What are the advantages of glossy glazed roof tiles for your building? In the meantime we are going to have a look at the clay roof tiles prices too.



What are clay roof tiles?

How are clay roof tiles made? Although clay roof tiles are old, but they are one of the most trusted roofing systems. They are designed mainly to keep out fire, wind and UV rays.

Clay roof tiles are prepared from baking molded clay at high temperature. They are molded into required texture and size, then comes the coloring and shading. Terra-cotta is a kind of special colored clay tiles which is very popular. Clay roof tiles are also referred to as Spanish tile roofs.


What clay is used for roof tiles?

Natural clay is still processed in large scale and by traditional methods. The roof tiles are created by filling tile moulds or pallets and are baked at a high temperature. Weight and appearance of the clay tiles are determined by how long it is baked and how high the temperature is.

Terracotta tile is a very popular choice in roofing. Due to their natural porous surfaces, and natural clay material – a moist substance; it lasts longer as it is a material that can withstand several years of weather exposure.

For instance, one of the traditional clay tiles used for roofing is ceramic. It consists of white clay and is manufactured under extreme compression methods.



What are glazed clay roof tiles?

Glazes are made up of ceramic pigments, mixture of clay in a small amount – and a large amount of sand. This leads to a thin, protective layer and smooth coating. Different styles of glazes can be made – matt or gloss. They are an excellent choice for roof tiles as they can be used for ceiling or roof tops.

Clay tiles are durable and you need to be careful while cleaning. For installation, repair or painting clay roof tiles, you should hire a professional roofer. Due to their natural materials, and energy efficiency; glazed clay tiles can be recycled and used as a good option in warm dry climate.


What are the benefits of glazed clay roof tiles?

What are the benefits of glazing clay tiles in building and construction? Generally, glazing helps maintain clay roof tiles in a water-resistant and eye catching color. This glassy layer on the surface of clay adds an enhanced level of resilience and endurance.

Clay roof tiles shingles come in a variety of textures – which glossy shiny tiles, in particular – add to the architectural style of building construction and show its unique and true colors. (Besides other advantages).


What is the difference between glazed clay roof tiles and unglazed clay roof tiles?

Clay roof tiles or terracotta roof tiles – which are a type of clay-based ceramic for roof covering – can be glossy and shiny. But what is the benefit of making tiles glazed?

There are many benefits in a glossy clay roof tile. Glazed clay or terracotta roof tiles use coatings with wide range of shades and colors. There are various styles of glossy clay roof tiles – categorized in semi-glossy and highly glossy terracotta or clay tiles. Because of their glazed surface, clay tiles are more durable and absorb less moisture.

Since unglazed clay roof tiles do not have this coating, they preserve their natural clay color. Unglazed clay roof tiles on the other hand; are not covered with this protective and glossy coating; therefore they are better used in climates with low humidity and little rain.

Unglazed clay roof tiles will absorb more water so the chance of tiles deterioration increases. They need extra protection so that they can be used – as a high quality material with an aesthetic look – almost everywhere.


Difference between ceramic and clay roof tiles?

Clay roof tiles vs ceramic roof tiles:

While ceramic and clay roof tiles both are eco-friendly, they have some significant differences, too.

As we mentioned earlier, chances of water absorption in clay roof tiles are higher. But the material used in ceramic tiles are white clay which provide more resistance, and is lighter in weight. It gives more resistant to harsh weather. Ceramic roof tiles are also a better option for low-pitched roofs. Ceramic roof coating provides deeper glaze and a better thermal resistance.

Glazed  clay roof tiles vs uPVC roof tiles



Although clay tiles – and their different types (glazed and unglazed) – have many advantages, but based on comparison between uPVC and clay tiles, they have some disadvantages too, which allow us to replace them with uPVC roof sheets. Please consider to contact our consultant teams at Sepid-fam Varna Company before choosing the best type of uPVC roof coverings. (Contact numbers are written at the end of the article).



  • Low Maintenance and repair

UPVC tile roof sheet is very long-lasting, and require less maintenance than glazed clay roof tiles. They are a great choice for various situations. UPVC roof sheets can last for decades. All of these have made uPVC tiles an excellent choice for commercial and residential roofs.

Since both of these construction materials are installed individually; any broken or damaged tile can be fixed or replaced.




  • Weight

Unlike glazed clay roof tiles, uPVC sheets are very light weight and easy to install. Clay roof tiles are relatively heavy. Not all building structures can withstand the weight. Therefore, before choosing to buy clay tiles; check that your structure can bear the weight of clay roof tiles.


  • Brittleness

UPVC or Unplasticized Polyvinyl Chloride roof tiles are incredibly strong.  UPVC roof panels are not fragile and will not break or get damaged – easily and during transportation or installation process. But clay roof tiles can be brittle and even crack under the pressure of being walked on. The pressure caused by your body weight can cause even the high material clay tiles to bend and crack.


  • cost

Being heavy and not easy to install is the main reason clay roof tiles are more expensive. In fact clay tile roofing is more expensive than asphalt, wood, and metal roofing.

On the other hand uPVc roof tiles are less expensive – compared to glossy clay roof tiles. they are lighter in weight and have lower infrastructure costs.


  • Water absorption

Although glazed clay roof tiles have a lower moisture absorption level than unglazed roof tiles; but still water absorption of clay roof tiles are high -compared to uPVC roof sheets. so it increases the chance of fungal growth and leads to faster deterioration. On the other hand water absorption of uPVC roof tiles are very low, since they are a good sealant and are overlapped completely at the time of installation to prevent leakage from roof.



  • Installation

To seal the roof and make sure tiles are waterproofed; you need specialized installation by a professional roofing contractor. The tiles must be carefully shaped and cut and have correct angles.
