    MEMORANDUM OPINION
    This appeal involves a dispute between a roofing subcontractor that installed
    roofs on two apartment buildings in Montgomery County and the entity that
    manufactured the roofing materials the subcontractor used to build the roofs.
    Following a bench trial, the trial court found in the subcontractor’s favor and
    awarded damages. The manufacturer appealed and filed a brief, which raises ten
    issues for our review. We conclude the manufacturer’s issues are either without
    1
    merit or were not properly preserved for appellate review. Thus, we affirm the
    judgment the trial court signed following the trial.
    Background
    The appellant, U.S. Ply, Inc., manufactures and sells an array of roofing
    materials used on commercial buildings. The performance of one of its products—
    RapidGRIP—is the product that lies at the heart of the parties’ dispute. The evidence
    in the trial shows that RapidGRIP comes in rolls and that commercial roofing
    contractors use it in several applications to build commercial roofs. One of these
    involves using RapidGRIP as the middle layer of a three-ply roofing system.
    RapidGRIP is useful for this purpose because when correctly installed, it firmly
    bonds with the other two layers of roofing material. When finished, this category of
    roof is known as a three-ply, modified-bitumen roof.
    ARCI, Ltd. is the subcontractor that purchased RapidGRIP and used it on the
    roofs that were the subject of the trial. The parties tried the case to the bench. By its
    verdict, the trial court found that the manufacturer misrepresented the qualities of
    the RapidGRIP to the subcontractor in connection with its purchase of RapidGRIP,
    that the manufacturer violated express and implied warranties associated with the
    sales, and that the repairs the subcontractor performed to correct the problems on the
    roofs, allegedly associated with the RapidGRIP’s failure to create a sufficient bond
    2
    to the ply that it covered, were reasonable and necessary. The trial court also found
    that the subcontractor did not fail to store the RapidGRIP properly before using it or
    fail to follow any of the manufacturer’s instructions and industry standards that were
    material to properly installing the modified-bitumen roofs.
    U.S. Ply’s product information sheet for RapidGRIP describes the product as
    a “SBS (Styrene-Butadiene-Styrene) self-adhering membrane[,] [m]anufactured
    with a strong fiberglass mat that is saturated and coated with a premium quality,
    ‘high tack’ asphaltic bitumen that is combined with durable SBS elastomers and
    protected by a poly release film for easy installation.” The label indicates that
    RapidGRIP, in some roofing systems, may be “cold applied, SBS torch applied and
    SBS mop applied assemblies where applicable.” In January and February 2013,
    ARCI used RapidGRIP as the middle layer of a three-ply, modified-bitumen asphalt
    roofing system on two apartment buildings that were built in Montgomery County.
    ARCI performed the work as a subcontractor working for the general contractor on
    the project, Construction Supervisors, Inc. The parties refer to the construction
    project as “Sunningdale,” as do we.
    The testimony in the trial shows that before building the roofs at Sunningdale,
    ARCI had over thirty years of experience installing roofs on commercial buildings,
    which included successfully building between 2,500 and 3,000 modified-bitumen
    3
    roofs using a self-adhering roofing membrane manufactured by one of U.S. Ply’s
    competitors. Before using RapidGRIP at Sunningdale, however, ARCI had never
    used that brand of roofing membrane. The testimony from the trial shows that before
    ARCI decided to use RapidGRIP on its project at Sunningdale, ARCI’s president,
    Jody Born, contacted Shawn Walker, a representative for U.S. Ply. Jody and Walker
    met to discuss using U.S. Ply’s roofing products on the modified-bitumen roofs
    ARCI planned to build at Sunningdale. Jody testified that he told Walker about the
    products ARCI traditionally used to build modified-bitumen roofs, and that the
    roofing membrane they were using could be applied cold—that is, without using a
    torch. Jody explained that Walker told him that RapidGRIP was “as good or better”
    than the brand of roofing membrane ARCI had been using for this type roof.1
    By late January or early February 2013, ARCI finished installing the
    RapidGRIP on roofs it built on the apartments at Sunningdale. As ARCI’s work
    neared completion, the project’s architect hired Building Exterior Solutions, L.L.C.
    (BES) to inspect the roofs to determine whether they were substantially complete.
    BES inspected the roofs in mid-February 2013 and then issued a report. In its report,
    BES noted five types of deficiencies in the roofs, including “[u]n-adhered laps in the
    1
    Walker did not testify in the trial, and Jody’s testimony is the only testimony
    in the record explaining what he and Walker discussed that led ARCI to switch from
    the products it had been using to U.S. Ply’s products for these roofs.
    4
    adhered base sheet.” The testimony and documents in evidence show the RapidGRIP
