Abstract: Disclosed is a panel for installation with similar adjacent top, bottom and side panels to form a roof having the appearance of a wooden shake roof. The panel has a generally rectangular panel body with an irregular surface of generally trapezoidal shake-like modules of different heights and widths, which surface is symmetrical only about the lateral center line of the panel. The modules at the ends of the panel body are configured to overlap with an end module of an adjacent side panel. The panel also features a nose flange extending downwardly from the front edge of the panel body which is irregularly configured so that the nose flange bottom edge is adapted to abut the panel body of an adjacent bottom panel. A rear upstand extends upwardly from the rear edge of the panel body and is irregularly configured so that the front surface of the rear upstand is adapted to mate with the nose flange rear surface of an adjacent top panel.
