  • Flat style roof drainage system and low point column head
    Patent number: 6185889
    Abstract: A flat roof drainage system is disclosed which utilizes a low point column head which allows the roof to be drained at the center of a structural member located at the low point of the roof. More specifically, the low point column head is a structural extension of a building column and is adapted to permit the attachment of support beams at the column head as well as the placement of a roof drain at the center of the column head so that the roof drain can be place directly at the lowest area of the roof to eliminate standing water.
