The present invention is an integrated housing mounting system for mounting ornamentation to buildings. Mount components are attached to a building in place of J-channel, J molding, drip edge, gutter apron or siding. Rail components are assembled to the desired length using connector components and lights or signage are attached to a rail component using hooks. A guide member is placed at each end of the assembled rail and the rail is guided through an opening in the mount component securing the lights or signage to the building. The rail components are then guided through an opening in the mount component.