    membrane did not bond with the ply it was used to cover over large areas on both
    apartment’s roofs.
    In early April 2013, U.S. Ply signed an agreement with ARCI defining the
    scope of repairs and materials required to correct the problems associated with the
    RapidGRIP on one of the apartment buildings at Sunningdale. The parties refer to
    that building as building two. They refer to the building that U.S. Ply never agreed
    to repair as building one.
    Under the repair agreement, U.S. Ply agreed to pay ARCI $57,524 for the
    labor required to repair the roof on building two with roofing materials that were
    supplied by U.S. Ply. BES recommended repairs due to problems with the
    RapidGRIP on both roofs. ARCI proceeded to repair the roofs on both buildings
    even though U.S. Ply only agreed to pay for the repairs to building two. On building
    two, ARCI replaced the roof under the terms of its repair agreement with U.S. Ply.
    To repair the roof on building one, ARCI added two additional layers of roofing
    material over the existing roof pursuant to the recommendation by BES to repair the
    roof that way.
    Although ARCI provided the labor to repair the roof on building two, U.S.
    Ply never paid for the repairs based on the requirements of the written agreement
    5
    covering that building. In March 2014, U.S. Ply placed a check for $57,524 into the
    registry of the district court and sued ARCI seeking a declaratory judgment stating
    that it owed ARCI nothing for repairing the two roofs. U.S. Ply asked the trial court
    to declare the parties’ rights. In response to the suit, ARCI counterclaimed, alleging
    that U.S. Ply was guilty of deceptive trade practices, had misrepresented the qualities
    of the RapidGRIP, and breached implied and express warranties accompanying
    ARCI’s purchases of the RapidGRIP it used at Sunningdale. ARCI’s live pleading
    alleges that in connection with ARCI’s purchases of U.S. Ply’s brand of roofing
    products, U.S. Ply represented that RapidGRIP is “self-adhering[,]” “would fully
    adhere[,]” and “that there was no additional attachment method needed” to install
    the product. U.S. Ply’s live pleadings deny that the RapidGRIP used at Sunningdale
    failed to bond to the lower ply of the roofs on which it was used, that the RapidGRIP
    was defective, or that U.S. Ply misrepresented anything about RapidGRIP in
    connection with ARCI’s purchase of its products.
    In late 2016, the case went to trial. Before the trial began, the trial court re-
    aligned the parties, making ARCI the plaintiff and U.S. Ply the defendant. Thirteen
    witnesses testified over the course of a four-day trial. ARCI and U.S. Ply called
    expert witnesses, and each discussed why the RapidGRIP used at Sunningdale failed
    to bond to the bottom ply of the modified-bitumen roofs.
    6
    In mid-January 2017, the trial court signed a judgment awarding ARCI
    $171,105 in damages and $224,200 in attorney’s fees, plus conditional awards of
    attorney’s fees dependent on whether ARCI prevailed through each stage of any
    appeals. In mid-February 2017, U.S. Ply moved for new trial. It also filed a request
    asking that the trial court provide the parties with written findings of fact and
    conclusions of law. The trial court never filed written findings, and U.S. Ply filed a
    timely notice of appeal.
    Issues
    U.S. Ply raises ten issues for our review in its brief. For convenience, we group
    and then analyze them under four headings: (1) is the evidence legally and factually
    sufficient to support the judgment; (2) did ARCI’s alleged failure to follow U.S.
    Ply’s instructions and industry standards when installing the RapidGRIP waive its
    right to recover on ARCI’s implied and express warranty claims; (3) was the
    testimony of Bradley Hughes, ARCI’s roofing expert, properly admitted and does it
    provide reliable support for the verdict; and (4) did ARCI preserve its right to obtain
    the trial court’s written findings regarding the verdict.
    Standard of Review
    Four of U.S. Ply’s appellate issues argue the evidence is legally and factually
    insufficient to support the trial court’s verdict. We address the standard for those
    7
    issues here. In an appeal from a bench trial, the trial court’s findings of fact are
    reviewable under the same legal and factual sufficiency standards that are used to
    determine whether the evidence admitted during a trial is sufficient to support the
    jury’s answer to the jury charge.2 Stated another way, the trial court’s factual
    findings “have the same force and dignity as a jury’s verdict[.]” 3 When parties try
    the case to the bench, the trial court acts as the factfinder and judges the credibility
    of the witnesses, the weight to give to the testimony, and resolves any
    inconsistencies that may exist in the evidence before it in the trial.4 In reviewing
    findings of fact, we credit evidence that supports the verdict if the trial court could
    have done so, and we disregard evidence that is inconsistent or contradicts the trial
    court’s findings unless the court, given the evidence before it, could not have
    resolved the conflict in a way that favors its verdict.5

