The main purpose of a green roof is to maximize water retention but it also must minimize costs in construction,
be somewhat light-weight and be easy to maintain. It must also be sustainable and aesthetically pleasing.
This is all possible with the Purple-Roof concept.
Purple-Roof is a non-proprietary concept that is available through many manufacturers. The Purple-Roof concept provides an instantly vegetated roof that utilizes vegetation as a tool to protect the soil and resist runoff. Purple-Roof can successfully retain the most water and minimize and/or eliminate fine particle and fertilizer runoff. The elements used are 100% natural materials and Purple-Roof utilizes conventional drainage plates to breathe. The goal of the Purple-Roof concept is to mimic nature and create a living root zone that is self-supporting.
