An average life span of a cement-tiled roof is approximately 50 years; Aussie Services Team can extend this to 60 to 70 years with a professionally resurfaced roof and roof restoration. The time limitation of 50 years is mainly due to erosion of the surface coating from original manufacture. Once the coating has eroded then the surface of the tile itself starts to deteriorate, it is after all, only sand and cement.
The results are often evident by the residue of sand in your gutters and the tile becoming thin and brittle. Once your tiles are at this stage, roof replacement is the only option.
Terra Cotta tiles have an average life span of approximately 70 years, although this varies greatly, depending on the manufacturer. Many examples of homes built in the late 1800’s and early 1990’s are still serving as a roof over people’s heads today. The early Terra Cotta tiles were shipped from France (Marseille Tiles) generally as ballast, in the holds of sailing ships. Tiles manufactured in Australia today reflect some this early history, Modern French, French Style etc.
As the component of a Terra Cotta tile is clay, and therefore requires laminating to provide strength, it depended a lot on the skill of the potter, both in his persistence to adequately laminate the clay, and his skill in the baking of the tile in the kiln.
Terra Cotta Tiles of today are highly consistent in overall quality, are manufactured with stringent controls, and most come with a 50-year guarantee.
Terra Cotta tiles should be avoided from installation close to coastal areas; the proximity of salt is a major deteriorating factor and can cause delaminating of the tile.
