If a house roof shows damages, a roof renovation is to be advised.

One understands by a roof renovation the repair of a roof and to all in addition to belonging components, as for example the roofing, the roof framework and the gutters.

Many do-it-yourselfers would like to try the renovation of her house roof themselves what is not necessarily to be advised, nevertheless. A roof renovation should be carried out in general by an expert, then a mistake occurs the layman with the repair of his roof, this can appear under circumstances only after some years and it is already too late in many cases, because the roof can show at that time quite considerable damages by the wrong renovation. Besides, the work on a roof slant shows a not unimportant safety hazard for the in experienced do-it-yourselfer.

For these performed reasons it is always advised to the layman to instruct a professional company for the roof renovation.

An other very familiar and very modern method of the roof cleaning is the application of a special cleaning agent which removes the contaminations on microbiological way. With a such special cleaning agent it concerns germs which attack the mosses, lichens and fungi on the roof very actually without damaging, besides, of the roof coating or even to the roof tiles. This kind of the roof cleaning shows a very ecologically friendly method.

All the same for which kind of the roof cleaning one decides at last, it should be carried out anyway on time, because strong contaminations not only to the roof damage, but also the purse. The repair of a roof is considerably more expensive and costlier, than a roof cleaning.

The first kind of the roof cleaning is carried out with the help of high pressure. On this occasion, warm water is sprayed with a special steam emitter under high pressure on the roof at what the contaminations by the high pressure of 230-280 bars mostly easily take turns.

If a roof is strongly dirtied, a roof cleaning should be carried out to protect the roof in the long term against damages.
Contaminations on a house roof look not only neglected, but can also destroy the protective coating of the roof tiles. For example, this damage can happen by the mosses which have settled on the house roof.

The mosses store water which dissolves bit by bit the surface layer of the roof tiles. If the surface layer of the roof tiles is cracked or is porous, the humidity can penetrate into the roof tiles which can cause blowing offs or tears in the roof tile in frost. As a result the roof tile must be substituted mostly, because a cracked or jumped roof tile offers no more sufficient protection for the lying underneath roof layers, as for example the isolation of the roof framework any more.

The binding agent is responsible mostly for this very smooth surface in the colour and after the entire drying of the roof colour the surface structure of a membrane with closed pores resembles. The basis for this smooth surface is to be searched in the molecular structure of the used binding agents and big molecules passed away for the bubbles from effect of the roof colours are responsible. On this very smooth surface mosses, lichens and fungi have also looked in the long term to settle no chance. Hence, a lasting protection is guaranteed with a modern roof colour against the soiling of the roof.

These concrete roof stones are found in the specialised trade either with smooth or granular surface in different dimensions, forms and colours. On this occasion, the numerous models which own a dirty-unfriendly quality are also offered. The roof roofing with concrete roof stones is also possible with a roof inclination of 22 °-90 °.
The roofs with only one low inclination from 2 ° to maximum 35°, can be covered with metal elements of copper, titanium, zinc, aluminium or galvanised steel metal.

A fallen out, in colour roof coating gives an individual appearance to the dwelling house.

If on the basis of numerous contaminations, as for example mosses, lichens or fungi a new roof coating stand in a queue, the house-owner, beside the typical colours can decide on a house roof, also for a fallen out, individual roof colour.

A roof coating is carried out as a rule in several working steps. In the first working step damaged roofing tiles are substituted, perhaps, with new ones. Then the roof is released mostly with the help of a steam emitter with 230-280 bars from the contaminations. On this occasion, the expert uses exclusively pure water without chemical cleaning agents. In the next working step a new priming on acrylic base on the roofing tiles must be raised, so that the roof coating sticks later also properly and is not washed away after the first stronger rain or by the solar irradiation in summer bursts. The priming is colourless as a rule. If the priming is well dried, the first layer of the new roof coating can be raised in the desired colour. This process is repeated mostly from two to three times, so that the roofing tiles are also covered optimally by the new coating and are sealed.
