1. A roof batten comprising spaced, generally parallel upper and lower surfaces with a series of struts connecting the upper and lower surfaces, wherein the spaced surfaces are elongated having a front edge, a back edge and side ends peripheral to the surfaces, wherein the struts are spaced from one another, said struts and surfaces forming a series of chambers for fluid passage, wherein the upper and lower surfaces and the struts are formed having a thickness of at least 1/32 inch, wherein the struts and the upper and lower surfaces are integrally-formed of plastic, and wherein the spaced surfaces are separated by at least 5/16 inch. 2. The batten of claim 1, wherein the batten is capable of supporting 200 pounds of pressure over an area 3 inches in diameter with no noticeable effect. 3. The roof batten of claim 1, wherein the struts are spaced regularly. 4. The roof batten of claim 1, wherein when viewed in front profile the area of the upper and lower surfaces and struts occupies less than about 50% of the area of the chambers. 5. The roof batten of claim 4, wherein when viewed in front profile the area of the upper and lower surfaces and struts occupies less than about 40% of the area of the chambers. 6. The roof batten of claim 5, wherein when viewed in front profile the area of the upper and lower surfaces and struts occupies less than about 33% of the area of the chambers. 7. The roof batten of claim 1, wherein the plastic is susceptible of being affixed to a roof by any of nailing, stapling, or screwing means. 8. The roof batten of claim 1, wherein the plastic is polypropylene. 9. The roof batten of claim 1, wherein the batten has a recycled plastic content. 10. The roof batten of claim 1, wherein the spaced surfaces are separated by at least ½ inch. 11. The roof batten of claim 1, wherein the batten is at least 1¼ inches from the front edge to the back edge. 12. The roof batten of claim 1, wherein the batten is at least 2 inches from the front edge to the back edge. 13. The roof batten of claim 1, wherein the batten is at least 3 inches from the front edge to the back edge. 14. The roof batten of claim 1, having at least ⅜ inch between spaced struts. 15. The roof batten of claim 1, having at least ½ inch between spaced struts. 16. The roof batten of claim 1, wherein the chambers have an average cross-sectional profile having an area of at least 1 square centimeter. 17. The roof batten of claim 1, wherein the batten is at least 18 inches between the ends. 18. The roof batten of claim 1, wherein the batten is at least 36 inches between the ends. 19.
