A sliding roof for a convertible vehicle may include front, middle, and rear roofs, guide rails for sliding the front, middle, and rear roofs, and lift links for lifting the front and rear roofs such that the guide rail of the middle roof slides toward the guide rail of the rear roof and packaged adjacent to the rear of the vehicle. The sliding roof may include a latch which fixes a side pillar of the front roof to a windshield frame during operation of a sunroof and fixes the side pillar to the sunroof during packaging of the roof, thus ensuring the space of a rear seat of the vehicle.
