While green roofs may be universally accepted as wonderfully sustainable landscapes for a myriad reasons, the thought of installing one atop your own home may nevertheless seem daunting, expensive, and difficult to maintain. But the folks from Toyota Roof Gardens ^[5] (a subsidiary of the Prius-creating car company) have solved your green roof installation qualms with a tile-based system that’s as easy as laying down carpet. The TM9 self-watering turf tiles measure twenty inches square, and connect directly to irrigation systems, making them entirely self-watering. And at a slim 2 inches thick, the tiles lightweight and do not require any additional structural upgrading to your existing roof.

At only $43 per tile, the TM9 system provides a modular, easy-to-install, cost-effective option for green-minded homeowners. In terms of maintenance, the tiles need only be cut once a year, thanks to a special breed of Korean velvet grass. And of course, like all green roofs, you’ll rest easy knowing that your easy installation is providing a natural cooling effect, thermal insulation, and a little extra flora in your home environment.
