quantity and quality of stormwater and quantify other benefits of green roofs..ca/greenroofs/images/york_350.jpg" alt="Toronto Eco roofing" />

An example of a retrofit is the intensive 704m2 green roof on ESRI Canada Ltd. 12 Concorde Place. It covers 100% of available roof space on a commercial building, and it hosts 52 plant types including sedums, grasses, flowers, herbs, shrubs and trees. .ca/greenroofs/images/esri_350jpg.jpg" alt="Toronto Eco roofing" />
