Abstract: A multiple panel metal roofing system is installed on a continuous roof deck. Elongated support members are aligned to create a supporting frame structure formed as a plurality of grid sections each having sides defining the perimeter of each grid section. A plurality of substantially planar outer skin sections are aligned with the grid sections such that the edges of adjacent skin sections overlap above the upper surface of the support members. A layer of sealant is positioned between the overlapping edges of adjacent skin sections. Fasteners such as screws penetrate through the overlapping edges of adjacent skin sections and the intervening layer of sealant and extend into the upper surface of the underlying support members to immovably secure the overlapping edges of adjacent skin sections to the underlying support members and to form a compressed watertight seal along the perimeter of each grid section.

Abstract: A rectangular grid of support members is secured to a continuous load bearing roof deck. The interior of each grid section is filled with a layer of insulation extending from the roof deck to the top of the support members defining the grid. A plurality of flexible metal panels are positioned above each roof grid section to form overlapping joints between each of the panels. A strip of sealant is positioned within each of the overlapping joints. The overlapping joints are sequentially compressed. Compressive securing means are passed through each of the overlapping joints and secured to the upper surface of underlying support members at closely spaced apart intervals to interlock the adjacent panels and to form a compressed, water impervious seal along each of the overlapping joints.
