Which of the following is NOT a common material used in tile roofs?

Wood is not a common material used in tile roofs. Tile roofs are traditionally made from materials that provide durability and a certain aesthetic appeal, such as ceramic, concrete, and slate.

Ceramic tiles, often associated with clay, are widely used due to their strength, variety of styles, and weather-resistant properties. Concrete tiles are popular for their cost-effectiveness and longevity, offering a durable option that can mimic the appearance of other materials. Slate, a natural stone, is highly sought after for its elegance and lifespan.

In contrast, wood is more commonly associated with shingle roofs and does not possess the same water resistance or longevity characteristics as tile options. This distinction in material usage highlights the unique properties and application of tile roofs, where water drainage and resilience to damage from weather events are paramount.
