The roof covering is used as the roof cladding or. Called roof waterproofing. It is of enormous importance in terms of construction, but also legally in various areas. A wide variety of materials are used as the roof cladding, which in turn depends on many factors in the individual case. We have therefore put together some important information about roof cladding for you below.
Definition of the roof membrane
The roof skin is the cover or seal of the roof suburb. As can be seen in the two terms "incourse " and "seal ", a first distinction is made here for roof shapes.

Materials for the roof skin
Which material you can use as a roof skin depends on numerous factors. The material itself is almost no limitations.
- Natural stone (slate)
- Roof tile (roof pans)
- Fiber cement roof panels (Eternit, Berliner wave or corrugated cement)
- Grass, reeds
- Metals (stainless steel, non-ferrous metals like copper)
- Bitumen and tar products (roofing cardboard (16.48 € at Amazon *))
- Plastics (liquid, as foils, acrylic glass or shingles)
In the case of flat roofs, a special shape with a green roof can be added. The substrate layer (on which the plants grow) is not the roof skin, rather it is a component of the roof skin, which in this case is multilayered.
Criteria to be met
Which materials are ultimately used depends on numerous aspects. On the one hand, there are of course legal requirements to be observed. Then the load-bearing capacity of a building and the roof structure also play a significant role. Thermal insulation properties have become just as important today, not forgetting sound insulation.
The traditional roof skin
However, there is also the traditional approach to the roof cladding. In northern Germany these are mainly thatched houses, in southern Germany (e.g. Black Forest, Alps) wood shingles can often be found, while in low mountain ranges with slate deposits (Swabian Alb, Moselle, Altmühl) slate roofs are steeped in tradition. Today, however, some of these traditions are processed far beyond the regional borders.
Legal information about the roof cladding
The roof membrane is also an important element in the statement of ordinances and laws. In building law, for example, the eaves height, which may not be exceeded or fallen below, depending on the region, can be defined using the roof cladding: the eaves height is at the interface between the roof cladding and facade, i.e. above a possible substructure (roof truss).
Roof skin and fire protection
The same applies to other laws, for example fire protection. Depending on the fire protection class, certain fire protection values must be observed in a building. It also describes exactly how far fire protection measures have to reach or can. So there are fire protection classes in which a fire protection measure must be kept under the roof skin. In this case, this fire protection action also penetrates the underlying roof truss.
General selection criteria for the roof skin
If all points are considered, only some possibilities remain in the choice of suitable roofing. These often depend on the financial expenses. Because concrete axes certainly have a significantly higher weight than bituminous shingles. Accordingly, the roof truss must reach the respective load capacity and resilience.
Modern demands on the roof skin
In modern times another important criterion are properties for the use of solar energy on a roof. Here, too, the weight plays an important role. However, solar systems are also influenced by the shape of the roof.Tips & Tricks Even before you start building, you should find out which roofing materials are available in your region or city administration or. Community are possible. The local building authority is required to provide you with relevant information.
In the house journal you will of course also find many articles on the various roofing materials such as the slate covering.
