Abstract: An apparatus for retrofitting a metal roof includes a plurality of dual-tiered major ribs and a plurality of panel flats spaced therebetween, such that when installed over an existing metal roof containing overlapping R panels, the major ribs of the new roof panel are aligned with the major ribs of the underlying roof panel.

Abstract: A vented closure for installation in a roofing system between the upper end of a roofing panel and a ridge cap. The vented closure is die-pressed into a cap flange for attachment to the ridge cap; a downwardly disposed closure wall connected to the cap flange; a bottom wall connected to the closure wall; an upwardly disposed inner sidewall connected to the bottom wall; and a vent opening located in the closure wall. Either a screen or a multiplicity of louvers covers the vent opening. The present invention closes the spaces in the ends of the roofing panel and conforms to the profile of the panel in such a way as to prevent entry of water, debris and vermin but permit the passage of air.
