A roof frame configured to support a roof panel (108, 109), the roof frame comprising: a pair of longitudinal side portions, each of the longitudinal side portions comprising a first structure disposed on opposite sides of an aperture, the aperture configured to receive at least a portion of the roof panel (108, 109); a first lateral end portion configured to be coupled between each of the longitudinal side portions, the first lateral end portion comprising a second structure disposed adjacent the aperture at a first end of the longitudinal side portions; a second lateral end portion configured to be coupled between each of the longitudinal side portions, the second lateral end portion comprising a third structure disposed adjacent the aperture at a second end of the longitudinal side portions, opposite the first end; and a crossbeam comprising a fourth structure, the crossbeam disposed between the first lateral end portion and the second lateral end portion and configured to extend between the longitudinal side portions across at least a portion of the aperture, characterized in that at least one of the first, second, third, and fourth structures comprises a first surface formed from a first continuous fiber composite comprising a multidirectional laminate, wherein at least one of the first, second, third, and fourth structures comprises a second surface formed from a second continuous fiber composite comprising a unidirectional laminate, wherein the first surface and the second surface are selected to be formed from the first continuous fiber composite and the second continuous fiber composite, respectively, based at least upon a stress analysis for the respective surface, wherein the first surface exhibits a higher stress profile as compared to the second surface, and wherein the roof frame is overmolded using a two-step overmolding process comprising: forming the pair of longitudinal side portions, the first lateral end portion, and the second lateral end portion by: disposing a plurality of pieces of the first or second continuous fiber composite in an injection molding machine; and overmolding the plurality of pieces of the first or second continuous fiber composite with a polymeric resin to couple the plurality of pieces in the injection molding machine; independently forming the crossbeam; and attaching the crossbeam to the pair of longitudinal side portions. a pair of longitudinal side portions, each of the longitudinal side portions comprising a first structure disposed on opposite sides of an aperture, the aperture configured to receive at least a portion of the roof panel (108, 109);
