1. A method of making a panel configured for attachment to a mounting surface of a building structure, the method comprising:
molding a polymer in a mold cavity of a continuous mold formed at least in part by opposing surfaces of two opposed belts;
wherein the panel extends lengthwise along a longitudinal axis and comprises:
a top edge surface and a bottom edge surface spaced from each other and offset from the longitudinal axis; and
an inner surface and an outer surface opposed to each other;
wherein the inner surface comprises:
a contact portion disposed on a first reference plane;
a contour portion contoured toward the outer surface, away from the first reference plane, such that the contour portion defines a first channel and a second channel each extending lengthwise along at least a portion of the panel, the first channel being separated from the second channel by a wall having a plurality of curves, each curve permitting fluid communication between the first channel and the second channel; and
a lip adjacent the bottom edge surface, the lip disposed on a second reference plane offset from the first reference plane;
wherein the lip is configured to receive an outer surface of a top edge of an adjacent panel; and
wherein at least one of the two opposed belts comprises:
a contact portion-forming section; and
a contour portion-forming section; and
wherein the inner surface defines a flow path including a plurality of voids configured to guide flow of a fluid between the panel and the building structure, the plurality of voids including the first channel, the second channel, and the plurality of curves of the contour portion.
