A fire service elevator has an elevator cage, which includes a cage roof, wherein the cage roof has a seal in which at least one drain is arranged. The drain is so arranged in the seal that extinguishing water collecting on the cage roof in the case of a fire flows away from the cage roof substantially only via the drain.
