ABSTRACT:
An apparatus for constructing a roof on a structue using elongated roofing members, as well as the elongated roofing members. Elongated roofing members are produced, preferably near or on the structure, by continuously forming suitable male and female flanges on sheet metal material and periodically cutting the sheet metal material to predetermined lengths. The male and female flanges of adjacent elongated roofing members are interconnected by deflecting a portion of the female flange about the male flange to crimp the male flange between portions of the female flange. A plurality of clips having flanges may be interconnected with the structure, whereby the flanges are engagable, together with the male flanges, with the female flanges to provide for rapid simultaneous interconnection of both the female flange and the male flange with the structure.
