Modular green roof system, apparatus and methods, including modular panels with complimentary edge systems

A modular green roof system comprising:

• a plurality of panels adapted to set onto a roof and to carry green roof materials,
• each panel having a bottom and sides extending upwardly therefrom to define an enclosed space for the green roof materials,
• the bottom being formed with drain holes therethrough and having an underside configured to permit water to flow under the panel on the roof,
• the sides having upper outer edge portions surrounding the perimeter thereof, and
• an edge system comprising an edge termination member releasably connected along said edge portions.

A modular green roof system comprising:

• a plurality of panels adapted to set onto a roof and to carry green roof materials,
• each panel having a bottom and sides extending upwardly therefrom to define a surrounded space for the green roof materials,
• the bottom being formed with drain holes therethrough and having an underside configured to permit water to flow under the panel on the roof,
• the sides having upper outer edge portions surrounding the perimeter thereof and
• an edge system between adjacent sides of adjacent panels to close the space therebetween,
• said edge system comprising flanges extending from said adjacent sides and an elongated connector strip releasably interconnecting said flanges.

A method of constructing a modular green roof system comprising the steps of:

• (A) providing a plurality of panels each having a bottom and sides extending upwardly therefrom to define a surrounded space for green roof materials,
• the bottom of the panels being formed with drain holes therethrough and having an underside configured to permit water to flow under the panel on the roof,
• (B) filling the panels with green roof materials,
• (C) positioning the panels onto an area of the roof in adjacent side by side relation such that sides of the panels at the perimeter of said area are exposed, and
• (D) connecting an edge system to the exposed sides of the panels to define a bounded area covered by the panels.
