Tiles roofs, also called “Spanish roofs” are made form terracotta clay tiles and are widely used in some areas of the country like southern California. They are often used in the southwest of the United States because they are more efficient in blocking the heat from the sun than asphalt shingles. Tile roofs are not just the terracotta shaped clay tiles you might have initially thought of. They now come in a wide variety of colors and shapes to fit almost any design. The best part of tile roofs is their durability. It is not uncommon for a tile roof in the southwest to last 100 years. There is a manufacture that offers a 75 year warranty on one of their tile roof options.
