OPINION AND ORDER
THOMAS W. THRASH, Jr., District Judge.
This is a multi-district class action arising out of the marketing and sale of allegedly defective roofing shingles. It is before the Court on the Plaintiffs Diane Dishman, Rodney Dishman, and Anthony Costanzo's Motion for Class Certification [Doc. 57]. For the reasons set forth below, the Plaintiffs' Motion for Class Certification [Doc. 57] is DENIED.
The Plaintiffs and putative class members are purchasers of Atlas Chalet and Stratford Shingles ("Shingles").1 The Defendant Atlas Roofing Corporation ("Atlas") designed, manufactured, and sold the Shingles.2 Atlas represented and continues to represent that the Shingles are durable, reliable, free from defects, and compliant with industry standards and building codes.3 The Plaintiffs allege that the Shingles were defective at the time of sale due to a flaw in the manufacturing process.4 Specifically, the manufacturing process "permits moisture to intrude into the Shingles, creating a gas bubble that expands when the Shingles are exposed to the sun resulting in cracking, blistering and premature deterioration of the Shingles."5 This premature deterioration supposedly leads to damage to other components of the house or building, including the interior.6 The Plaintiffs further allege that despite Atlas's knowledge of the defect, Atlas did nothing to correct the defective design and continued to market and warrant the Shingles as durable.7
Atlas provided four different limited warranties throughout the eleven-year class period.8 The initial limited warranty was a twenty-five-year warranty, and it provided that the Shingles were "free from manufacturing defects, which would reduce the useful life of the product."9 The warranty was transferrable to future property owners.10 On January 1, 2002, Atlas began issuing thirty-year limited warranties.11 The thirty-year warranty provided that the Shingles were "free from manufacturing defects, which results in leaks."12 Atlas also limited the number of transfers of the warranty. For the thirty-year warranty, the coverage could only be transferred once and the second owner had to provide Atlas notice of the transfer of coverage.13
The named Plaintiffs Diane and Rodney Dishman, who are residents of Dallas, Georgia, purchased their Chalet Shingles in 2010.14 Three years later, they noticed that their Shingles were suffering from blistering and granule loss and filed a warranty claim with Atlas.15 Atlas denied the claim, stating that the blistering was cosmetic and not the result of a manufacturing defect.16 The other named Plaintiff Anthony Costanzo, who is a resident of Douglasville, Georgia, had Chalet Shingles installed on his original construction home.17 In 2010, the Plaintiff discovered a water leak in his home, which he states was caused by blistering, cracking, and granule loss on his Shingles.18 Like the Dishmans, he filed a warranty claim with Atlas, but his claim was denied.19
On July 1, 2013, the named Plaintiffs filed suit on behalf of themselves and others similarly situated in the state of Georgia.20 They seek to bring their suit as a class action. Because similar consumer class actions were filed in five other states, the Judicial Panel on Multidistrict Litigation transferred all related class actions pending in federal court to this Court for coordinated or consolidated pretrial proceedings.21 After the Motion to Dismiss stage, the Plaintiffs' remaining claims in this class action are for Breach of Express Warranty (Count I), Breach of Implied Warranty of Merchantability (Count II), and Fraudulent Concealment (Count VI).22 As damages, the Plaintiffs seek the cost of replacing the Shingles. They propose two methods for calculating the replacement costs. First, they state that a common formula that calculates replacement costs on a square foot basis could be employed, allowing class members to recover by merely showing the size of their roofs.23 This method accounts for "each class member's damages are the expense of removing and discarding the defective shingles, including the cost of the replacement shingles plus all associated labor costs."24 In the alternative, they propose that individual class members can prove their actual replacement costs through a claims process.25
II. Class Certification Standard
To maintain a case as a class action, the party seeking class certification must satisfy each of the prerequisites of Rule 23(a) and at least one of the provisions of Rule 23(b).26 Rule 23(a) sets forth the four prerequisites to maintain any claim as a class action:
One or more members of a class may sue or be sued as representative parties on behalf of all members only if: (1) the class is so numerous that joinder of all members is impracticable; (2) there are questions of law or fact common to the class; (3) the claims or defenses of the representative parties are typical of the claims or defenses of the class; and (4) the representative parties will fairly and adequately protect the interests of the class.27
These prerequisites are commonly referred to as: (1) numerosity, (2) commonality, (3) typicality, and (4) adequacy of representation.28 Failure to establish any one of the four factors precludes certification. In addition, under Rule 23(b), the individual plaintiffs must convince the Court that: (1) prosecuting separate actions by or against individual members of the class would create a risk of prejudice to the party opposing the class or to those members of the class not parties to the subject litigation; (2) the party opposing the class has refused to act on grounds that apply generally to the class, necessitating final injunctive or declaratory relief; or (3) questions of law or fact common to the members of the class predominate over any questions affecting only individual members and that a class action is superior to other available methods for fair and efficient adjudication of the controversy.29 The party seeking class certification bears the burden of proving that these requirements are satisfied.30
The decision to grant or deny class certification lies within the sound discretion of the district court.31 When considering the propriety of class certification, the Court should not conduct a detailed evaluation of the merits of the suit.32 Nevertheless, the Court must perform a "rigorous analysis" of the particular facts and arguments asserted in support of class certification.33 Frequently, that "rigorous analysis" will entail some overlap with the merits of the plaintiff's underlying claim.34