    Here, the trial court failed to provide the parties with written findings of fact
    and conclusions of law in response to U.S. Ply’s first request asking for them. U.S.
    Ply, however, then failed to notify the trial court that its findings were past due. 6 In
    the absence of written findings, we imply all findings of fact needed to support the
    judgment if there is evidence to support them. 7
    Under the legal-sufficiency standard of review, we consider the evidence
    admitted in the trial in the light that most favors the findings the appellant is
    challenging in the appeal. 8 We indulge every reasonable inference that can be made
    from the evidence in favor of the trial court’s verdict, and then we determine whether
    the legally sufficient evidence was admitted during the trial to support the trial
    court’s verdict.9 If the trial court could have credited the evidence that it considered
    in favor of its verdict, we will too, and we must disregard evidence contrary to the
    verdict unless it is evidence the trial court could not have reasonably decided to

    Ultimately, after viewing the evidence in a favorable light, we must decide
    if the finding the appellant is challenging was reasonable given the evidence
    admitted in the trial.11
    When the appellant raises factual-sufficiency complaints in its appeal, we
    examine all the evidence admitted in the trial to evaluate whether the evidence is
    factually sufficient to support the trial court’s verdict.12 When conducting a factual-
    sufficiency review, we view the evidence in a neutral light, and we are not authorized
    to set aside the findings being challenged unless the overwhelming weight of the
    evidence is contrary to the implied findings such that the verdict is wrong and
    unjust. 13
    When reviewing a trial court’s conclusions of law, we apply a de novo
    standard. 14 On appeal, we cannot review a trial court’s legal conclusions for factual

    insufficiency. 15 Instead, the trial court’s legal conclusions are reviewable to
    determine whether the trial court properly applied the law to the facts of the case. 16
    1. Is the evidence legally and factually sufficient to support the judgment?
    Liability
    In its first, sixth, and seventh issues, U.S. Ply argues the trial court’s judgment
    should be reversed because the trial court’s findings are unsupported by evidence
    that is sufficient to support the trial court’s conclusion that U.S. Ply misrepresented
    RapidGRIP’s qualities or its conclusion that U.S. Ply breached any express or
    implied warranties that accompanied the relevant sales. 17 In support of these
    arguments, U.S. Ply relies heavily on the roofing report of its employee, Clint
    Freeman. Freeeman inspected the roofs in late-February 2013. U.S. Ply also relies
    heavily on a report of BES, authored by its employee Mike Hoecherl. Hoecherl
    15
    
    Id. 16 Id.
          17
    In issue one, U.S. Ply also argues that not enough evidence was before the
    trial court to support its finding that ARCI needed to replace the roof that it installed
    on building one. U.S. Ply makes essentially the same argument in issue six. Because
    the arguments are so similar, we address them together in analyzing U.S. Ply’s sixth
    issue.
    11
    inspected the roofs before they were completed. His report states the “modified
    bitumen roof system[s] [ARCI installed at Sunningdale] were not completed per
    industry standard roofing practices and the roof system manufacturer’s guidelines.”
    According to U.S. Ply, except for Hoecherl’s testimony explaining why the
    RapidGRIP used at Sunningdale failed, the record contains no other admissible or
    reliable evidence explaining why the RapidGRIP ARCI installed malfunctioned.
    In presenting its arguments, and to isolate the testimony the trial court
    considered from ARCI’s roofing expert, Bradley Hughes, U.S. Ply suggests that his
    testimony was both inadmissible and unreliable. According to U.S. Ply, the trial
    court should not have allowed Hughes to testify because ARCI failed to provide it
    with a copy of Hughes’ report by the discovery deadlines in the docket-control order
    that controlled the discovery deadlines in the case. Also, U.S. Ply argues that Hughes
    did not have the qualifications that he needed to determine why the RapidGRIP used
    at Sunningdale malfunctioned. U.S. Ply concludes that without the benefit of
    Hughes’ testimony, the record does not contain legally or factually-sufficient
    evidence to support the implied findings that must be made to support the trial
    court’s verdict. 18
    18
    U.S. Ply advances the same complaints about the admissibility and
    reliability of Hughes’ testimony in issues two through five. We will address U.S.
    Ply’s complaints about Hughes’ qualifications and whether his testimony was
    12
    In general, the record shows that the parties presented the trial court with two
    conflicting theories to explain why the RapidGRIP malfunctioned when it failed to
    bond to the ply of roofing material that it covered. U.S. Ply claimed and produced
    evidence during the trial that ARCI failed to follow U.S. Ply’s instructions for the
    product and to apply the product in accord with industry practices. Yet the record
    also contains evidence that ARCI properly installed the RapidGRIP and followed all
    of the material instructions and prevailing industry standards when installing the
    product. Additionally, the record before the trial court contains substantial evidence
    showing that the RapidGRIP used at Sunningdale would not bond to the ply of
    roofing material it covered without using a torch.
    The final judgment the trial court signed does not specify the legal theory the
    trial court used to reach its verdict. To prevail on appeal, and because the trial court
    did not reduce its findings and conclusions to writing, U.S. Ply must establish that
    ARCI was not entitled to prevail on any of the theories of liability on which it relied
    reliable in discussing those issues. Nevertheless, because we conclude that the trial
    court had the discretion to allow Hughes to testify and to find his testimony reliable,
    we conclude the trial court could reasonably rely on his testimony in reaching its
    verdict.

