  1. Green Roofs Thomas Mickens Trudyann Buckley Victoria Mordan

  2. How does a Green Roof Work? • 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. How Green Roofs Address Storm Water • 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

  4. Examples of Effective Usage • Lincoln Park Zoo –Chicago • City Hall –Chicago Buckley

  5. Examples of Effective Usage[continued] • Library –Kansas City • Asbury Woods Nature Center –Erie, PA Buckley

  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. Buckley

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

  10. Methods for installing a Green Roof • Hire structural analysis consultants. • Choose the site. • Obtain required permits from the Department of Construction and Permits. • Research green roofs designers and installation companies. • Determine the type of Green Roof. • Select Plants. • Work out irrigation system. and finally… • Pay for it all. Mordan
