Homeowners plant a ‘greenroof' for aesthetics and cooling

Is there vegetation spilling out over the edge of a roof near you? Are you thinking the property owner hasn’t gotten around to cleaning out his gutters? Perhaps it means that house is sporting a deliberately planted surface that makes a cool statement, both figuratively and literally.

Several high-profile buildings such as Atlanta City Hall and the Woodruff Arts Center have planted roofs, and they’re starting to show up on homes as well. These planted roofs are called "greenroofs."
Not “green roof,” but “greenroof,” a term becoming commonly accepted as a way to differentiate the planted roof from a roof made of green-colored building materials.
Some may want a greenroof just because it dresses up an exposed roof area, but a greenroof also serves two important environmental functions: It helps to slow down stormwater runoff and it provides an insulating effect, helping to reduce cooling bills.
