An adjustable roof truss that includes roof truss members, roof base members and a central body containing a polymer matrix. 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.

What is claimed is: 1. An adjustable composite roof truss comprising: one or more roof truss members that include a pivot end, a connection end, a roof facing edge, an inside edge, and a pivot surface; one or more roof base members that include a receiving end, a connecting end, a top edge, a bottom edge, and a contact surface; and one or more central bodies, substantially parallelepipedic in shape, comprised of an expanded polymer matrix, having opposite faces, a first surface and an opposing second surface; wherein the roof truss members are pivotally connected to the roof base members by a pivot fastener inserted through a pivot opening positioned between a midpoint and the receiving end along the contact surface of the roof base members and a stator opening located between a midpoint and the pivot end of the roof truss members; wherein the roof base members include an embedded portion extending from the roof facing edge or the bottom edge respectively such that the embedded portion longitudinally extends across and into a central body; wherein the roof base members include an exposed portion longitudinally extending above the central body; and wherein one or more expansion holes are positioned along the embedded portion between the first surface and the second surface of the central body such that the polymer matrix expands through the expansion holes. 2. The adjustable composite roof truss according to claim 1, wherein the roof truss members and roof base members pivot from a parallel orientation to an orientation where the roof truss members form and angle relative to the bass members. 3. The adjustable composite roof truss according to claim 1, wherein the central body has a thickness measured as the distance between the first surface and the second surface of from 2 cm to 30.5 cm. 4. The adjustable composite roof truss according to claim 1, wherein the expanded polymer matrix comprises one or more polymers selected from the group consisting of homopolymers of vinyl aromatic monomers; copolymers of at least one vinyl aromatic monomer with one or more of divinylbenzene, conjugated dienes, alkyl methacrylates, alkyl acrylates, acrylonitrile, and/or maleic anhydride; polyolefins; polycarbonates; and combinations thereof. 5. The adjustable composite roof truss according to claim 1, wherein the expanded polymer matrix comprises carbon black, graphite or a combination thereof. 6. The adjustable composite roof truss according to claim 1, wherein the expanded polymer matrix comprises an interpolymer of a polyolefin and in situ polymerized vinyl aromatic monomers. 7. The adjustable composite roof truss according to claim 1, wherein the roof truss members and/or the roof base members comprise a material selected from the group consisting of metal, construction grade plastics, composite materials, ceramics, and the like. 8. The adjustable composite roof truss according to claim 1, wherein the roof truss members and/or the roof base members comprise a metal selected from the group consisting of aluminum, steel, stainless steel, tungsten, molybdenum, iron and alloys and combinations of such metals. 9. The adjustable composite roof truss according to claim 1, wherein one or more surfaces of the roof truss members and/or the roof base members have a texturized surface. 10. The adjustable composite roof truss according to claim 1, wherein the embedded portion of the roof base members extends through the first surface and terminates at least 1 cm from the second surface of the central body. 11. The adjustable composite roof truss according to claim 1, wherein the embedded portion of the roof base members extends through the first surface and terminates substantially flush with the second surface of the central body. 12. The adjustable composite roof truss according to claim 1, wherein the roof base members further comprise one or more support openings along the pivot surface and/or contact surface respectively. 13. The adjustable composite roof truss according to claim 12, wherein the support openings are adapted to receive a connecting bar extending from a first roof truss member or a first roof base member to a second roof truss member or a second roof base member respectively. 14. The adjustable composite roof truss according to claim 13, wherein the connecting bar has a cross-sectional shape that includes a web, a top flat portion extending perpendicularly from a first edge of said web, a first bottom portion extending from a second edge of said web, and a second bottom portion extending from an end of the first bottom portion. 15. The adjustable composite roof truss according to claim 12, wherein the support openings are adapted to receive utility lines. 16. The adjustable composite roof truss according to claim 15, wherein the utility lines are one or more selected from the group consisting of water lines, waste lines, chases, telephone lines, cable television lines, antenna lines, electrical lines, ductwork, and gas lines. 17. The adjustable composite roof truss according to claim 1, wherein the expansion holes have a cross-sectional shape selected from the group consisting of round, oval, elliptical, square, rectangular, rounded rectangular, triangular, hexagonal, parallelogram, oblong, octagonal and combinations thereof. 18. A building comprising two or more of the adjustable composite roof trusses according to claim 1.
