Roof clamps and methods of securing roof clamps are provided. The roof clamps include a saddle, a wedge, and a securing member. The securing member facilitates engaging a seam of a roof with the clamp and removably fixing the roof clamp to the seam through the camming action of the wedge against a region of the saddle. The securing member also serves as the connection point for an auxiliary item, such as a solar panel or a snow guard. The placement of the securing member allows the roof clamp to be secured from, and the auxiliary item to be attached at, a top surface of the saddle.
