The Basics of Glazed Roof Tiles and Its Most Common ApplicationsJanuary 10, 2022


If you are in the planning stages of a home renovation project, and you have decided to reroof your house with terracotta roof tiles, then you should know the difference between glazed and unglazed tiles before you make any final decision. Not everyone knows that not all terracotta tiles are the same. There are glazed and unglazed terracotta roof tiles, and knowing the difference between the two will help you make the best decision for your house.

Glazed and Unglazed Terracotta Roof Tiles

There are many benefits when choosing to renovate your home with terracotta roof tiles, mainly because they are environmentally friendly, as they are made from natural clay and last a long time. But before making a final decision, here are the differences between glazed and unglazed terracotta roof tiles:

Glazed terracotta roof tiles – glazed roof tiles have a coating that can consist of a wide range of colours and shades. Glazed terracotta roof tiles can come in a variety of finishes, for example, semi-glazed and highly glazed. The benefit of glazed terracotta roof tiles is that they are more durable and have a lower moisture absorption level than unglazed roof tiles.

Unglazed terracotta roof tiles – unglazed roof tiles are not covered with any pre-coating, which gives them a rustic appearance that some people desire, as it preserves their natural clay colouring. However, unglazed roof tiles are best used in areas with little rain, since they are not covered with a protective coating and are porous, which means that these will absorb water and deteriorate quicker than glazed roof tiles.

However, sealer can be applied to unglazed terracotta roof tiles, as these can also be painted for extra protection and to meet the aesthetic needs of a home.

Pros and Cons of Glazed and Unglazed Terracotta Roof Tiles

The main difference between glazed and unglazed terracotta roof tiles are their appearance, water absorption rate, and durability. With glazed roof tiles, there is a wide selection of colours to choose from that can be glazed onto the tiles, resulting in a shiny finish. Also, this covering, adds to the durability of roof tiles.

On the other hand, unglazed terracotta roof tiles do not have a protective layer, which leaves the surface of the tiles porous and exposed to wearing and weathering. This also makes them a bit more fragile and more easily stained than glazed roof tiles. However, unglazed roof tiles can have sealed and paint applied to add protection and to meet the aesthetic needs of a home.
