Abstract: A method is provided for mounting a roof assembly into the interior of a vehicle having a fixed roof and an interior roof cover shell. A substrate is attached to the lower side of a frame. A roof opening is made in the vehicle roof and in the cover shell. The circumference of the shell opening is made slightly larger than the outer circumference of the substrate, at least at the position of the inner circumference of the cover shell after assembly. The frame and the substrate attached to the lower side thereof are mounted to the vehicle roof and the outer circumference of the substrate is fixed to the inner circumference of the cover shell opening. The substrate and cover shell may be demounted as a unit before a flexible cover is provided over the lower side of the cover shell and substrate. The unit of substrate, cover shell and cover is mounted again to the frame and vehicle roof.
