Moisture protection includes, in addition to the use of foil, tight tile laying - if there is no gap between the tiles and the roof slope is at right angle, the water flows downward due to gravity and does not get under the tiles. Proper placement and fixing of roof tiles is also a basis for protection against wind. Röben ceramic tiles are an overlapping type of tiles, which means that they stay on the roof under the weight of successive overlapping rows, with the help of locks.

The locks are on the side and on the top of the ceramic element - each consecutive tile must be "pinned" to the next one. Contrary to some opinions, the tiles do not need to be fixed using a drill or hammer.

Basic rooftiles are fixed by their overlapping locks and clamps - fastening them to the slope, using a special device.

In case of clamping, special attention should be paid to the carefulness of performance.

It may sometimes happen that, for the purpose of speeding up the roofing works, the clamps are used only on the outermost roof tiles. This is a bad practice – safety requires that clamps should be used for the whole work area.

It is usually advisable to clamp (tie) every third tile along the slope, unless the specificity of the roof or the frequent occurrence of gusty winds require other solutions. (For very steep roofs, e.g. mansard, it is advisable to clamp all roof tiles acRoss the entire roof, as the rooftiles do not press the row beneath with their mass, as they do on roofs with smaller slope angles).
