A roof system for a vehicle includes a fixed roof element, forming a fixed roof segment of a vehicle roof bounding a passenger compartment and situated in a rear area of the vehicle roof, a roof opening and closing mechanism, which allows a relative movement of a movable roof element in relation to the fixed roof element and/or a relative movement of a movable roller blind in relation to the vehicle roof. The fixed roof element is designed as a single-piece roof element having at least one impact energy absorption section and at least one receiving section locally distinct from the impact energy absorption section for receiving electrical and/or mechanical function elements, by which or in the interplay of which with other function elements a movement of the movable roof element for opening and closing of the roof opening and/or driving the roller blind can be effectuated.
