[1] Appellants argue that the trial court committed reversible error in granting Carlisle’s motion for summary judgment because genuine issues of material fact exist between the parties. More particularly, they first contend genuine issues of material fact exist as to Kidde’s allegations of negligence by Carlisle.
*67Summary judgment shall be rendered if “the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that any party is entitled to a judgment as a matter of law.” N.C.G.S. § 1A-1, Rule 56(c); see Johnson v. Insurance Co., 300 N.C. 247, 266 S.E. 2d 610 (1980). Once a party moving for summary judgment has made and supported his motion, the burden shifts to the non-movant to introduce evidence of specific facts showing there is a genuine issue for trial. Ward v. Durham Life Ins. Co., 90 N.C. App. 286, 368 S.E. 2d 391 (1988). The non-movant does not have to establish that he would prevail on the issue involved, he only has to show that the issue exists. Id.
Kidde and Gateway claim that Carlisle owes duties to both arising out of Carlisle’s design of the M.A.R.S. system (which duties they claim encompass the mechanics of fastening the membrane to the building as well as the layout and installation methods in application).
Actionable negligence presupposes the existence of a legal relationship between parties by which the injured party is owed a duty by the other, and such duty must be imposed by law .... The law imposes upon every person who enters upon an active course of conduct the positive duty to exercise ordinary care to protect others from harm. A duty of care may arisé out of a contractual relationship, the theory being that accompanying every contract is a common-law duty to perform with ordinary care the thing agreed to be done, and that a negligent performance constitutes a tort as well as a breach of contract.
Olympic Products v. Roof Systems, Inc., 88 N.C. App. 315, 322, 363 S.E. 2d 367, 371, disc. rev. denied, 321 N.C. 744, 366 S.E. 2d 862 (1988) (quotations and citations omitted).
Privity of contract is not required in order to recover against a person who negligently performs services for another and thus injures a third party. There is a duty to protect third parties where a reasonable person would recognize that if he does not use ordinary care and skill in his own conduct, he will cause damages or injury to the person or property of the other. See Davidson & Jones, Inc. v. County of New Hanover, 41 N.C. App. 661, 255 S.E. 2d 580, disc. rev. denied, 298 N.C. 295, 259 S.E. 2d 911 (1979).
*68In the case sub judice Carlisle owed a duty of care to Gateway through privity of contract. Carlisle owed a duty to Kidde because a reasonable person would have understood that if Carlisle did not use reasonable care in its conduct, it would cause injury to Kidde. See id.
Carlisle was granted summary judgment based upon the pleadings, affidavits and depositions which it claims show that it neither provided defective materials and design, nor was it negligent in providing instruction, training, and supervision of installation procedures by Gateway. James A. Moser, president of Gateway, however, stated through affidavit that the M.A.R.S. system was defective in design, and the methods used by Carlisle preclude the installation of a M.A.R.S. system roof in a workmanlike and watertight manner.
“If different material conclusions can be drawn from the evidence, then summary judgment should be denied.” Herbert v. Browning-Ferris Industries, 90 N.C. App. 339, 341, 368 S.E. 2d 416, 417 (1988). We hold that different material conclusions could be drawn from the evidence presented through affidavits by Gateway and Kidde. Moser, even though an agent of Gateway, had been in the roofing business for twenty years and stated that the M.A.R.S. system was defective. It is for a jury to determine whom to believe, Gateway and Kidde or Carlisle. Summary judgment is therefore inappropriate on the negligence claims against Carlisle.
[2] Appellants next argue that genuine issues of material fact exist as to Kidde’s allegations of breach of implied warranties. Carlisle maintains, inter alia, that it tendered an express warranty to Kidde which was rejected, and this rejection defeats any implied warranty claim.
N.C.G.S. § 25-2-314 provides in part:
(1) Unless excluded or modified (G.S. 25-2-316), a warranty that the goods shall be merchantable is implied in a contract for their sale if the seller is a merchant with respect to goods of that kind .... (2) Goods to be merchantable must be at least such as (a) pass without objection in the trade under the contract description ....
N.C.G.S. § 25-2-316 reads in pertinent part:
(2) Subject to subsection (3), to exclude or modify the implied warranty of merchantability or any part of it the *69language must mention merchantability and in case of a writing must be conspicuous, and to exclude or modify any implied warranty of fitness the exclusion must be by a writing and conspicuous. Language to exclude all implied warranties of fitness is sufficient if it states, for example, that “There are no warranties which extend beyond the description on the face hereof.”
(3) Notwithstanding subsection (2)
(a) unless the circumstances indicate otherwise, all implied warranties are excluded by expressions like “as is,” “with all faults” or other language which in common understanding calls the buyer’s attention to the exclusion of warranties and makes plain that there is no implied warranty; and
(b) when the buyer before entering into the contract has examined the goods or the sample or model as fully as he desired or has refused to examine the goods there is no implied warranty with regard to defects which an examination ought in the circumstances to have revealed to him; and
(c) an implied warranty can also be excluded or modified by course of dealing or course of performance or usage of trade.
Carlisle’s offer and Kidde’s rejection of a five-year express warranty of the roof installed for Kidde do not fall within the exclusion provisions of N.C.G.S. § 25-2-316. A five-year warranty would have far exceeded the protection offered by U.C.C. § 2-314, but the offer and rejection of it do not automatically waive the implied warranty. We conclude that there was an implied warranty of merchantability when Carlisle contracted with Gateway to provide a roofing system for Kidde. We also conclude that because of the affidavit of Moser, Gateway’s president, there is a genuine issue of material fact as to whether Carlisle breached the implied warranty. See Herbert, 90 N.C. App. 339, 368 S.E. 2d 416; see also Ward, 90 N.C. App. 286, 368 S.E. 2d 391.
