ABSTRACT:
A roofing system of the batten type using sheet steel components formed of elongated pan sections.
Each pan section has a wide flat elongated central region which lies flat on the roof and is centrally located between upstanding side walls running the full length of the central region. One side wall is formed of a single walled structure, while the other parallel side wall is formed of a partial rectangular inverted channel wherein the sheet metal is folded back on itself to provide a double wall thickness to the channel, and the marginal edge of the sheet metal is projected outwardly beyond the outermost wall of the double walled structure and in planar alignment with the central region of the pan section and adapted to be fastened to the roof by fasteners located at spaced intervals along its length. Each pan section is adapted to be longitudinally engaged with an adjacent pan section with the single walled structure side wall of one pan section engaging within the double walled structure side wall of the adjacent pan section, the central region of one pan section overlying the nailed down marginal edge of the adjacent pan section. The engaged side walls of adjacent pan sections form the batten-like portions of the covered roof and have great strength and rigidity to resist dislodgement of the roofing by wind force.
