Patent abstract

A safety assembly is provided for placement on a roof of a building, near an edge of the roof, having a ladder restraint, an upstanding barrier, and a counterweight. The ladder restraint has an opening to receive a ladder that provides access to the roof. The opening is sized to restrict left and right sideways movement of the ladder. The upstanding barrier extends on left and right sides of the ladder restraint to block falls by a user. The counterweight is interconnected to both the ladder restraint and the upstanding barrier, and is disposed to prevent forward tipping of the upstanding barrier by the user, and to prevent sideways tipping of the ladder during use, when the safety assembly is placed on the roof and the ladder is received through the ladder restraint. The safety assembly may be assembled on the roof without penetrating the roof's waterproofing membrane.
