A roof bar (10) for a motor vehicle (1) is disclosed in which an elongate load carrying member (13) is selectively held in a deployed position by a latch mechanism (20). A crossbar portion (15) of the elongate load carrying member (13) is wider than it is thick and is orientated such that the width of the crossbar portion (15) is vertically arranged when the roof bar (10) is in the deployed position so as to increase the resistance to vertical bending of the crossbar portion (15).
