If you want a roof that will last up to a hundred years, you might want to look at tile. It's favored in warm climates, and the key to its status as a green material lies in its composition, its shape and its ability to be recycled.
"The curved shape helps with ventilation," says Jessica Clark, marketing liaison for the Cool Roof Rating Council.
Roofing tile comes in a wide range of colors, including those lighter colors that reflect less heat into the atmosphere. As an added eco-bonus, they're heavy: That superior thermal mass keeps the cool air inside on a hot, hot day.
