Roof tiles have been around for more than 4000 Years. Even today it is natural, Building materials made from clay have become indispensable for the roofs of our houses.
Roof tiles are made from clay and hardened in a kiln. As a flat, Ceramic components are mainly used for this purpose, To cover houses.
There are several different types of brick, the – depending on their construction – can be summarized in three main groups:
■ Flachziegel sind plan und haben keinen Falz. Typical for this are beaver tails, the underside round, cut straight or pointed.
■ Profilierte Ziegel ohne Falz sind Hohlpfannen sowie Mönch-und-Nonnen-Ziegel (the combination bricks of the same name belong to the following group).
■ Profilierte Ziegelformen mit Ver-falzung sind am weitesten verbreitet. There are pans with only one side rabbet (Strangfalzziegel), with simple folds on the sides, Head and toe (Press interlocking tiles such as reform pan or double recess interlocking tiles) as well as multiple ring folds (Flat roof pan).
Colors for tiled roofs
A roof is a clearly visible element of architecture. It therefore has a very significant impact on the image of a house. The choice of roof tiles, not just the shape, but above all the color, is therefore of great importance. There are three different types of roof tile surfaces:
■ Naturfarbene Dachziegel gibt es in den typischen Farben gebrannten Tons. The spectrum ranges from light red to dark brown. This type belongs to the solid-colored bricks, in which color pigments permeate the entire material.
■ Glasierte Dachziegel haben eine stark glänzende, glass-like surface. The color palette is very wide and also includes modern colors such as light blue or turquoise. The glaze is used as a layer between 0,15 and 0,4 mm thick. It is used for sealing and surface finishing.
■ Engobierte Dachziegel werden mit einer Tonschlämme versehen, around certain firing colors like brown, but also to achieve brick red, when the clay material alone does not produce the desired color.
Special shaped bricks
Simple roof tiles are usually not enough, a roof rain- and make it stormproof. Because in many places, with. B. at ridge and verge, the transition to the gable wall, but also on the eaves, the transition to the masonry, special transition problems are to be solved. To make the work of the roofers easier and also to ensure real tightness, special pans were developed, which are referred to as shaped bricks. In addition to these supplementary tiles, there are also accessories, that is matched to the shape of the brick. This also includes ventilation elements, which are often made of plastic.
Pay attention to regional construction methods – Clay roof tiles were previously used in all regions, in which clay was won. In certain landscapes there are therefore very specific roof shapes and construction methods, which are considered typical of the landscape. Anyone who builds or wants to re-cover their roof, should, if possible, use these traditional construction methods.
