Abstract: Green Roof Blocks is a completely unique approach to covering the surface of roof tops with vegetation. The strategy of using self contained, durable 22 gauge galvalume sheet metal material containers, which can be easily installed and moved, differs from anything currently available in the market place. Much heavier plastic or polypropylene containers are currently on the market with limited success. My product requires no machinery to lift, nor any particular training to install. The use of rubber composite walk pad material as resting pads assures roofing system compatibility and warranty integrity. Thus no additional materials are required to separate the container from the roofing system. In fact, the walk pad material can be procured from different roofing system manufacturers allowing the roofing system manufacturer to provide a material acceptable to come in contact with the roofing material. This ease of use, choice of material and configuration, and system compatibility is unique to my invention.
