Claim Text:
1. An interlocking panel system for top-down installation on an underlying structure, comprising: a plurality of panels defining an uphill course of panels and a downhill course of panels; wherein each of the panels includes a generally rectangular panel body with an uphill edge and an opposing downhill edge; an angled head disposed along the uphill edge of each panel body and a receiving member disposed along the downhill edge of each panel body, wherein the receiving member of the uphill course of panels is adapted to receive the angled head of the downhill course of panels, and wherein the receiving member has a span which permits positional adjustment of the downhill course of panels within predetermined lateral and rotational ranges defined within a plane substantially parallel with the underlying structure while the angled head is resiliently received within the receiving member, wherein the angled head includes a flange which extends from the uphill edge of the panel body at an angle of less than 90 degrees from the panel body, and wherein a height that the flange extends from the panel body is greater than a difference in length between the back wall and the downwardly depending wall, and wherein the uphill edge includes a bevel proximate the flange; and a joining flange disposed along a length of the receiving member for affixing the panel to the underlying structure, wherein the joining flange is disposed between the underlying structure and the downhill course of panels upon installation.
