2 The roofing membrane provides the important waterproofing layer in every green roof. The compound prevents plant roots from appearing beneath the waterproofing membrane. The soil absorbs and retains storm water in a controlled manner to make the plants healthier. The surface layer of plant life is made to meet certain requirements of individual applications. Mickens

3 When rain falls on forested and open land, water goes through its natural cycle. Approximately 40% of the storm water is almost immediately returned into the atmosphere through transpiration. A Green Roof build-up reduces the water run-off to 50-10%. Mickens

6 Cons of Green Roofs Heavy! Can be pricey. Planting on a sloped roof needs extra erosion control, which is expensive. Maintenance is likely to increase compared to normal roofing. Buckley

7 Pros of Green Roofs Reduce and delay Storm Water Runoff. Improve air quality by reducing CO2. Reduce heat in urban areas. Partially compensate for landscape lost to development.

8 Materials Needed to Install a Green Roof N ote : B efore green roof installation can begin, hire a licensed structural engineer or architect to determine if any upgrades are needed. -Irrigation and drainage systems -Garden supplies (this includes soil) -Plants -Maintenance, transportation, and city permits -Time -Contractors -Fertilizer -Roof -Insulation Mordan
