Through the daily dew and evaporation cycle, plants on vertical and horizontal surfaces are able to cool cities during hot summer months and reduce the Urban Heat Island (UHI) effect. Green roofs reduce the amount of stormwater runoff and also delay the time at which runoff occurs, resulting in decreased stress on sewer systems at peak flow periods Green Roofs not only retain rainwater, but also moderate the temperature of the water and act as natural filters for any of the water that happens to run off In winter, green roofs can retain between 25-40% of the precipitation that falls on them In summer, green roofs can retain 70-90% of the precipitation that falls on them With green roofs, water is stored by the substrate and then taken up by the plants from where it is returned to the atmosphere through transpiration and evaporation Prolonging the service life of heating, ventilation, and HVAC systems through decreased use Using recycled materials in the growing medium Prolonging the life of waterproofing membranes, reducing associated waste Green roofs can contribute to landfill diversion by: Urban greening has long been promoted as an easy and effective strategy for beautifying the built environment and increasing investment opportunity GRHC members are an excellence source of green roof expertise, and a resource manual is available from GRHC's Green Infrastructure Store. Hence, all technical performance details provided will vary by region, climate, building, design, and green wall type.

Green roofs attract beneficial insects and birds, and butterflies when the plants are in bloom. “Although green roofs are not able to fully replace ground-level gardens or naturally forested areas, they can nonetheless increase biodiversity in an urban area like our campus by providing habitat where there would otherwise be none. “Arnett Hall is new and exciting for a variety of reasons, but from a horticultural perspective, one feature that stands out as particularly cutting edge is its green roof,” explains master gardener Jeff Daley.
