Concrete tile roofing has a somewhat shorter life span than clay roofing tile, an average of 30 years versus 50 to 60 years respectively. Clay tile roofing is more durable once installed, and some types of clay tile have lasted up to a century. Clay tiles are heavier than concrete, and they tend to place more stress on the underlying roof structure. This can lead to the need for repairs, so it is a factor to keep in mind when selecting clay tiles over concrete ones. Clay tiles are also more resistant to moisture from weather conditions since they are less porous than concrete.