A. Daubert Motions
In support of their Class Certification Motion, the Plaintiffs rely on the expert testimony of Dean Rutila and Anthony Mattina. The Defendant has filed Daubert motions challenging the admissibility of both Rutila's and Mattina's opinions. "Because this expert testimony is both challenged and critical to class certification, the Court cannot grant certification without first engaging in the analysis required by Federal Rule of Evidence 702 and Daubert v. Merrell Dow Pharmaceuticals, Inc."35
Federal Rule of Evidence 702 governs the admission of expert opinion testimony. Pursuant to that rule, before admitting expert testimony a court must consider: (1) whether the expert is competent to testify regarding the matters he intends to address; (2) whether the methodology used to reach his conclusions is sufficiently reliable; and (3) whether the testimony is relevant, in that it assists the jury to understand the evidence or determine a fact in issue.36 In ruling on the admissibility of expert testimony, "[t]he focus must be `solely' on the expert's `principles and methodology, not on the conclusions that they generate.'"37 If the expert predicates his testimony on an assumption that is belied by the evidence, the expert's testimony is properly excluded.38 The party offering the expert's testimony has the burden to prove it is admissible by a preponderance of the evidence.39
1. Dean Rutila
The Court finds that Mr. Rutila is qualified to render an expert opinion regarding the alleged premature failure of the Shingles. Rutila is a civil engineer and senior principal at Simpson Gumpertz & Heger ("SGH").40 He has an undergraduate and graduate degree in civil engineering from the University of Michigan and is a licensed professional civil engineer.41 Moreover, he has over thirty years of experience in the construction of buildings, including the investigation and repair of deteriorated roofing.42 At SGH, he has supervised many investigations into building failures.43
The Defendant first seeks to exclude Rutila's opinion that all Chalet/Stratford Shingles have effectively failed. Specifically, the Defendant argues that his testimony as to "effective failure" or "premature failure" will be unhelpful and confusing to the trier of fact, because "merely predicting that all the shingles will one day fail at some unknown time in the future does not answer any potentially relevant questions or disputed issues."44 Whether Rutila's opinion regarding premature failure assists the trier of fact depends on its relevancy. "Expert testimony which does not relate to any issue in the case is not relevant and, ergo, non-helpful."45 "In addition to being relevant, expert testimony should concern `matters that are beyond the understanding of the average lay person.'"46 "Proffered expert testimony generally will not help the trier of fact when it offers nothing more than what lawyers for the parties can argue in closing arguments."47
Here, Rutila tenders several opinions in support of his ultimate conclusion that the Shingles have prematurely failed. One such opinion is that the Shingles should have a service life of twenty-five to thirty years.48 This opinion is based on an industry standard — ASTM D3462 — and SGH's experience testing other shingles that meet the standard.49 Thus, when stating that the Shingles have prematurely failed, Rutila opines that the Shingles cannot be expected to fulfill their service life.50 This opinion is central to the Plaintiffs' contention that the Shingles need to be replaced and helps resolve an important, disputed issue: the Shingles' durability. Whether a shingle is durable is not something a reasonable lay person not versed in roofing and building standards could easily resolve.51 Thus, the Court rejects the Defendant's Motion in this regard.
The Defendant next contends that Rutila's opinions are based on an unreliable methodology. "To aid trial courts in assessing the reliability of a proposed expert's methodology, Daubert sets forth several non-exclusive factors that must be considered."52 The factors include: "(1) whether the expert's theory can be or has been tested; (2) whether the theory has been subjected to peer review and publication; (3) the known or potential rate of error of the particular scientific technique; and (4) whether the technique is generally accepted in the scientific community."53 These factors apply to scientific knowledge as well as technical knowledge, like engineering.54 But "flexibility is essential in assessing the reliability of expert testimony, and, as such `the law grants a district court the same broad latitude when it decides how to determine reliability as it enjoys in respect to its ultimate reliability determination.'"55
"[U]nlike the fields of `laboratory or medical testing, which employ rigorous and replicable protocols, technical fields such as engineering often involve more idiosyncratic methods of design and testing.'"56 "As a result, it is not unusual for a technical expert, such as an engineer, to state that his opinions are not based upon any specific method, but are based solely upon his general experience and knowledge after a review of the evidence."57 However, "engineers routinely rely upon established principles of physics, material sciences, and industrial design and often utilize technologically sophisticated and carefully calibrated testing methods and devices when arriving at their conclusions."58 Thus, "the accepted methodology, characterizing the practice of an expert in the field of engineering, simply does not involve guess work or even conjecture; rather, accepted methodology more often involves some inquiry into industry standards, practices, or publications and results in conclusions based upon concrete data, testing, measurements, or calculations."59
