A vehicle roof with a roof opening disposed within a fixed roof outer skin of a vehicle and a cover (10) to optionally close and at least partially open the roof opening. To at least partially open the roof opening, the cover can be both tilted out from a closed position at its rear edge and displaced in the driving direction to the rear. The cover has at least one locking lug (12a, 12b) in the region of its leading edge (14) that engages, from below in a closed position of the cover, into a support element that is stiff in a direction perpendicular to the roof outer skin. Additionally, the cover is formed at its rear edge such that engagement from below under the lateral and rear areas of the roof opening does not occur in the closed position.
