FIELD OF THE INVENTION The present invention relates to a temporary roof scaffolding system for protecting associated buildings, said system comprising: a temporary roof, a plurality of scaffolding elements being arranged next to each other and above each other to form at least one scaffolding bay, a plurality of columns, such as masts, a plurality of sliding arrangements to enable movement in the elevation direction of the columns, a plurality of locking means for stopping the columns from sliding in a downwards direction, wherein the roof is attached to the upper end of the columns, and wherein the sliding arrangements is arranged on, in or in connection with, the scaffolding bay. Furthermore, the invention relates to a method for raising the height of a temporary roof scaffolding system, wherein said method comprises the steps of: providing a scaffolding system, raising the columns in an upwards direction via the sliding means and increasing the distance between the lower end of the column and the ground, stopping the raising of the columns, positioning locking means in the sliding arrangement for stopping the columns from sliding down in a downwards direction. BACKGROUND OF THE INVENTION Within the area of temporary roofs and scaffolding systems it is well known that in some construction processes there is a need for regulating the height of a temporary roof in a scaffolding system concurrently with an associated building being built up in the height. Today, numerous solutions are available for temporary roofs in a height regulating construction process, however none of these solutions are optimal. In some construction processes, the temporary roof is built in the desired end-height from the start. This provides a temporary roof that actually does not protect the building underneath the roof in the start-stage of the construction process, since the building is too low to be protected by the roof, as the roof is too high to provide any protection, such as weather protection. Solutions where the roof is regulated in the height during a construction process are also known. However, these solutions require complicated systems, systems being permanently mounted or fixed in the ground, e.g. by foundation, but most importantly have the disadvantages of demanding support from an external force, such as an electrical power from e.g. drive units. Hence, an improved system and method, preferably an efficient and reliable system, for regulating the height of a temporary roof would be advantageous, and in particular an easy, resistant, mechanical strong, economical, sustainable system and method would be advantageous. OBJECT OF THE INVENTION It is an object of the present invention to provide an alternative to the prior art. In particular, it may be seen as an object of the present invention to provide a system and method for regulating the height of a temporary roof that solves the above-mentioned problems.
