METAL ROOFING SYSTEM WITH HOOK-ENDED ROOFING SHEETS AND MATING HOLD-DOWNS
A roofing system features a plurality of roofing sheets each having an outer perimeter of which two opposing perimeter edges respectively define a fastening edge and a hooking edge. One or more fastening holes penetrate the sheet near the fastening edge. At the hooking edge, the sheet is bent under itself to form a hooking portion reaching back toward the fastening edge. A plurality of hold-downs are placed atop a first row of roofing sheets near the fastening edges thereof, and have apertures aligned with the fastening holes of the roofing sheets, through which the hold-downs are fastened to the a roof deck. The hooking edges of a next row of roofing sheets hook to the affixed hold-downs of the first row, thus coupling the two rows of sheets together and concealing the first row's fastened connection to the roof deck beneath the second row.