Before turning to Atlas's specific objections regarding reliability, it is worth clarifying the nature of Rutila's methodology. Rutila followed a qualitative sampling method.60 As described in an article from the Journal of ASTM International, the key principal of qualitative sampling "is that resulting causal findings and theoretical statements clearly must be emergent from and grounded in purposive (or judgmental) field observation. In other words the expert's step-by-step process of qualitative analysis builds toward general patterns that emerge from a series of purposeful collected databases . . . ."61 In accordance with this methodology, Rutila and his SGH team inspected 351 roofs with Stratford/Chalet Shingles.62 They then took 246 roofing samples and tested them.63 Of the samples, they performed extractions on forty-five of them and tear tests on sixteen of them.64 The extractions and tear tests were performed in accordance with ASTM D228 and ASTM D1922, respectively.65 Moreover, thirty-three samples were water jet cut and viewed under a microscope.66 Rutila also reviewed relevant industry literature, applicable industry standards, an Atlas manufacturing plant, and internal documents from Atlas.67 Based on his investigation, he determined that the blistering, cracking, and granule loss observed at the 351 roofs examined "is such that the shingles cannot reasonably be expected to resist ordinary weather events today."68 He stated that on all the roofs they examined, at least 10% of the Shingles had blisters, granule loss, and/or cracking, which he claims demonstrates the roofs need to be replaced.69 He further concluded that the excessive blistering was likely caused by moisture in the manufacturing process, and that there was likely a connection between the excessive granule loss and the moisture.70 For the excessive cracking, he opined that it was a result of the overlay pad thickness, the position of the fiberglass mat, and the modified asphalt overlay.71
Atlas responds by first arguing that because Rutila cannot predict the timing of all future actual failures, he "lacks a scientifically reliable basis to predict that any and all such failures will be premature if and when they occur."72 But as the Plaintiffs correctly point out, Rutila is not attempting to predict exactly when all the Shingles will actually fail. Rather, he states that — in their current condition — the Shingles will not withstand foreseeable weather events and thus have prematurely failed. The Defendant then argues that Rutila's estimation that the Shingles should last twenty-five to thirty years is not objectively verifiable or a generally accepted benchmark for comparable shingles. It points to SGH's "survey of roofers who estimated as little as 11 years as an average duration for properly designed (`not defective') 3 tab strip shingles."73 But this survey is not a scientific analysis. It is merely a compilation of opinions from members of the National Roofing Contractors Association and Roof Consultants Institute.74 Moreover, the eleven year estimate was only the minimum expected life; eighteen years was the mean expected life.75 Thus, while the survey may be helpful to the Defendant, it does not make Rutila's opinion unreliable. If the Defendant wishes to undermine Rutila's opinion regarding the expected life span of the Shingles, it may do so through cross-examination.76
Finally, the Defendant argues that Rutila's opinion regarding causation is unreliable, because he cannot rule out that the Shingles may actually fail for a variety of alternative reasons, like weather damage or ventilation. But Rutila did not attempt to predict what would cause the actual failure of the Shingles. Rather, Rutila addressed other possible causes for the Shingles' effective failure. In his expert report and deposition, he discredited possible alternative explanations for the Shingles' deterioration, including issues like installation, ventilation, and site conditions, such as sun exposure.77 Thus, like the previous opinion, the Defendant may attack Rutila's conclusion regarding causation on cross-examination. The Court rejects the Defendant's Daubert Motion to exclude Rutila's testimony.
2. Anthony Mattina
Atlas contends that neither Mattina's qualifications nor his methodology can support his proffered opinions. "[E]xperts may be qualified in various ways. While scientific training or education may provide possible means to qualify, experience in a field may offer another path to expert status."78 However, "the unremarkable observation that an expert may be qualified by experience does not mean that experience, standing alone, is a sufficient foundation rendering reliable any conceivable opinion the expert may express."79 As the Committee Note to the 2000 Amendments of Rule 702 expressly states, "[i]f the witness is relying solely or primarily on experience, then the witness must explain how that experience leads to the conclusion reached, why that experience is a sufficient basis for the opinion, and how that experience is reliably applied to the facts."80
Here, the Court finds that Mattina is qualified to tender the opinions in his affidavits. Mattina has worked in the roofing business for over twenty-nine years and is the president and COO of Crist Roofing & Construction, Inc., ("Crist"), a licensed general contractor with a specialty in roofing.81 Since he joined Crist, Mattina has supervised approximately 12,000 re-roofing projects.82 As part of his oversight responsibilities, Mattina ensures that the roofing projects are being performed in accordance with "all applicable industry standards, building codes, and manufacturer's recommendations."83 Thus, Mattina has extensive experience in the roofing industry. Nevertheless, Mattina fails to establish that his opinions are based on a reliable methodology. Mattina opines that the "Chalet Shingles fail early in their useful life by developing blisters, excessively lose their granules and exhibit highly visible thermal heat cracking."84 He also states that the premature failure is not caused by installation issues, but by the defects he observed during Crist's roofing projects.85 Other than stating that Crist has replaced approximately 1,000 Chalet roofs, however, Mattina fails to explain in his affidavit how he developed his opinion. In his deposition testimony, Mattina stated that he observed many roofs where blistering caused a leak.86 But he did not record the number of leaks he observed, nor did he investigate other possible causes of the leaks.87 Thus, Mattina has failed "to explain how [his] experience led to the conclusion[s] he reached, why that experience was a sufficient basis for the opinion, and just how that experience was reliably applied to the facts of the case."88 In addition, because his opinions are based on roofs that have been replaced, Atlas will not have the opportunity to inspect the roofs and develop its own expert opinions. This, too, leads the Court to conclude that the Defendant's Motion to Exclude Mattina's testimony should be granted.
