Green Roofs: Efficient And Pretty, Too

Greening your roof could save you 25% on energy bills, help clean the air, and provide a cool place to relax all at once.

"Anyone building a new home or business -- or renovating an older structure -- could slash their heating and cooling bills by 25 percent, double the life of their roof, reduce stormwater runoff, help clean the air, create urban wildlife habitat, and make their building look fabulous by changing just one thing. When it comes time to replace ugly asphalt shingles or a tar and gravel roof, do it with what's called a 'green roof.' It's a shallow expanse of garden that can be installed on any structure--house, office, school, factory, shopping mall."
