A composite wood panel is disclosed, the wood panel having parallel first and second longitudinal edges, and parallel upper and lower faces, and comprising: a groove formed along the second longitudinal edge, a complementary shaped tongue formed along the first longitudinal edge, and a barrier layer. A first surface extends from the tongue to the upper surface and forms a generally obtuse angle, α, with the upper surface, while a matching surface extends from the groove forming a generally acute angle, β, with the upper surface, and the sum of α and β is from about 175° to less than about 180°. The composite wood panel allows for convenient and fast assembly, particularly in constructing roofs, and also provides resistance against the penetration of water through the structure formed by the panels.

1. A composite wood panel having parallel first and second longitudinal edges, and parallel upper and lower faces, and comprising: a barrier layer made from fibers impregnated with a sizing compound, a groove formed along the second longitudinal edge, and a complementary shaped tongue formed along the first longitudinal edge; wherein a first surface extends from the tongue to the upper surface and forms a generally obtuse angle, α, with the upper surface, a matching surface extends from the groove forming a generally acute angle, β, with the upper surface, and the sum of α and β is from about 175° to about 185°. 2. The composite wood panel according to claim 1, wherein the fibers are cellulosic fibers. 3. The composite wood panel according to claim 1, wherein the sizing compound is selected from the group consisting of asphalt and non-asphaltic sizing. 4. The composite wood panel according to claim 1, wherein the barrier layer is selected from the group consisting of asphalt-impregnated felt and high density overlay. 5. The composite wood panel according to claim 1, wherein the panel further comprises a radiant barrier material. 6. The composite wood panel according to claim 5, wherein the radiant barrier material comprises a first layer of metal foil, and a backing layer. 7. The composite wood panel according to claim 5, wherein the radiant barrier material is attached to the parallel upper and lower faces. 8. The composite wood panel according to the claim 1, wherein the tongue has beveled edges. 9. The composite wood panel according to claim 1, wherein a first abutment is formed along the first longitudinal edge and extends from the tongue to the lower face and a second abutment is formed along the second longitudinal edge and extends from the groove to the lower face. 10. The composite wood panel according to claim 9, wherein the of the tongue is than the length of the groove so that the first abutment contacts the second abutment to form a tight fit. 11. The composite wood panel according to claim 1, wherein the width of the tongue is less than the width of the groove. 12. The composite wood panel according to claim 1, wherein the fibers are selected from the group consisting of cellulosic fibers, fiberglass fibers, polymer fibers, and glass fibers. 13. The composite wood panel according to claim 1, wherein the tongue continues uninterrupted along the length of the first longitudinal edge. 14. The composite wood panel according to claim 1, wherein the composite wood panel is composed of oriented strand board. 15. The composite wood panel according to claim 1, wherein the sum of α and β is about 180°. 16. A composite wood panel having parallel first and second longitudinal edges, and parallel upper and lower faces, and comprising: a groove formed along the second longitudinal edge, a complementary shaped tongue formed along the first longitudinal edge, and; wherein a first surface extends from the tongue to the upper surface and forms a generally obtuse angle, α, with the upper surface, a matching surface extends from the groove forming a generally acute angle, β, with the upper surface, and the sum of α and β is from about 175° to less than about 180°; and the first longitudinal edge and the second longitudinal edge abut below the tongue to create a tight joint fit. 17. A roof construction for a building comprising:a frame structure; anda plurality of composite wood panels attached to the frame structure, each panel having parallel first and second longitudinal edges, and parallel upper and lower faces, and comprising; a groove formed along the second longitudinal edge, a complementary shaped tongue formed along the first longitudinal edge, each cancel further comprising a barrier layer made from cellulosic fibers impregnated with a sizing compound anda first surface extends from the tongue to the upper surface and forms a generally obtu se angle, α, with the upper surface, a matching surface extends from the groove forming a generally acute angle, β, with the upper surface, and the sum of α and β is from about 175° to less than about 180°; whereinthe first angled surface, the second angled surface, and the top surface of the tongue define an upper space that forms an acute angle, θ, with the upper face of each panel. 18. A roof construction according to claim 17, wherein each panel further comprises a barrier layer.