B. Class Definition
Though not explicitly stated in Rule 23, it is well accepted that "[b]efore a district court may grant a motion for class certification, a plaintiff . . . must establish that the proposed class is adequately defined and clearly ascertainable."89 "An identifiable class exists if its members can be ascertained by reference to objective criteria."90 The analysis of the objective criteria must be administratively feasible, meaning identifying class members is a "manageable process that does not require much, if any, individual inquiry."91 "A proponent of class certification may rely on the defendant's business records to identify prospective class members, but it is not enough to simply allege that the defendant's records will allow for identification."92 "[T]he plaintiff must also establish that the records are in fact useful for identification purposes."93
Here, the Plaintiffs seek certification of the following Rule 23(b)(3) class:
All those who as of the date class notice is issued: (a) own a home or other structure in the State of Georgia on which Atlas Chalet or Stratford roofing shingles are currently installed; or (b) incurred unreimbursed costs to repair or replace Atlas Chalet or Stratford roofing shingles on a home or other structure which they currently own or previously owned in the State of Georgia.94
The Defendant raises two objections to the proposed class definition. First, it argues that the class definition is overly broad. By including current and former owners who incurred costs in repairing or replacing their roofs, the Defendant contends that the class definition does not require the owners to have suffered any damage due to an alleged manufacturing defect. The Defendant also argues that the class is not ascertainable. It contends that determining who qualifies as a member under the second category would require "mini-trials."95
The Court agrees with both of the Defendant's objections. For the Defendant's first objection, the Court finds that this issue is better addressed in its predominance discussion. The Plaintiffs allege that every Shingle is defective, and so the question becomes whether the former and current owners can prove that the alleged defect caused their injuries — the replacement or repair costs of their roofs — or was due to other causes. This causation question raises concerns regarding individualized evidence, and thus the Court will address it in the predominance section of its Order. Still, the Plaintiffs have failed to demonstrate that identification of Atlas Chalet/Stratford Shingles is administratively feasible. The Defendant did not sell Shingles directly to homeowners. The Plaintiffs contend that there are reliable methods for determining membership, including markings on the Shingles, warranty claims, and receipts.96 But other than a list of warranty claims made in Georgia, the Plaintiffs have failed to put forth evidence demonstrating how class members can be easily ascertained.97 The Defendant has offered evidence that most warranty claims were generated by roofers soliciting business by advertising that the Atlas Shingles were defective. And the warranty claims only represent a tiny fraction of the homes with Atlas Shingle roofs. In addition, the Plaintiffs do not proffer evidence that demonstrates each Shingle contains a marking indicating it is an Atlas Chalet or Stratford Shingle. This potentially means a large number of class members' Shingles will need to be individually examined to determine whether they are Chalet/Stratford Shingles. That is exactly the kind of individual inquiry the ascertainability requirement is meant to protect against.98 The Plaintiffs also do not submit any receipts, invoices, or credit card records that demonstrate using such records is a viable option for identifying class members. Merely noting that such records could be used is insufficient to demonstrate ascertainability.99 In sum, the Court finds that the Plaintiffs fail to demonstrate an administratively feasible mechanism for identifying class members in either category of the class definition.100 Without a clearly ascertainable class, the Court cannot grant class certification.101 Nevertheless, because the Court's Order is subject to immediate appeal under Rule 23(f), the Court will address the requirements of Rule 23(a) and 23(b)(3) to determine whether the Plaintiffs would otherwise be entitled to class certification.102
C. Rule 23(A)
To satisfy the numerosity requirement, the Plaintiffs must show that joinder of all members of the putative class would be "impractical."103 "Practicability of joinder depends on many factors, including, for example, the size of the class, ease of identifying its numbers and determining their addresses, facility of making service on them if joined and their geographic dispersion."104 "[W]hile there is no fixed numerosity rule, generally less than twenty-one is inadequate, more than forty adequate, with numbers between varying according to other factors."105
The Plaintiffs have met their burden with regard to numerosity. They have presented evidence that, in Georgia, Atlas has received warranty claims involving 2,752 separate properties.106 Moreover, Atlas Roofing's sales record reveals that it has sold 3,762,062 Chalet Shingles in Georgia, which, based on the Plaintiffs' estimates, means there are about 125,402 homes in Georgia with Chalet Shingles.107 The Plaintiffs, therefore, have presented sufficient evidence that the likely number of homeowners in Georgia who fall within the class exceeds the minimum threshold. Moreover, the large number of putative class members makes joinder impractical. Thus, the Court finds the numerosity requirement is satisfied.
