Abstract: The present invention is directed to a system for a green roof that allows a green roof to be used more affordably and in a broader range of situations than currently available. The system includes a network of grow chambers suspended above the roof. The network of grow chambers are interconnected by a grow matrix. The grow matrix is formed from a material such as wires, which also allow the plants in the grow chambers to climb and expand over the roof. The system also includes structural supports to provide stability to the system and to suspend the matrix in areas where there is no grow chamber. The system can be installed on different roof configurations, including pitched roofs, and need not be installed over the entire surface area of the roof. In addition, the system can include irrigation in the form of sprinklers, drip watering, or water reservoirs.
