A fascia rail system includes: an angle profile component including a first upper support, a lower support, and a mount surface; a clamping profile component including a second upper support, a front face, and a groove between the second upper support and the front face; a panel inserted into the groove of the clamping profile component; and a cover overlying the angle profile component and the clamping profile component. The angle profile component is mountable to an edge of a flooring structure at the mount surface. The second upper support of the clamping profile component is attached to the first upper support of the angle profile component. Methods for installing a fascia rail system are also described.
