Why Are Garden Roofs Beneficial?

Storm water management – Immediate water run-off can be greatly reduced as the plants, soil and retention systems built into a green roof creating water for use by the plants.  Water drainage is slowed down to drain systems, thus giving a measure of relief to overloaded storm water systems.

Urban Heat Island Reduction – the urbanization of the natural landscape from forests and farmland into buildings and roadways has caused average air temperatures in metropolitan areas to rise.  The plants can assist to mitigate the urban heat island effect. 

Filter - Green roof vegetation can help filter dust, nitrates, carbon dioxide and other potentially harmful substances from the air. 

Noise Pollution - Garden roofs can assist in reducing noise pollution.

Environment - Garden roofs can assist in energy savings and restore some natural wildlife habitats.

Protect Roof Membrane - Garden  roofs help to protect the roofing membrane from climatic extremes, UV exposure and mechanical damage, which may increase the life expectancy of the roof membrane. 

Types of Garden Roofs:

Extensive – Designed to be lightweight with soil depths as shallow as 3 inches and supporting only hardy plants.  Require little to no maintenance.  Access limited to maintenance.

Intensive – Designed to support a much wider variety of plants, shrubs and small trees.  Soil depths are typically greater than 8 inches.
