I’d like to know how to create a rooftop garden


Indeed there are many good reasons to build a rooftop garden, or a so-called “green roof”—whereby layers of soil and plants on top of homes and buildings provide a host of environmental “services” for the living space below as well as for the surrounding ecosystem. Unlike traditional roofs, green roofs thrive on (and filter) precipitation, decreasing the amount of pollution-laden stormwater run-off draining into our waterways. And thanks to the process of photosynthesis, the plantings create oxygen, cleanse the air and absorb carbon dioxide before it gets into the atmosphere and adds to our global warming woes.
