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. The area of each outer skin section lying inside the perimeter of each grid section is free to expand or contract in response to temperature changes without causing relative movement of the watertight seal formed along the perimeter of each grid section.
