ABSTRACT:
A stair step assembly provides a safe means for mounting a peaked roof. Individual steps interlock with each other and with tiles of a tile roof so that the assembly cannot slide off the roof. Each step has a platform supported from below by a frame having a primary and secondary rest. The rests lie in contact with the roof and provide a foot constructed so that one portion of the foot is in contact with an vertical edge of a line of tiles to prevent the step from sliding.