[3] Carlisle contends that appellants’ claims of negligence and breach of implied warranty are insufficient as a matter of law and do not comply with Rule 8(a) of the North Carolina Rules of Civil Procedure.
Gateway’s third-party complaint and Kidde’s crossclaim against Carlisle were initiated in United States Bankruptcy Court. Gateway’s third-party complaint (and thus Kidde’s claim) was severed from *70the main action on the debt and remanded to the Guilford County Superior Court.
Rules 8(a) of Federal Rules of Civil Procedure and the North Carolina Rules of Civil Procedure differ in their requirements for pleadings. See Sutton v. Duke, 277 N.C. 94, 176 S.E. 2d 161 (1970). The Federal rule requires a pleading to contain only “a short and plain statement of the claim showing that the pleader is entitled to relief.” Fed. Rules of Civ. Proc. Rule 8(a); see id. The North Carolina rule requires “[A] short and plain statement of the claim sufficiently particular to give the court and the parties notice of the transactions, occurrences, or series of transactions or occurrences, intended to be proved showing that the pleader is entitled to relief.” N.C.G.S. 1A-1, Rule 8(a)(1). Merely asserting a grievance is not enough to comply with the North Carolina Rule 8(a). Sutton, 277 N.C. 94, 176 S.E. 2d 161.
The first avenue by which a party may properly address the failure to state a claim is through Rule 12(b)(6) of the North Carolina Rules of Civil Procedure. N.C.G.S. § 1A-1, Rule 12. A motion under Rule 12(b)(6), however, cannot be raised for the first time on appeal. Collyer v. Bell, 12 N.C. App. 653, 184 S.E. 2d 414 (1971).
The other way to address failure to properly state a claim is through Rule 12(e) of the North Carolina Rules of Civil Procedure. N.C.G.S. § 1A-1, Rule 12(e). Rule 12(e) is a way a party may move for a more definite statement of the claim before interposing his responsive pleading. Id. If a party pleads responsively without moving for a more definite statement, he waives his right to do so.
In the case sub judice, Carlisle neither made a motion under 12(b)(6), nor a motion under Rule 12(e). See N.C.G.S. 1A-1, Rule 12. It is therefore precluded from making these motions on appeal. See Collyer, 12 N.C. App. 653, 184 S.E. 2d 414; see id.
[4] Carlisle also contends that appellants’ claims fail under Chapter 99B, North Carolina’s Products Liability statute.
N.C.G.S. § 99B-3 reads in pertinent part:
(a) No manufacturer or seller of a product shall be held liable in any product liability action where a proximate cause of the personal injury, death or damage to property was either an alteration or modification of the product by a party other than the manufacturer or seller, which alteration or modifica*71tion occurred after the product left the control of such manufacturer or such seller ....
Subsection (b) provides that for the purpose of this section, alteration or modification “includes failure to observe routine care and maintenance.” Id.
Carlisle particularly argues that there was ample evidence of Kidde’s failure to observe routine care and maintenance of the roof. That may well be, but there is also evidence of record that the roof and design were defective. Appellants do not have to show that they will prevail at trial, they only have to show that there is a genuine issue of material fact. See Ward, 90 N.C. App. 286, 368 S.E. 2d 391 (1988).
Carlisle also argues that the roof was not properly installed by Gateway and thus under Chapter 99B-4 Carlisle is not liable. N.C.G.S. § 99B-4 reads in pertinent part:
No manufacturer or seller shall be held liable in any product liability action if:
(1) The use of the product giving rise to the product liability action was contrary to any express and adequate instructions or warnings delivered with, appearing on, or attached to the product or on its original container or wrapping, if the user knew or with the exercise of reasonable and diligent care should have known of such instructions or warnings ....
Carlisle would be able to use 99B-4 as a bar to appellants’ arguments had it not contracted to instruct Gateway on installation procedures, and had it not in fact assisted Gateway in the installation of the roof on the Kidde building. See id.
[5] Appellants lastly argue that genuine issues of material fact exist as to Kidde’s allegations of breach of express warranty. Car-lisle counters by arguing that it offered Kidde an express warranty which was rejected.
N.C.G.S. § 25-2-313 reads in pertinent part:
(1) Express warranties by the seller are created as follows:
(a) Any affirmation of fact or promise made by the seller to the buyer which relates to the goods and becomes part *72of the basis of the bargain creates an express warranty that the goods shall conform to the affirmation or promise.
(b) Any description of the goods which is made part of the basis of the bargain creates an express warranty that the goods shall conform to the description.
The critical inquiry here is whether the seller’s statements were regarded by the buyer as his reason for purchasing the goods. Pake v. Byrd, 55 N.C. App. 551, 286 S.E. 2d 588 (1982).
Rex Benchoff, architect and engineer for Grove, stated in his deposition that Grove relied upon information and technical assistance by Carlisle in choosing the M.A.R.S. roof design. Under N.C.G.S. § 25-2-313, Grove’s reliance would establish an express warranty by Carlisle. Summary judgment is not appropriate here, where there is evidence of such reliance.
Reversed.
Judges Johnson and Phillips concur.
