A roof structure for a vehicle can include a tailor-welded-blank, inner roof frame. The inner roof frame can include, at least in part, an elongated, transversely extending, intermediate roof rail having a first material thickness, and a plurality of reinforced roof rails. Each of the reinforced roof rails can extend away from the intermediate roof rail in a common direction toward a remote end of the inner roof frame. Each of the reinforced roof rails can have a different material thickness than the first material thickness of the intermediate roof rail.