    at trial. 19 Thus, U.S. Ply must establish in its appeal that the evidence before the trial
    court is insufficient to show that U.S. Ply violated the Deceptive Trade Practices Act
    (DTPA), breached any express warranties, or breached any implied warranties that
    apply to ARCI’s purchases of the RapidGRIP it used at Sunningdale. 20
    Before examining the evidence relevant to ARCI’s DTPA and implied
    warranty of merchantability claims, we examine the record to determine whether the
    evidence supports the trial court’s judgment under ARCI’s express warranty
    theory. 21 During the trial, ARCI claimed that it relied on various representations
    about RapidGRIP’s qualities on the product’s label and representations that Walker
    made during his meeting with Jody. The label on the boxes the RapidGRIP came in
    states the product is a “premium quality, ‘high tack’” membrane and indicates that
    in some applications, RapidGRIP can be applied cold. The testimony in the trial
    19
    See Blackstone Med., Inc. v. Phoenix Surgicals, L.L.C., 
    470 S.W.3d 636
    ,
    648 (Tex. App.—Dallas 2015, no pet.) (“An appellant must attack all independent
    bases or grounds that fully support a complained of ruling or judgment.”).

    See Tex. Bus. & Com. Code Ann. § 2.313(a)(2) (West 2009) (providing that

    an express warranty that the goods shall conform to the description”); 
    id. § 2.314(b)(6)
    (West 2009) (stating that, for a good to be merchantable, it must
    “conform to the promises or affirmations of fact made on the container or label if
    any”);

    represent that goods have characteristics or benefits they do not have).

    See Tex. R. App. P. 47.1.

