A roof component, in particular an inner liner for a vehicle roof, comprises a carrier layer which consists of a cured material, and a mounting structure. The mounting structure is formed by at least one undercut. There is further proposed a method of producing such a roof component, comprising the following steps: first, a forming tool is provided which consists of a first and a second tool part, an elastically deformable body provided on the first tool part being capable of being deformed between an initial position in which it is extended in a direction perpendicular to a general direction of extension of the roof component, and a working position in which it forms at least one protrusion which extends in parallelism to the general direction of extension of the roof component and at a distance from the first tool part; next, a curable material is introduced into the forming tool, the curable material curing to form the carrier layer while the deformable body is in the working position, such that the protrusion formed by the body is imparted to the carrier layer so as to form an undercut; subsequently, the forming tool is opened and the deformable body is transferred to the initial position, so that it frees the undercut in the carrier layer; finally, the roof component is taken out of the forming tool.

A roof assembly for a motor vehicle comprises a rim portion that guides a roof module towards an opening for a sliding roof cover. The rim portion has a water groove formed integrally with the roof module. In addition, the roof module may have an integrally formed spoiler adjacent the water groove.
