Apparatus and method for retrofitting a metal roof

摘要

A method for retrofitting a metal roof formed of overlapping R panels having major ribs and panel flats spaced therebetween includes the steps of removing fasteners disposed along the overlapping margins of adjacent R panels; plugging the holes formed when the fasteners are removed from the R panels; positioning a RETRO R panel having dual-tiered major ribs and panel flats spaced therebetween over the metal roof; aligning the major ribs of the RETRO R panel with major ribs of the underlying R panel; and fastening the major ribs of the RETRO R panel to the major ribs of the underlying R panel. 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, the major ribs of the new roof panel are aligned with the major ribs of the underlying roof panel.
