Compare the cost of green roofing with conventional roofing systems! Interested in green roofing but not sure how to determine its long-term costs and benefits, especially compared to traditional roofs? Stop wondering. Green Roofs for Healthy Cities (GRHC) with support from Tremco Roofing and Building Maintenance and the Athena Institute, are proud to bring you the GreenSave Calculator, specifically designed to help professionals concerned with sustainability. The GreenSave Calculator was developed by GRHC and the Athena Institute with funding by Tremco.


The soil in green roof systems acts like a sponge and absorbs excess rain water. Research has shown that extensive green roof systems can reduce runoff by up to 90+% annually (varies with climate, soil and pitch of roof). Green roofs reduce the impact of each new building on the municipal storm drainage system and surrounding watershed. They reduce flooding, erosion and artificial heating of water which helps preserve fisheries and other aquatic life. Green roofs reduce the need for on-site storm water management systems and according to Seattle based Magnusson Klemencic Associates, under certain conditions, can offset the cost of a green roof by 30 to 60%. When combined with an effective rain garden (bioswale), green roofs can make it possible to have zero discharge of rainwater from the site, therefore saving money by not having to connect to the storm sewer system. The LiveRoof® System can help you achieve LEED certification in several categories.


Zeager continues its good environmental practices by supplying a 100% recycled foam drainage product to the greenroof industry . Zeager's involvement started when they were approached by a leading greenroof designer - Roofscapes Inc. about their drainage product called Duradrain® which they had used as a drainage base for their various playground surfacing systems. Roofscapes incorporated this drainage product into their Roofrug® system as a drainage media and to promote root growth. Since then, there has been much excitement about this affordable system since it is excellent for retrofit situations requiring little or no structural enhancements.
