Three years ago we replaced the asphalt shingle roof on our house with Brava Tile shingles and at the same time re-decked with solar barrier decking. Cut our summer electric bill in half. Winter bill cut by 1/3. Ours was the second house in Dallas to use Brava Tile. People visit our house to see the roof. Two weeks ago a couple from Cedar Rapids Iowa flew to Dallas to see our roof.
Brava Tile looks like ceramic Spanish tile but weighs less than standard asphalt shingles so you don't have to strengthen a roof to use them. Brava Tile also has roof tiles that look like slate and ones that look like cedar shakes.

(Our house was designed/built by a couple from Los Angeles and it doesn't look like a typical Dallas house.)
