A tilt-up door for a building having an opening including a door frame with vertical track members, cam surfaces extending laterally from the vertical tracks at the upper portion of the tracks and a door sized to span the opening. The door can be pivotally coupled with rollers disposed within the vertical tracks and cam followers extending laterally from the upper portion of the door to contact the cam surfaces. When an upwardly directed motive force acts on the door the cam followers come into engagement with the cam surface to lift the door generally vertically and then rotate the door inwardly as the door is raised into an open raised position.
