Abstract

A method and an apparatus for constructing a roof on a structure 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 engageable, 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.

Claims

1. An elongated roofing member for the construction of a roof for a structure, said elongated roofing member comprising:

(a) an elongated flat central portion;

(b) an elongated male flange extending from one edge of said elongated flat central portion, said elongated male flange comprising a first elongated portion extending angularly outwardly and upwardly from said elongated flat central portion and a second elongated portion extending angularly upwardly from said first elongated portion generally in the direction toward the area above said elongated flat central portion; and

(c) an elongated female flange extending from the opposite edge of said elongated flat central portion, said elongated female flange comprising a first elongated portion extending angularly outwardly and upwardly from said elongated flat central portion, a second elongated portion extending angularly upwardly from said first elongated portion generally in the direction toward the area above said elongated flat central portion, a third elongated portion extending angularly upwardly from said second elongated portion generally in the direction away from the area above said elongated flat central portion, and a fourth elongated portion extending angularly downwardly from said third elongated portion generally in the direction away from the area above said elongated flat central portion, said second, third and fourth elongated portions of said elongated female flange defining an elongated channel for receiving a second elongated portion of an elongated male flange of an adjacent elongated roofing member, said fourth elongated portion of said elongated female flange being deflectable such as to crimp the second elongated portion of the elongated male flange of the adjacent elongated roofing member between said third and fourth elongated portions of said elongated female flange to engage the elongated male flange of the adjacent elongated roofing member with said elongated female flange for interconnection of adjacent elongated roofing members.

2. The elongated roofing member of claim 1 further comprising at least one elongated rib formed along said elongated flat central portion to provide rigidity to said elongated roofing member.

4. The elongated roofing member of claim 1 wherein said elongated male flange further comprises a third elongated portion extending angularly downwardly from said second elongated portion of said elongated male flange generally in the direction away from the area above said elongated flat central portion.

3. An elongated roofing member for the construction of a roof for a structure, said elongated roofing member comprising:

(a) An elongated flat central portion;

(b) An elongated male flange extending from one edge of said elongated flat central portion, said elongated male flange comprising a first elongated portion extending angularly outwardly and upwardly from said elongated flat central portion at an angle of substantially 135 degrees relative to said elongated flat central portion and a second elongated portion extending angularly upwardly from said first elongated portion at an angle of substantially 90 degrees relative to said first elongated portion; and

(c) An elongated female flange extending from the opposite edge of said elongated flat central portion, said elongated female flange comprising a first elongated portion extending angularly outwardly and upwardly from said elongated flat central portion at an angle of substantially 135 degrees relative to said elongated flat central portion, a second elongated portion extending angularly upwardly from said first elongated portion at an angle of substantially 90 degrees relative to said first elongated portion, a third elongated portion extending angularly upwardly from said second elongated portion at an angle of substantially 90 degrees relative to said second elongated portion, and a fourth elongated portion extending angularly downwardly from said third elongated portion at an angle of substantially 90 degrees relative to said third elongated portion, said second, third and fourth elongated portions of said elongated female flange defining an elongated channel for receiving a second elongated portion of an elongated male flange of an adjacent elongated roofing member, said fourth elongated portion of said elongated female flange being deflectable such as to crimp the second elongated portion of the elongated male flange of the adjacent elongated roofing member between said third and fourth elongated portions of said elongated female flange to engage the elongated male flange of the adjacent elongated roofing member with said elongated female flange for interconnection of adjacent elongated roofing members.
