Roof batten

Abstract

A roof batten for use in spacing tiles or similar exterior roofing members from a roof overlayment is provided. In one embodiment, the batten includes at least one layer of a corrugated plastic material with a pair of generally planar plies and a convoluted ply cooperating with the planar plies to define a multiplicity of passages. The passages allow drainage of water infiltrating the tiles and further promote drying.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This application claims priority under 35 U.S.C. §119(e) to, and hereby incorporates by reference, U.S. Provisional Application No. 60 / 112,597, filed Dec. 17, 1998.FIELD OF THE INVENTION[0002]This invention relates to roof coverings and, in particular, this invention relates to building materials or devices which extend the lives of tile roofs by preventing water infiltration.BACKGROUND OF THE INVENTION[0003]Most tile roofs include an exterior decking or sheathing, which overlays a structural framework of either trusses or rafters. Typically, decking includes plywood sheets or other planking members. One or more layers of overlayment, such as felt (tar) paper, is usually attached to the decking. Battens are normally placed over the felt paper before tiles are installed. The battens are usually fixed to the roof by fasteners, such as nails or staples, driven through the battens and felt paper and into the roof decking. Battens are typical...

AI Technical Summary

Benefits of technology

[0007]This invention substantially meets the aforementioned needs. There is provided a spacer operatively disposable between a roof decking and an exterior roofing material. The spacer may include at least one layer of a material, the material defining a multiplicity of passages therethrough. The passages defined may extend generally transversely to a longitudinal axis of the spacer and may allow infiltrated liquids to drain therethrough, thereby preventing accumulation of the infiltrated liquids. The spacer may further include a generally planar first ply and a con

Problems solved by technology

If water is otherwise allowed to stand or pool, the water may infiltrate through the felt paper and penetrate the roof decking, thereby potentially causing deterioration of the roof decking and the underlying framework.

When horizontal batting is installed, water which has infiltrated the roof tiles tends to pool on the upper-slope sides of the batte
