Tile lasts a long time - its expected lifespan is greater than the lifespan of the material on which the roofing rests. Tile won't rot or burn, and it can't be harmed by insects. It requires little maintenance, and comes in a variety of colors, types, styles and brands.
The biggest drawback to clay tile can be its weight. Depending on the material used to make it, tile can be very heavy - so heavy that extra roof support can be required. With some new materials, however, color is added only on the surface of the tile, and they can fade over time. Although most modern tile is kiln-fired into the tile making the color permanent.
Concrete tile roofing material is becoming very popular. Shingles, simulated wood shakes, lighter-weight tiles and concrete panels are being manufactured from a variety of fiber-reinforced cement products. Some are coated with plastics, enamels, or thin metals, and some contain recycled material. Although the products themselves are not yet recyclable, they are a good choice for durability and resource efficiency.
The advantages of concrete roofing are that they all have a long lifespan, require low maintenance, offer good fire protection and are resistant to rot and insects. Many tiles mimic the appearance of wood shakes, while improving on the durability and fire protection that real wood affords. It can approximate the look of clay tile or slate while mitigating the structural problems caused by the weight of the real material.
The only draw back to both tile and concrete is that the cost up front is higher than the other types of roofing. Over all maintenece is low so you will save in the long run.
