Green roofs serve several purposes for our environment and buildings. Utilizing rainwater, providing excellent insulation, and creating a habitat for birds and butterfly to name just a few for urban locations.
The idea of Green Roof Design and its creative potential is almost limitless…given the type of dwelling being constructed upon, and not limited to only flat roofs; planting atop for residential interest has increased exponentially in recent years. Currently, Toronto has a growing number of affordable solutions to get more people easier access to going green.
The persuasion towards rooftop gardens and green walls has usually been driven by energy solutions that save money and structure costs on the long run of the dwellings life. However, more residents see the potential for growing their own vegetables, or creating a green space that may not have been possible on the ground level, or, a green wall as an aesthetic enhancer to the existing design + architecture of the dwelling.
Some differences are listed below.
Urban air temperatures are increasing reaching high temperatures on typical black and white rooftops. There are two types of green roofs: intensive roofs, which are thicker and can support a wider variety of plants but are heavier and require more maintenance, and extensive roofs, which are covered in a light layer of vegetation and are lighter than an intensive green roof. The second choice, a lighter layer; is one that can be adapted for home owners with flat roofs, or for older homes or Garages where rooftop weight is a concern. In most cases you are working with an existing structure system; and to get started, an engineer must assess the building. New building codes are being updated frequently in Toronto to accommodate this interest in Green Roof and Green Wall construction.
A successful planting on the roof or wall begins with careful planning and a visit with your local green architect.
