ABSTRACT:
BACKGROUND
Federal and state regulations require roof safety systems to prevent workmen from falling from a roof during the construction or repair of the roof. These roof safety systems are necessary especially on commercial buildings that are normally more than one story above ground level. Most of the roof safety systems are not compatible for use on flat type roofs.
It is an object of the present invention to provide a roof safety system which provides protection to workmen on a roof, is inexpensive, easy to transport, and easy to install and remove.
It is another object of the present invention to provide a roof safety system for use on a flat type roof.

The present invention is a roof safety system utilizing a bracket which includes a first upright having a top and bottom. The bracket has a cross-member having a first and second end. The cross-member at its first end extends forward from the first upright near the top of the first upright. The bracket has a second upright attached to the second end of the cross-member. There is a roof attachment unit including a roof plate and an upright attachment plate. The roof plate extends forward from the first upright and the upright attachment plate extends downward along the first upright from the roof plate. The bracket includes a receiver box extending from the bottom of the first upright and a horizontal stabilizer. The horizontal stabilizer includes an adjustment bar and face plate, where the adjustment bar adjustably fits into the receiver box. A series of such brackets can be set on a roof with safety line between the brackets to aid in the prevention workmen from off a roof. The bracket is easy to transport, install and remove from a roof.
