The metal panels are installed on the top of the new roof. This is done by installing a series of metal clips along the roof's perimeter, then attaching each panel to these clips by attaching panels to each other and to the lumber strapping with special roofing screws with EPDM washer that seals the gap between the screws and the roofing panels . Once the panels have been attached, they are covered in felt paper, and shingles are applied over them.(no sense, remove it)
