Claim:
A system, relating to improving in-service performance of at least one roof assembly utilizing at least one roof tile, said system comprising: a) at least one composite roof batten structured and arranged to support at least one roof tile over at least one roof structure; b) wherein said at least one composite roof batten comprises i) at least one substantially rigid low-density core of expanded foam material comprising an elongated bar having a longitudinal axis, an upper surface, a lower surface, and at least one channel formed in the lower surface of the elongated bar, the at least one channel being transverse to the longitudinal axis and forming contours in the lower surface; ii) at least one upper reinforcing layer overlaying said at least one substantially rigid low-density core, said at least one upper reinforcing layer structured and arranged to reinforce said upper surface of said at least one substantially rigid low-density core, and iii) at least one lower reinforcing layer underlaying said at least one substantially rigid low-density core, said at least one lower reinforcing layer structured and arranged to reinforce said lower surface of said at least one substantially rigid low-density core, said at least one lower reinforcing layer conforming to the lower surface and the contours formed therein by the at least one channel for providing at least one opening between the at least one composite roof batten and the at least one roof structure; and c) wherein said at least one upper reinforcing layer and said at least one lower reinforcing layer are firmly attached to said at least one substantially rigid low-density core.
