We are certified designers and installers of LiveRoof® brand Hybrid Green Roof Systems.

Generally used on flat roofs, a Garden Roof is created by installing a roofing membrane under dirt which is planted with a variety of vegetation types depending on geographic and climate requirements.

With technical advances in roofing materials and components, garden roof systems can now be successfully installed in most climates, providing an attractive design option.

Garden roofs are generally considered to be “intensive” or “extensive”, based on the weight of the system.

Intensive garden roof systems are relatively heavy, with deep soil to support a wide variety of small trees and shrubs. They require a high level of maintenance. Because of the high structural loading involved, intensive garden roofs are normally incorporated into the original building design.

Extensive garden roof systems have a shallow, lightweight growing medium, which can support only small plants such as herbs, grasses and wild flowers. They are intended to be low maintenance, and therefore require plants that are hardy, drought tolerant and preferably self-generating. Because the structural loading demands are low, many existing buildings can be retrofitted to accommodate extensive systems.

In general, the energy savings realized with garden roof technology depends on the climate, the type of heating/cooling mechanisms used in the building, and their particular efficiencies, and the energy sources, which are site specific. However, any reduction in energy demand means a reduction in the green house gas emissions associated with the production of that energy, resulting in positive effects on climate change and the environment.
