By increasing the pervious surface area of our densely built urban environments, we can reduce the amount of runoff and burden on the municipal infrastructure that struggles to handle the increasing runoff as development flourishes and severe weather events occur with greater frequency. The EPA has recently recognized that green infrastructure can be a more expedient and cost effective way to handle this urban problem when compared to digging up exisitng combined sewer lines and splitting them up: http://www.epa.gov/npdes/pubs/gi_action_strategy.pdf.
In addition to aleviating stormwater issues, green roofs can keep ambient temperatures lower through evapotranspiration, which translates to lower cooling loads for the buildings in our urban environments and keeps everyone's carbon footprint a little smaller.
If you're interested in learning more about the costs, benefits and implications of green roofs, there are places to go to learn from the experts. One such event is coming up soon in Baltimore April 30-May 2.
