Generally, A roaring noise during belt rotation (without the A/C on) will often be caused by an idler pulley bearing going bad. There are occasions where Alternator bearings will also create a roaring noise during belt rotation. In-order to diagnose either of these problems simply remove the belt and rotate each of the pulleys by hand. The pulley failure will make itself apparent by noting that the noise begins when rotating the faulty pulley.
