TOBYHANNA ARMY DEPOT, Pa. - Workers from Silvercool Roof install the second of four green roofs on Building 11's Wing C.

Each green roof will cover about 14,000 square feet with about 1,500 pre-planted modules of plants.

The green roofs will improve energy efficiency, extend roof life, reduce storm water runoff and improve storm water quality. They are composed of a root barrier, a water-handling system, soil and plants picked for their ability to thrive in the region's climate, and the green roof system.

The modules contain plants of the Sedum family and include Angelina, Love Triangle and John Creech.

The green roof technology offers a flexible and modular design that can be adjusted and rearranged after installation. The first green roof was installed on Wing A in 2006. All four wings will be completed by the end of December.
