1. A method of applying an adhesive to a vehicle roof comprising:
providing a roof panel including a first side opposite a second side;
providing a roof stiffener including a first side opposite a second side, the roof stiffener including at least a first vacuum aperture and a second vacuum aperture each extending through the roof stiffener from the first side of the roof stiffener to the second side of the roof stiffener;
applying a first adhesive bead to the first side of the roof panel or the first side of the roof stiffener;
applying a second adhesive bead to the first side of the roof panel or the first side of the roof stiffener; and
positioning the first side of the roof panel facing the first side of the roof stiffener to define a chamber therebetween,
wherein the roof stiffener or the roof panel includes an outer perimeter that defines an opening to the chamber,
wherein the first adhesive bead and the second adhesive bead contact the roof panel and the roof stiffener, the first adhesive bead defines a first continuous perimeter around the first vacuum aperture, and the second adhesive bead defines a second continuous perimeter around the second vacuum aperture,
wherein the first adhesive bead includes an inner periphery and an outer periphery and the second adhesive bead includes an inner periphery and an outer periphery, and
wherein the outer periphery of the first adhesive bead and the outer periphery of the second adhesive bead are in fluid communication with the opening to the chamber.
