What can a mat of low-growing plants do to help reduce global warming? Ask green roof advocates! Green roofs are cropping up all over urban areas. And, no, you don’t have to mow them.
They may not be visible from street level, but green roofs are quietly bursting into bloom all over the United States, helping to reduce environmental problems in urban areas. They reduce water runoff, help cool down summer air temperatures and save on heating and cooling costs for the buildings below them – as much as 10 to 15 percent.
According to the American Society of Landscape Architects (ASLA), green roofs also make the air cleaner.

Chicago, Atlanta and Portland, Oregon, lead in urban green roof installations, while in the Boston area, the Seaport World Trade Center in South Boston and Boston City Hall have green roofs.
And although this green option costs more than a conventional roof – $10 to $20 per square foot versus $5 to $10 for traditional roofing material – the plantings help protect the roof from extreme temperatures and ultraviolet radiation and ultimately increase the roof’s life.
