An interlocking panel system for top-down or bottom-up installation on an underlying structure including a plurality of panels, with an uphill course and a downhill course where each panel is generally rectangular, having an uphill edge and opposing downhill edge. An interlocking member is disposed along the uphill edge, and a receiving member adapted to receive the interlocking member and a joining flange are disposed along the downhill edge. A first panel is positioned on an underlying structure. In top-down installation, a clip is disposed along the downhill edge of the first panel and affixed to the underlying structure, and a second panel is engaged with the receiving member of the first panel. In bottom-up installation, the first panel is affixed to the underlying structure, and a second panel is engaged with the interlocking member of the first panel, and then affixed to the underlying structure. |
