Terracotta tiles are among the most popular roofing materials used in Australia, their durability and old world charm has seen them remain a firm favorite for Australian homes. Originally manufactured in Europe and imported into Australia as ballast in Ocean ships, Terracotta tiles are now a major contributor to the Australian economy.
Although durable, Terracotta tiles require frequent maintenance. Concrete, which is used in the bedding down of the caps, does not stick well to the smooth surface on terracotta tiles. In this problem, lays the reason why this type of repair more often required, than their less durable counterpart concrete tiles. Moss and lichen are also attracted to these tiles which can be unsightly. We have listed the more common issues that you need to watch out for below so you can determine whether or not a restoration or repair of your roof may be required.
Cracked and broken tiles are a sign of an ageing roof and generally require replacement, usually as part of a larger terracotta tile roof restoration.
Loose ridge capping.
When the mortar or cement mix ages it will begin to crack and come loose, in turn this will loosen the ridge caps. This is a significant concern as inadequately secured caps can be blown off your roof in strong winds. Cracking and crumbling mortar is what you will notice first when this happens.
Rusted valleys and chimney flashings.
The glaze on a terracotta tile reacts with the old galvanised steel making rusty valleys and flashings a common occurrence on this type of tiled roof. It is also an idea to monitor your guttering as the same reaction can occur in them also.
Excessive moss and lichen growth.
Moss and lichen is attracted to terracotta tiles because of the carbon dioxide emissions present in the tile. They have no root systems and cannot harm the tile directly. Excessive growth can impede the flow of water causing ingress into the roof cavity and ceiling. Many people also dislike the look of the lichen making cleaning appealing.
Older glazed terracotta tiles can suffer from de-lamination. This generally occurs after the glaze gets old and cracking appears. Water seeps in under the glaze and freezes during cold mornings. The expanding freezing water pops the glaze off. This can also occur in salty environments close to the beach. While a moderate amount is acceptable, this can mean a roof replacement is in order if it becomes too widespread.
Terracotta tile roof restoration.
A terracotta tile roof restoration can make a remarkable difference to the look of the home. In brief a restoration is a clean down, mortar repair and flashing and valley iron replacement. Some dubious companies also recommend “glazing” the tiles with an acrylic sealant. This is not something that should be considered as the acrylic sealants used, while starting off as clear and attractive, quickly begin to go white or yellow in colour and also peel. A common claim is that fungicides present in these sealants when in actual fact a fungicide would evaporate off during the drying process.