The commonality requirement is satisfied if the plaintiffs demonstrate the presence of questions of law or fact common to the entire class.108 It is not necessary that all questions of law and fact be common.109 Indeed, "[e]ven a single [common] question" is sufficient to satisfy the commonality requirement.110 But the issues still must be susceptible to class-wide proof, and the plaintiffs' claims must share "the same essential characteristics as the claims of the class at large."111 "Commonality requires the plaintiff to demonstrate that the class members `have suffered the same injury.'"112 "This does not mean merely that they all suffered a violation of the same provision of law."113 "Their claims must depend upon a common contention . . . of such a nature that it is capable of classwide resolution — which means that determination of its truth or falsity will resolve an issue that is central to the validity of each one of the claims in one stroke."114
Here, the Court finds that the Plaintiffs have sufficiently demonstrated commonality. The Plaintiffs allege that the Shingles suffer from a common defect due to a flaw in the manufacturing process. Thus, some common issues include: (1) whether the Shingles are defective; (2) whether the defect is caused by a flawed manufacturing process; (3) whether the defect causes the Shingles to suffer from blistering, cracking, and granule loss problems as well as premature failure; (4) whether the defect in the Shingles breached the Defendant's expressed and implied warranties; and (5) whether the Defendant knew of the defect.115 These questions of fact are common to the Plaintiffs' claims and will generate common answers.116 Accordingly, the Plaintiffs have satisfied the commonality requirement.
The typicality requirement mandates that the claims and defenses of the representative plaintiffs are typical of the claims and defenses of the class.117 This requirement is satisfied when "a plaintiff's injury arises from or is directly related to a wrong to a class, and that wrong includes the wrong to the plaintiff."118 But "[c]lass members' claims need not be identical to satisfy the typicality requirement."119 This is because "typicality measures whether a sufficient nexus exists between the claims of the named representatives and those of the class at large."120 "A sufficient nexus is established if the claims or defenses of the class and the class representative arise from the same event or pattern or practice and are based on the same legal theory."121
Here, the Plaintiffs' claims arise from the same allegations of wrongful conduct as the claims of the putative class. Specifically, all the claims are based on the sale of Shingles which allegedly suffer from the same defect. Moreover, the Plaintiffs' claims arise from the same legal theories, including breach of express and implied warranties and fraudulent concealment. In response, the Defendant argues that, based on the experiences of the named Plaintiffs, there is no typical plaintiff, and that individualized defenses render the Plaintiffs' claims atypical. To be sure, the named Plaintiffs each experienced different weather conditions, installation, and maintenance of their roofs. In addition, the named Plaintiffs' warranties are not necessarily typical of the class as a whole. Nevertheless, "the showing required for typicality is not demanding."122 Varying experiences and unique defenses do not necessarily defeat typicality.123 If a "sufficient nexus" exists — as the Court found above — then the typicality requirement is met. Thus, the Court concludes that the Plaintiffs have satisfied Rule 23(a)'s typicality requirement.
4. Adequacy of Representation
To prove adequacy of representation, a plaintiff must demonstrate that the class representatives "fairly and adequately protect the interests of the class."124 This requirement serves to uncover conflicts of interest between named parties and the class they seek to represent.125 A determination of adequacy "encompasses two separate inquiries: (1) whether any substantial conflicts of interest exist between the representatives and the class; and (2) whether the representatives will adequately prosecute the action."126 The Court finds that the named Plaintiffs and their counsel adequately represent the class. First, there is no evidence of any conflicts of interest between the named Plaintiffs and the class. As noted above, the named Plaintiffs and the putative class members seek to recover from the same alleged unlawful conduct — a defect in the Defendant's Shingles. Second, there is no evidence that the named Plaintiffs will not vigorously and adequately pursue the asserted claims on behalf of the class members. Third, there is no evidence of any potential conflicts with class counsel. Moreover, the Plaintiffs have presented evidence that proposed class counsel have extensive experience with class actions and are qualified to conduct this litigation.127 Thus, the Plaintiffs have satisfied Rule 23(a)(4).
D. Rule 23(b)(3)
The Plaintiffs seek class certification under Rule 23(b)(3). To certify a Rule 23(b)(3) class, the Plaintiffs must demonstrate two prerequisites: predominance and superiority.128 To meet the predominance requirement, "the issues in the class action that are subject to generalized proof and thus applicable to the class as a whole, must predominate over those issues that are subject to individualized proof."129 "Common issues of fact and law predominate if they ha[ve] a direct impact on every class member's effort to establish liability and on every class member's entitlement to injunctive and monetary relief."130 Importantly, "[w]hether an issue predominates can only be determined after considering what value the resolution of the class-wide issue will have in each class member's underlying cause of action."131 But if the "plaintiffs must still introduce a great deal of individualized proof or argue a number of individualized legal points to establish most or all of the elements of their individual claims," then predominance does not exist.132
In Brown v. Electrolux Home Products, Inc., the Eleventh Circuit provided a three-step approach for evaluating predominance: (1) identify the parties' claims and defenses and their elements; (2) determine whether these issues are common questions or individual questions by analyzing how each party will prove them at trial; and (3) determine whether the common questions predominate.133 In addition, the Eleventh Circuit noted that "[d]istrict courts should assess predominance with its overarching purpose in mind — namely, ensuring that `a class action would achieve economies of time, effort, expense, and promote . . . uniformity of decision as to persons similarly situated, without sacrificing procedural fairness or bringing about other undesirable results.'"134
