A roof hatch for the roof of a vehicle, such as a large capacity vehicle. The roof hatch includes a rectangular shaped outer hatch frame, a rectangular shaped inner hatch frame received at the outer hatch frame, a rectangular hatch cover of glass over the open area defined by the hatch frames, a sealing frame between the outer hatch frame and the hatch cover. The hatch cover is mounted on the outer hatch frame by one of adapter angles, or manually adjustable or electromotively adjustable adjusters, with the adjustable adjusters allowing the hatch cover to be opened with reference to the outer frame. The choice of the ways for attaching the hatch cover to the outer hatch frame enable the roof hatch of the invention to be supplied in modules with the user selecting a particular version. In addition, where the hatch cover is openable with reference to the outer frame, a lock can prevent such opening, handles on the lock can open the lock. To prevent that opening, a movable blocking element can be operable to block movement of the handles for opening the lock.
