An improved roof panel system used on a building that exhibits, upon seaming, a substantially even distribution on both sides of such a seam is provided. Such a system thus permits not only increased resistance to wind uplift forces but also a more reliable roof in terms of load-bearing and load-carrying than typical single seamed roof panel systems. Particularly, the novel roof panel includes a female flange end portion with an extended T shape within its periphery and a male flange end portion with its own complementary T configuration to fit within the female flange. Such an extended T shape within the female flange end portion includes an extra extension that permits, upon engagement with the male flange end portion, two seams on either side of the engagement line of the two end portions of the roof panels. In such a manner, the two seams can also be compressed to become parallel with engagement line, or substantially perpendicular to the longitudinal axis of the roof line itself. A method of constructing a roof with such a roof panel system, as well as the individual roof panels themselves, and the finished roof exhibiting such a roof panel system are all encompassed within this invention. |
