So when a 7,000-square- foot green roof was installed on a 20,000-square-foot addition to the First Unitarian Meeting House in Madison, Wis., it took a joint effort by a Wisconsin-based architecture firm and a Michigan-based horti- cultural company.

When all the modules are installed side- by-side, and the Soil Elevators are removed, an uninterrupted layer of soil and vegeta- tive surface extends above and across all the modules.

The LiveRoof system is a green roof installed with full-grown, mature plants thriving in a healthy eco- system, which is established on the day of installation. The design of the LiveRoof modules is horticulturally refined. Manufactured with 100 percent recycled plastics and compatible with different types of flat roof systems and single-ply roof mem- branes, LiveRoof modules establish a green roof as a thick, seamless planted surface rooted in a continuous, intercon- nected layer of soil. “When we’re talking about green roof maintenance, we’re talking about weeds,” said Dave MacKenzie, horticul- turalist and president of LiveRoof, LLC. “With LiveRoof, a green roof is a dense, seamless meadow of plants rooted in a n The vegetative system was supplied by LiveRoof, LLC.
