Abstract: A roof batten integrally-formed of plastic with spaced, generally parallel upper and lower surfaces and a series of struts connecting the upper and lower surfaces, to form chambers permitting the fluid passage from the back edge to the front edge of the batten when it is affixed generally horizontally along a roof surface.

Abstract: A roof batten made of plastic which inhibits the pooling of water by permitting water that may accumulate beneath concrete roof tiles or other lug mounted tiles, to pass through the batten. The batten has spaced upper and lower skins of sheet plastic connected by a series of spaced struts disposed normal to the skins. The struts are preferably uniformly spaced apart. The battens will range in length from about eighteen inches to preferably three feet, but can be realistically used in lengths up to six feet. The plastic used permits the battens to be nailed, screwed, or stapled to the roof sheathing for use.
