A roof system for a vehicle having a roof opening with a movable closure. A stationary guide rails guide operating mechanisms that operates the closure. The operating mechanism comprises a first device configured to move a rear edge upwardly and rearwardly and a second device including a lever to move a front edge of the closure. A guiding slide in the guide rail is coupled to the first device and the second device so as to move the closure. The lever has a pivotal connection to the closure and, remote from the pivotal connection, a sliding connection to the guiding slide by a first guide member and a sliding connection to a first stationary guide curve by a second guide member during movement of the closure. A third guide member on the lever of the second device engages a second stationary guide curve during movement of the closure.
