In G-W-L, Inc. v. Robichaux, 643 S.W.2d 392 (Tex. 1982), the alleged defect in the buyers' new home was a sagging roof. The trial court rendered judgment for the buyers on jury findings that the builder "had failed to construct the roof in a good workmanlike manner and that the house was not merchantable at the time of completion." Robichaux, 643 S.W.2d at 392. The court of appeals affirmed. We disagreed and rendered judgment for the builder. Id. The Court held that the implied "warranty of merchantability" was a sales warranty under the Texas Uniform Commercial Code, which did not apply to the sale of a house. Id. at 394. Then, in reviewing the jury finding that the roof was not constructed in a good and workmanlike manner, the Court conflated the Humber warranties of good workmanship and habitability, referring to the warranty at issue as both the "implied warranty of fitness" and the "implied warranty of habitability." Id. at 393. In fact, the implied warranty of habitability was not at issue in the case because the jury had only found a breach of the implied warranty of good and workmanlike performance. See id. at 392. The Court nevertheless concluded that language in the sales documents that there were no "warranties, express or implied, in addition to said written instruments" was sufficiently clear to effectively disclaim the implied warranty of habitability. Id. at 393. The Court held that a purchaser of a new home can waive the implied warranties of good and workmanlike construction and habitability if the language waiving those warranties is clear and free from doubt. In Robichaux, the alleged defect in the buyers' new home was a sagging roof.

Id. at 393. In Robichaux, the Court failed to distinguish between habitability and good workmanship, conflating the two implied warranties and concluding that they could be disclaimed with clear language. Robichaux, 643 S.W.2d at 393.
