−	;System Summary: The '''LiveRoof Lite System''' for ''Protected Membrane Roof Assemblies'' ("inverted" roofs) is typically used on retrofit projects when the roof is engineered with only 15 to 17 pounds per sf for the green roof component. Its soil depth is a full 2-1/2 inches, enough to support many low growing succulents and a limited number of accent plants. It is generally not recommended for hot climates.
−
−	:The '''LiveRoof Lite System''' provides a modest level of storm water management and may provide modest energy savings, especially if attentively irrigated during the warm season. It also meets greenspace requirements in many instances, and provides limited biodiversity. Its plants will support pollinators such as butterflies and honeybees, and the plants that grow in the Lite System are diverse enough to support patterned designs.
−
−	~~:The plants used in the '''LiveRoof Lite System''' include a fairly broad range of low growing Sedums (mostly fine and medium-textured), as well as a few Alliums, for vertical and textural interest.~~
