Flat Roof Terrace Green Roof
Vertical Landscape Architects Inc. has designed and will install a 65 sq. ft. irrigated green roof for a modern residence in Toronto. The 2nd storey green roof terrace will be extensive (less than 4″ of growing media) due to weight limitations and include mostly native plants to provide visual interest all year long. Concept sketches of the green roof layout and irrigation system with details are shown below. More pictures of the finished project will be added soon.
Sloped Residential Garage Green Roof
The following picture shows an extensive green roof assembly on a 215 square foot sloped garage roof. Lightweight growing medium is kept in place and protected from wind and water erosion with a special slope retention system (beneath) and a pre-vegetated green roof mat. The pre-vegetated mat also provides an immediate green effect for visual enjoyment and reduces the frequency weeding maintenance needed during the first year. A water retention layer beneath the growing medium distributes water more evenly on a sloped roof and reduces the need for supplemental watering during hot summer months. An automatic irrigation system was not included as part of the design. Diverse plant types that can withstand drought are included to provide year round visual interest and attract desirable insect and bird species. This green roof project will greatly improve the homeowners enjoyment of their back deck, which the garage roof was directly beside. The green roof is expected to reduce the ambient temperature on the nearby deck and the temperature inside the garage all summer long. Neighbours will certainly enjoy views to this garage Green Roof as well. Be a good neighbour – install a green roof!
