Abstract: A roof rack apparatus for a vehicle includes a roof rack mounting bracket, a roof rack stanchion, a roof rack side rail, and a roof rack pad, such that it is possible to ensure structural durability further improved by a fastening force between an insert bolt and a bracket fixing bolt at the time of assembling the roof rack apparatus with a vehicle body. The roof rack mounting bracket is symmetric in a forward/rearward direction and a leftward/rightward direction with respect to a center of the insert bolt, such that the roof rack apparatus may be used in common. An operator may replace the roof rack with a new roof rack without detaching an interior material (head lining) in the vehicle, such that it is possible to prevent damage to the interior material at the time of replacing and repairing the roof rack.
