An adjustable bracket for a metal roof includes a bolt and a top platform with a hole sized to receive the bolt. The top platform provides a flat surface on which can be attached an L bracket. A left bracket has a curved portion with a slot for receiving the bolt. A right bracket has a curved portion with a slot for receiving the bolt. A bottom nut is sized to fit and secure the bolt. Once the top platform, the slot in the left bracket and the slot in the right bracket receive the bolt, the slot in left bracket and the slot in right bracket allow adjustment of an angle of attachment of the angle-adjustable bracket to the metal roof, until the bolt is tightened by the bottom nut.