a. Breach of Express and Implied Warranties
In Counts I and II of their Complaint, the Plaintiffs allege that the Defendant violated its express and implied warranties. To recover for breach of an express warranty, a plaintiff must show that the defendant made an affirmation of fact or promise which relates to the goods and became part of the basis of the bargain.135 Next, the plaintiff must demonstrate that there is a defect which breaches the express warranty.136 If "notice to the manufacturer within a specified time is a condition precedent to recovery on a breach of warranty claim," then the plaintiff must also show that notice was provided and that the warrantor was given a reasonable amount of time to remedy the defect.137 For breach of implied warranty, a plaintiff must show that there was a defect, that the defect existed at the time of sale, and that the defect made the product unmerchantable.138 Finally, for both warranty claims, a plaintiff must demonstrate that he or she "sustained recoverable damages as the proximate result" of the breach of the warranty.139
Here, the Court finds that — even if the Plaintiffs could prove a uniform defect — individual issues going to causation, notice, coverage, and statute of limitations predominate over any common questions in this case. To begin, there are numerous reasons a roof may fail, including commonplace events and ordinary wear and tear.140 There are also numerous reasons a shingle may blister, crack, or suffer from granule loss.141 Thus, it is likely that the Defendant will bring at least one causation challenge against most — if not all — putative class members. Because the causation determination for most putative class members will involve individualized evidence, these individual causation questions will predominate at any trial.142 In response, the Plaintiffs argue that if the jury agrees with their argument that a defect existed in every Shingle at the time it was sold, then Atlas's arguments regarding alternative causation will be negated.143 Not so. Because the Plaintiffs seek the replacement costs of all class members' roofs, the alleged defect in the Shingles must have caused a class member's injuries in order for that class member to recover.144 All roofs will fail eventually. If an Atlas Shingle roof survives to the end of normal roof life expectancy, the homeowner-class member has not been damaged by the alleged manufacturing defect. If the roof fails due to hail or wind damage or improper installation, the homeowner-class member has not been damaged. This is unlike a products liability case where the plaintiffs claim an economic injury by seeking the diminution in the intrinsic value of the product.145 In such cases, the plaintiffs typically only need to prove that the defect existed at the time of purchase to prove the defect caused their economic injury.146 Here, even if the Plaintiffs prove a common defect existed in the Shingles, each class member cannot recover damages based on that fact alone. They also must prove that the alleged defect caused their roof to prematurely fail. For the Plaintiffs that have already had their roofs replaced or repaired, this will be an especially fact-intensive inquiry.
The Plaintiffs cite two cases — Sanchez-Knutsen v. Ford Motor Co. and Brooks v. GAF Materials Corp. — which they contend support their argument. However, the Court finds that these cases do not help the Plaintiffs. In Sanchez-Knutsen, the court dismissed the need for individual inquiries into causation, concluding that the evidence did not justify the defendant's concerns.147 At issue was whether Ford's Explorer vehicle suffered from a defect at the time of purchase that permitted exhaust and other gases to enter the passenger compartment of the vehicle.148 The court in Sanchez-Knutsen framed the plaintiffs' damages as the diminution in the intrinsic value of their Explorers, not the repair costs.149 Thus, the court did not face the same causation issues presented in this instant case. Here, each class member will need to prove that the alleged defect caused his or her Shingles to prematurely fail, not just that the defect exists. This will likely create substantial causation inquiries when deciding the class members' claims.
Brooks is also distinguishable. There, homeowners sued GAF Materials Corp. ("GAF"), which manufactures roofing materials, over allegedly defective roof shingles.150 Specifically, the named plaintiffs sought to represent a class of individuals whose shingles allegedly prematurely cracked.151 In certifying the proposed class, the court discounted the need for individual causation inquiries, stating that the "Plaintiffs seek to establish causation on a large scale — that GAF knowingly sold shingles that contained an inherent manufacturing defect that will inevitably cause the shingles to crack, split, or tear."152 While the Plaintiffs, here, present a similar causation argument, the Court believes that evidence in this case demonstrates that other specific causation issues — such as improper installation, inadequate ventilation, or environmental factors — will be significant in deciding the putative class members' cases. Moreover, the class in Brooks was limited to persons whose shingles had already cracked, split, or torn.153 Here, the breadth of the Plaintiffs' proposed class is much larger — it includes owners whose roofs may have been repaired or replaced for reasons other than the alleged premature failure. As a result, the Plaintiffs' proposed class presents more individualized causation questions.
Individual issues will also predominate with respect to two requirements in Atlas's express warranty: transferability and notice. Transferability presents individual questions because the 2002 limited warranty specifically requires a second owner to notify Atlas in writing within thirty days of the real estate transfer for any coverage to be transferred.154 The third-owner class members are not even eligible to recover under the 2002 limited warranty.155 As a result, the class members who purchased a home with Atlas Shingles already installed on it will have to prove that the warranty properly transferred to them. Proving compliance with Atlas's notice requirement will require even more individualized evidence. The 1999 limited warranty requires each warrantee to provide notice of the alleged defect to Atlas within five days of discovering it, and the 2002 limited warranty requires notice within thirty days of discovery.156 Each class member will then need to demonstrate that his or her notice to Atlas was for the alleged defect and not for an unrelated issue. Finally, each class member will need to demonstrate that he or she provided Atlas an opportunity to cure the alleged defect. There are, therefore, numerous individualized issues that will predominate the issues of notice and transferability.
