A well constructed clay or concrete tile roof should last more than 50 years. This is also an expensive type of roof covering as the materials are more expensive and require a strong frame to support the heavy load of the tiles. Tile roofs require very little maintenance and no preservatives. The tile is fireproof so fire insurance costs less for the entire life of the building. Clay and concrete tiles have similar physical properties and installation methods. Concrete is cheaper to make than clay and it can be made anywhere. Clay tile must be made near a clay quarry, so freight cost to the building site is often higher than for concrete tile.
