Residential green roofing system for sloped surfaces


We will invent a stucture that supports plant growth on existing sloped roofs which will be used by homeowners seeking to reduce their home's negative environmental impact. The structure will fit any existing roof, provide up to 95% natural shade, reduce storm water runoff by at least 50% for individual rainfalls under one inch, cause no lasting damage if removed, and be aesthetically pleasing. The average cost of the roof for a single-family home will be $400.
