The ventilation of the roof

La-ventilacion-de-un-tejado

What should be consider regarding the ventilation of the roof?

Adequate ventilation of the roof, unthinkably, is an aspect not often considered when building a house, although it is an important factor that strongly determines its durability and efficiency.
Having this matter into consideration during construction stage will save expensive repairs in the future and will make the cost look insignificant.

As known, ceramic roof tiles are porous products and therefore susceptible to absorb and release water (known as “breath” of the material), that makes them ideal to regulate the moisture inside the building.

How to avoid moisture through the roof in a house?

For a good ventilation of the deck consider:

  • ensuring a good setting of the roof with special attention on the minimum air chamber
  • using Accessories and Roof components
  • using Ventilation roof tiles displayed in a proper array

This permits an easy drying of the roof tiles and eliminates moisture build-up inside the roof.

The roof ventilation will improve the conservation, thereby enhancing the maintenance of the roof. It also reduces the appearance of mosses and fungi, since a well-ventilated roof tile retains the water absorbed for a lot less time and therefore fails to provide moisture conditions that favour germination.

Why is it so important the roof ventilation?

Even if a roof is properly done, the humidity will have access inside. This is a phenomenon always present and technically unavoidable; therefore, the system used for the entire roof must provide a way for the condensed water to be removed from the inner layers of the roof.

Thus, ventilation becomes the key element for that purpose, which is achieved by providing a chamber beneath the roof tiles to force airflow re-cycle through for a continuous drying process.

WHY DRY INSTALLATION?

The fitting process of clay roof tiles is very important and it should considered at the time of choosing the material to be used on the roof.

Dry installation has significant advantages over conventional installation, as well as improving the performance of the roof during both summer and winter.

To ensure that the roof is installed correctly, air must circulate continuously in the space under the roof tiles. This micro-ventilation will allow air to enter via the eave lines and leave through the ridge lines, increasing through the use of ventilation roof tiles distributed along the roof.

During the summer, this air chamber will reduce the amount of heat received by the support for the roof tile and, therefore, the heat transferred into the building, reducing air conditioning costs.

In winter, indoor ventilation will prevent condensation from forming on the materials used to build up the roof (roof tiles, insulation, support, etc.), as they harm their durability. Furthermore, this condensation can affect the comfort of the building, producing moisture that is conducive to the formation of moss and bacteria that reduce the quality of the air inside.

With regards fittings, the use of mortar is not recommended due to its poor reaction with ceramics and the rigidity of joints. Roof tiles should be fixed mechanically or with adhesives made specifically for roof tiles, since these give the materials the necessary room to allow for the movements caused by expansion and changes in temperature.

To ensure their optimal installation, the Roof Tiles should be fixed to a support previously prepared with a double batten layout. Tejas Borja has a wide range of clay accessories and roof components as a solution for the ventilation, waterproofing, illumination and dry installation of roof tiles.

Ceramic roof tiles on pitched roofs

Why choose ceramic roof tiles for the roof instead of another material?

Ceramic roof tiles (clay roof tiles) are the result of the use and management of natural raw materials which by their nature have proven their quality over thousands of years. Our roof tiles are known for their durability, high strength, dimensional stability and high performance thermal and acoustic insulation of buildings.

Given their continued use over time, one can say that the roofs coated with ceramic roof tiles are a traditional element in the landscape. When thinking about building a house, the “roof” concept is associated with the bright colours of ceramic roof tilessafe and durable. A ceramic roof tile roof offers added value as an element of comfort in the home, with permanent protection and additional aesthetic value.

Nowadays, although competing with alternative materials, more and more the ceramic roof tile is said to be the best solution. This is due not only to their aesthetic features, but their properties and performance even under the action of the most severe weather conditions. Our products are long lasting and environmental friendly.

In our catalogue you will find wide range of ceramic roof tiles, different shapes, sizes, textures and colours, from the most traditional roofing tiles to perfectly Flat roofing tiles that can adapt to new architectural forms.

2nd Edition Ceramic roof tiles Arquitecture Prize

Reales Atarazanas-I-tejas

The 1st Ceramic Architecture Prize has been granted for the first time in 2014, to the rehabilitation project of the “Atarazanas de Barcelona”, of the architects Roberto and Esteve Terradas. The jury valued the careful rehabilitation of the roof, in this building of cultural use and of great historic value.

In the rehabilitation of the “Royal Atarazanas (Drassanes) of the Port of Barcelona” the ancient look of the roof was achieved by the products of Tejas Borja (Curved Celler® Roof tiles Centenarias®) and special big sized ridges that were glazed in a green color, and were reproduced for the occasion following the same design, regarding both shape and color, as the original ones.

[See Project]

The 2nd edition of the Ceramic Architecture Prize, in the category of Roof Tiles, is convened to value the architectonic productions that use the roof tile as building material.