In response, the Plaintiffs first argue that evidence of numerous consumer complaints regarding the alleged defect may be used to satisfy the notice requirement. They cite several cases where courts have found that widespread consumer complaints are sufficient to establish constructive notice.157 But Georgia courts have yet to recognize constructive notice in this context. As a result, the Court is unwilling to hold that constructive notice is sufficient to satisfy the notice requirement.158 The Plaintiffs then argue that, through common evidence, they will demonstrate the Defendant waived the notice requirement. According to the Plaintiffs, the Defendant never asked the warranty claimants whether they were filing their claims within thirty days of discovering the alleged defect. Nor did the Defendant enforce the requirement when it knew the claimants were late. The Plaintiffs cite RHL Properties LLC v. Neese159 in support of their contention. There, the Georgia Court of Appeals stated that courts "will readily find a waiver of strict compliance with a notice provision based on the conduct of the parties in order to avoid a forfeiture of substantive contractual rights."160 Thus, the Plaintiffs argue that by routinely failing to insist on compliance with the notice requirement, the Defendant waived the requirement. The Court disagrees. The Neese case concerned whether the defendant waived its notice requirement with respect to one party.161 The Plaintiffs have failed to cite any case law that states a defendant may waive the notice requirement with respect to all of its warranty claimants if it does not enforce the requirement for each past claimant. Consequently, the Court finds that the notice and opportunity to cure requirement is an individual issue that cannot be resolved through common evidence.
Atlas is also likely to employ affirmative defenses against many class members, with the most likely defense being the statute of limitations. Under Georgia law, "[a]n action for breach of any contract for sale must be commenced within four years after the cause of action has accrued."162 Typically, the cause of action accrues when the breach occurs, which for a warranty occurs when tender of delivery is made.163 The implied warranty claim will follow the typical accrual rule.164 For that claim, all of the putative class members will need to demonstrate that they purchased their Shingles within the last four years. But as the Defendant correctly pointed out during the class certification hearing, based on Atlas's sales data, only 5% of the Shingles were sold in the last four years.165 Thus, it is likely a large percentage of the class members' implied warranty claims will be barred by the statute of limitations.166
The Plaintiffs counter with the general rule that individual affirmative defenses usually do not defeat predominance.167 Thus, they contend that the statute of limitations issue, along with other potential affirmative defenses, can be handled in the second phase of the case after a liability trial. It is accurate that "courts traditionally have been reluctant to deny class action status under Rule 23(b)(3) simply because affirmative defenses may be available against individual members."168 But as the Eleventh Circuit recently confirmed in Brown v. Electrolux Home Products, Inc., affirmative defenses are nevertheless relevant when determining the question of predominance.169 Specifically, the Eleventh Circuit noted that affirmative defenses that are coupled with several other individual questions could defeat predominance.170 Such is the case here. The statute of limitations defense coupled with the other individual issues discussed above outweigh any common questions raised by the Plaintiffs.
b. Fraudulent Concealment
In Count VI of their Complaint, the Plaintiffs assert a fraud claim against the Defendant. The Plaintiffs argue that Atlas fraudulently concealed the alleged defect and misrepresented to potential customers that the Shingles were durable and conformed to applicable industry standards. To prove their allegation, the Plaintiffs point to evidence — including internal documents — that allegedly demonstrates the Defendant was aware of the defect.171 "The tort of fraud has five elements: (1) a false representation or omission of a material fact; (2) scienter; (3) intention to induce the party claiming fraud to act or refrain from acting; (4) justifiable reliance; and (5) damages."172 Because the element of reliance is more hotly disputed than the other elements, the Court's analysis will focus on it.
The Defendant contends that, in the instant case, reliance is an individual issue that cannot be proven through common evidence. It points to Huddleston v. R.J. Reynolds Tobacco Co., in which this Court held that in Georgia — even in the context of fraudulent omissions — reliance must be proven on an individual basis.173 Thus, according to the Defendant, the individual issues surrounding reliance on the allegedly fraudulent misrepresentations and omissions defeat predominance. The Plaintiffs counter that "under well-established Eleventh Circuit precedent, the simple fact that reliance is an element in a cause of action is not an absolute bar to class certification."174 They then go one step further and state that the class members will be able to use circumstantial evidence when demonstrating reliance. They point to Klay v. Humana, Inc. in support of their contention. In Klay, a putative class action was brought by a group of doctors who submitted claims for reimbursement to HMOs but were systematically underpaid.175 The court concluded that class certification was appropriate for the plaintiffs' RICO claim for two reasons. First, common issues of fact, which included the existence of a national conspiracy, a pattern of racketeering activity, and a Managed Care Enterprise, predominated "over all but the most complex individualized issues."176 Second, the court found "that, based on the nature of the misrepresentations at issue, the circumstantial evidence that can be used to show reliance is common to the whole class."177 In clarifying the nature of the misrepresentations, the Eleventh Circuit stated:
The alleged misrepresentations in the instant case are simply that the defendants repeatedly claimed they would reimburse the plaintiffs for medically necessary services they provide to the defendants' insureds, and sent the plaintiffs various EOB forms claiming that they had actually paid the plaintiffs the proper amounts. While the EOB forms may raise substantial individualized issues of reliance, the antecedent representations about the defendants' reimbursement practices do not. It does not strain credulity to conclude that each plaintiff, in entering into contracts with the defendants, relied upon the defendants' representations and assumed they would be paid the amounts they were due. A jury could quite reasonably infer that guarantees concerning physician pay — the very consideration upon which those agreements are based — go to the heart of these agreements, and that doctors based their assent upon them.178
The Plaintiffs contend that the misrepresentations in Klay are similar to the misrepresentations by Atlas in that no class member would purchase Shingles that are going to prematurely fail. Therefore, all the class members relied on Atlas's alleged omission and misrepresentations regarding the durability of the Shingles when they purchased the Shingles.
