Green Roofs Thomas Mickens Trudyann Buckley Victoria Mordan

• 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

• 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

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

Pros of Green Roofs • • Reduce and delay Storm Water Runoff. Improve air quality by reducing CO 2. Reduce heat in urban areas. Partially compensate for landscape lost to development. Buckley
