A clay tile roof is more than just a roof

Would you like to renovate your roof, replace the roof cladding and improve the thermal performance? The following information helps you in making the right choice and provides a compact overview of subjects concerning the roof.

Functions of roof

The roof is the main protective shell

The roof is the main protective shell of a house and decisively affects its appearance. During the planning phase some important factors, such as location or construction style of the building, need to be taken into account. The combination of pitched roofs and clay tiles, for example, is a symbol of the European culture. The large variety of shapes, formats and colours of clay roofing products reflects traditional craftsmanship and helps preserve the regional architectural heritage across Europe.

The roof protects a building and the people living inside against external influences such as cold, heat, storm, hail, rain, snow, and noise. Consequently, the roof is exposed to extreme stress and loads in the course of its use and it is a complex system of different components. In order to ensure optimal functioning, insulation, roof system components and roof tiles should be coordinated with one another. Wienerberger provides comprehensive roof system solutions from a single source to facilitate your decision.

Clay roof tiles – a general overview

A modern roof material

Wienerberger clay roof tiles are available in a wide variety of colours and shapes. Our portfolio offers architects and end customers complete energy-efficient solutions for new construction and renovation projects.

The production process is based on the four elements of earth, water, air, and fire. The natural components promote a healthy living climate, provide reliable protection for residents and are additionally recyclable.

The colour of clay roof tiles is determined by the natural composition of clay.  Each one of the different shapes with its typical, characteristic features has developed from regional conditions. The following main groups can be classified for roof tiles:

Tiles with interlocking

  • Flat tiles
  • Profiled tiles (Pan tiles, Tempest tiles, Reform tiles, Mulden tiles)

Tiles without intelocking

  • Plain tiles
  • Overlapping tiles (Hollow tiles)
  • Over and under tiles (Monk&Nun tiles)

Besides roof tiles for the roof area there are special ceramic accessories for the cladding of ridge, eaves, verges and hip. 

Why is a tiled roof the best choice for the roof?

  • Low maintenance: Roof tiles are solid and thus especially robust and dimensionally stable. They are insensitive to environmental influences such as heat, cold and frost. As a result, roofs covered with roof tiles require very little maintenance and guarantee a constant quality and beauty.
  • Durable: Roof tiles have a service life of 150 years. Reference: Untersuchung der Lebensdauer von Baumaterialien für Fassade und Dach, Extra Muros, Belgium 2009 (BE)
  • Flexible: Tiled roofs are especially flexible. In case of annexes and refurbishments, clay roof tiles can be quickly, easily and cost-efficiently installed or replaced.
  • Sustainable: If a building has to be demolished, roof tiles can be sorted by type. This allows their quick and easy recycling or reuse for new roofing, rooftop greening, road pavements and the improvement of the water absorption capacity of soil substrata.

Innovation

Fastening system

New patented Sturmfix 2.0: The innovative fastening system for roof tiles has been enhanced and therefore not only provides maximum storm safety on the roof but also can be removed easily if needed, for example in case of repairs or subsequent installation of a roof window.

Koramic AluGrip-Rol – Roof Grip Extreme Technology

A fully-aluminium ventilated ridge and hip roll with the patented Roof Grip Extreme technology by Wienerberger for use on ceramic surfaces. Three times higher bond strength on glazed, engobed and natural red surfaces compared to the commercial standard Butyl.

Flat tiles

Interesting possibilities

The development of roof tile models with flat visible surfaces and a straight, clear shape opens up new architectural design emphases and gives the buildings a new appearance. The use of these tiles on the façade also results in new interesting possibilities, with the application of tiles on both the façade and the roof being called “mono-cover”. See the example Actua at the end of the text.

Slate look

New possibilities in terms of look, shape and processing

The combination of the natural appearance of slate with the excellent properties of clay in one product provides new possibilities in terms of look, shape and processing. Innovative approaches in the design and production offer a great variety of different surfaces and appearances. See the example Rivius (UK) righte below the text.