The Plaintiffs' analogy is misplaced. "[A] fraud case may be unsuited for treatment as a class action if there was material variation in the representations made or in the kinds of degrees of reliance by the persons to whom they were addressed."179 When presented with such cases, "the Eleventh Circuit has repeatedly found class certification inappropriate."180 In this case, there are both material variation in the representations and kinds of degrees of reliance by the class members. For the alleged misrepresentations, each class member would need to establish what particular marketing material or industry standard he or she observed and relied upon. This is further complicated by third party wholesalers, retailers, and contractors who made the purchase decisions for the vast majority of the Shingle purchases. Indeed, there is no evidence that Atlas engaged in a uniform marketing scheme. Thus, the Plaintiffs cannot use common evidence to prove they relied on Atlas's statements regarding the durability of the Shingles. For the alleged fraudulent omission, the class members made their own assessment when deciding to purchase the Shingles or homes with the Shingles installed on the roof. As an example, some class members may have been on notice of blistering, cracking, and granule loss on the Shingles, but decided to purchase the property despite the conditions. Such class members would not have relied on the alleged omission. Unlike in Klay, the class will need to prove reliance through individual evidence. Thus, the Court finds that common issues do not predominate with regard to the Plaintiffs' fraudulent inducement claim.181
To meet the superiority requirement, the Court must conclude "that a class action is superior to other available methods for fairly and efficiently adjudicating the controversy."182 The factors relevant in determining superiority include:
(A) the class members' interests in individually controlling the prosecution or defense of separate actions;
(B) the extent and nature of any litigation concerning the controversy already begun by or against class members;
(C) the desirability or undesirability of concentrating the litigation of the claims in the particular forum; and
(D) the likely difficulties in managing a class action.183
Class certification "cannot be denied because the number of potential class members makes the proceeding complex or difficult."184 But the difficulties in managing a class are important "if they make the class action a less fair and efficient method of adjudication than other available techniques."185 Thus, the focus should be "on the relative advantages of a class action suit over whatever other forms of litigation might be realistically available to the plaintiffs."186
The Court finds that class treatment is not superior to other available methods of adjudication. Based on the number of individual issues discussed above, adjudicating these claims on a class-wide basis will likely present a manageability problem. There will be numerous fact-intensive individual inquiries, including physical inspection of class members' Shingles and individual testimony regarding when class members discovered the defect and provided notice to Atlas. In addition, the Court does not agree with the Plaintiffs' contention that the class members lack any significant interest in controlling the litigation. The damages claimed by the named Plaintiffs are not insignificant. The Plaintiffs' own expert opined that replacing a roof can be "several thousand dollars to tens of thousands of dollars."187 Thus, this case is unlike class actions where the class members have suffered only a minor harm and would not pursue their claim but for the class action mechanism.188 The owners have the option of pursuing their claims in state court, where claims of several thousands dollars are common.189 In sum, the Court finds that Rule 23(b)'s superiority requirement is not satisfied.
E. Rule 23(c)(4)
As an alternative, the Plaintiffs ask the Court to certify a Rule 23(c)(4) class consisting of four common questions: "(1) whether the shingles suffer from a common manufacturing defect; (2) whether the defect breaches any express or implied warranties; (3) whether the defect necessitates replacement of all roofs containing the shingles; and (4) whether Atlas fraudulently concealed the defect."190 The Plaintiffs contend that certifying a class based on these four questions will materially advance the litigation.
Under Rule 23(c)(4), "an action may be brought or maintained as a class action with respect to particular issues."191 However, there is a split among courts over how to apply the predominance test when asked to certify an issue class.192 Some courts have certified issue classes despite a lack of overall predominance.193 But many other courts "have emphatically rejected attempts to use the (c)(4) process for certifying individual issues as a means for achieving an end run around the (b)(3) predominance requirement."194 These courts note that "the proper interpretation of the interaction between subdivisions (b)(3) and (c)(4) is that a cause of action, as a whole, must satisfy the predominance requirement of (b)(3) and that (c)(4) is a housekeeping rule that allows courts to sever common issues for a class trial."195 The Court finds the latter interpretation to be persuasive.196 As discussed above, even if the Plaintiffs could establish in a class-wide trial that the Shingles suffer from a common manufacturing defect, each class members' claim will still need to be separately tried to determine issues like causation, notice, and statute of limitations. It is these individual issues that will predominate. Moreover, certifying an issues class would not promote judicial efficiency. The "Plaintiffs' case for certification collapses when it confronts the fact that certification of a common issues class will not dispose of a single case or eliminate the need for a single trial."197 As a result, the Court concludes a Rule 23(c)(4) class should not be certified.
For the reasons set forth above, the Plaintiffs' Motion for Class Certification [Doc. 57] is DENIED.
