A prefabricated roofing panel has two opposite parallel edges bevelled at an angle to the top and bottom flat surfaces, and a portion of each bevelled edge is blunt cut adjacent one of the flat surfaces to enable interlocking of the panels. Each panel has a sidelap on one side extending across a bevelled edge, and a headlap at one end. The panels are installed with adjacent bevelled edges in interlocking engagement.
