Roofing structure includes roofing brackets having a first leg attached to vertical members of a roof structure and a second leg that extends at an angle from the first leg and attached to horizontal members of the roof structure. Brackets serve to attache the vertical members to a support surface of the roof. The first and second legs include a plurality of preformed patterned holes and slots having varying sizes to receive fasteners. The pattern and size of the holes and slots allows for fastening of the brackets to steel bar joists while enabling the fasteners in the slots to be fastened near center lines of the respective bar joists. The slot sizes and positions enable fastening to steel bar joists for most distances between the flanges of their top angle chord members.
