Modern Green Roof Technology

Green Roof Service LLC’s latest project pushes the limits even further and arguably, I believe it will be the most interesting project in the world! In September, 2008, we installed 15,000 sf of green roof on the cruise ship Celebrity Solstice at Meyer Werft (Ship Yard), in Germany. We literally shipped a green roof from Germany to the U.S., and soon it will sail all across the world.
