Rooftop Sedum

If you think there is nothing new under the sun, take a look at Xero Flor®. This progressive company sells unique green-roof packages to owners of commercial, industrial and residential buildings. Xero Flor’s technology, developed in Germany and adapted for our climate, involves covering rooftops with a shallow layer of mineral substrate that nurtures a self-sustaining ecosystem of low-growth, drought-resistant plants, or with deeper systems using a variety of perennials and grasses. The advantages of a green roof include added insulation as the green roof absorbs much of the sun’s heat; storm water retention and filtering; and reduced stress on roof membranes, which leads to fewer water leaks and longer life spans. And no, you never have to mow the roof.
