The roof truss members include a pivot end, a connection end, a roof facing edge, an inside edge, and a pivot surface. The roof base members include a receiving end, a connecting end, a top edge, a bottom edge, and a contact surface. The roof truss members are pivotally connected to the roof base members by a pivot fastener inserted through a pivot opening on the roof base members and a stator opening on the roof truss members. One or both of the roof truss members and the roof base members include an embedded portion extending from the roof facing edge or the bottom edge respectively into the central body. Expansion hole(s) are positioned along the embedded portion such that the polymer matrix expands through the expansion holes.