    reflects that a purchaser’s ability to apply the product cold means the product can be
    applied without using supplemental heat, like a torch, to cause the product to bond
    with the upper and lower plies of a modified-bitumen roof. According to Jody, in his
    meeting with Walker, Walker told him that RapidGRIP is “as good or better” than
    the roofing membrane they were using regarding the quality of the membrane to
    stick on roofs during a conversation when Walker knew that ARCI intended to apply
    the product without using a torch.
    Ultimately, ARCI requested that Construction Supervisors, the general
    contractor on the Sunningdale project, approve its request to use U.S. Ply products
    on the roofs that ARCI was hired to build at Sunningdale. Construction Supervisors
    forwarded the information about the roofs that it got from ARCI to the architect for
    the project and ARCI received the required approvals it needed to use U.S. Ply’s
    products to build the roofs. The written materials that ARCI provided Construction
    Supervisors about RapidGRIP, which originated at U.S. Ply, state that RapidGRIP
    is a self-adhering, high-tack membrane that can be used at ambient temperatures of
    50℉ or higher and when RapidGRIP is at least 70℉ if installed while exposed to
    direct sunlight without using supplemental heat. Based on the testimony about the
    circumstances showing how ARCI chose to use the RapidGRIP brand of roofing
    membrane for its work at Sunningdale, we conclude the record contains legally and
    15
    factually-sufficient evidence to support the trial court’s implied finding that ARCI
    relied on information supplied by U.S. Ply to purchase the RapidGRIP that it used
    on the project. 22
    There is also evidence in the record that supports the trial court’s finding that
    the qualities of the RapidGRIP ARCI used on the project did not conform to the
    product’s label and the representations Walker made about RapidGRIP during his
    meeting with Jody. 23 The testimony in the trial established that Mid-States Asphalt
    manufactures RapidGRIP under specifications provided to it by U.S. Ply. In late-
    March 2013, after BES identified that there was a problem with the RapidGRIP
    ARCI installed on the apartment’s roofs, U.S. Ply sent Mid-States Asphalt a part of
    the leftover roll that ARCI removed from one of the roofs at Sunningdale. U.S. Ply
    asked that Mid-States Asphalt test the roll. In an email, U.S. Ply told Mid-States
    Asphalt that U.S. Ply had conducted its own tests on the leftover roll of RapidGRIP,
    and that its tests showed the RapidGRIP “[could] be easily removed.” Several days
    after sending the leftover roll, U.S. Ply sent a follow-up email to Mid-States Asphalt.
    22
    See Henry Schein, Inc. v. Stromboe, 
    102 S.W.3d 675
    , 686 (Tex. 2002)
    (stating that reliance is an element a plaintiff must prove to show the defendant
    breached an “express warranty (to a certain extent)”).
    23
    See Tex. Bus. & Com. Code Ann. § 2.313(a)(2); Redman Homes, Inc. v.
    Ivy, 
    920 S.W.2d 664
    , 668 (Tex. 1996) (indicating that circumstantial evidence may
    establish a fact issue showing a product malfunctioned).
    16
    The email states: “[T]he RapidGRIP is not sticking to the base on the project. What
    [U.S. Ply] need[s] to know is whether or not the sample provided to you is mating
    properly . . . . or do you need supplemental heat or conditions to make that happen?”
    This email, along with the evidence showing that BES found problems with the
    RapidGRIP installed on the roofs, clearly shows that U.S. Ply wanted to know
    whether the leftover roll could be used for applications like those at Sunningdale
    without a torch because the label indicated the product could be used for that type of
    application if applied properly and within the temperatures that are stated on the
    product’s label.
    In late-March 2013, Mid-States Asphalt tested the leftover roll. After testing
    the roll, Mid-States Asphalt advised U.S. Ply, by email, that proper “adhesion will
    be achieved by simple torching down the finished roof covering over the
    Rapid[GRIP].” About thirty minutes after receiving that email, U.S. Ply replied:
    “That isn’t our question nor concern – it is that it appears that it will not bond without
    a torch which is the complaint – that is what we want an answer to.” About an hour
    later, Mid-States Asphalt informed U.S. Ply that “[using supplemental heat] will
    most definitely solve the problem. . . . So, yes supplemental heat will be required in
    order to facilitate the bond to the substrate. . . . I hope that this answers your
    17
    question.” Later that same afternoon, Mid-States Asphalt offered to replace the
    RapidGRIP that ARCI used on its project.
    We conclude the evidence admitted during the trial allowed the trial court to
    conclude as a reasonable finder of fact that the RapidGRIP failed to bond to the roof
    when applied without using a torch. ARCI installed the RapidGRIP under conditions
    significantly cooler than the conditions when U.S. Ply and Mid-States Asphalt tested
    the leftover roll. The tests on the leftover roll were conducted at around 75℉. U.S.
    Ply’s report about its test of the leftover roll states: “Rapid[GRIP] did not adhere
    very well.”
    U.S. Ply argues the tests on the leftover roll were not relevant because by the
    time the roll was tested, it was no longer in the same or similar condition that it was
    in when it was sold. Based on that argument, U.S. Ply concludes the test results on
    the roll do not explain why the rolls of RapidGRIP ARCI used failed to bond to the
    lower ply of the roofs on which it was installed. To support this argument, U.S. Ply
    points to the evidence in the record from which the trial court might have found that
    ARCI failed to store or to install the RapidGRIP properly. According to U.S. Ply,
    the record establishes that storage and installation errors, not a malfunction in the
    RapidGRIP, explain why the RapidGRIP failed.
    18
    To prove causation on an express warranty claim, the plaintiff must prove the
    breach is a “substantial factor in bringing about” the plaintiff’s injuries.24 According
    to U.S. Ply, the overwhelming great weight and preponderance of the evidence
    shows the RapidGRIP malfunctioned because ARCI failed to store or to install the
    RapidGRIP it acquired properly. U.S. Ply argues that given the evidence about how
    the RapidGRIP was stored and installed, the leftover roll was no longer in a condition
    that it could be tested to determine what condition the rolls were in when ARCI
    acquired them. And it argues that ARCI’s storage and installation errors caused the
    RapidGRIP to malfunction when the rolls did not bond to the roofs.
    The record from the trial contains testimony from which the trial court might
    have found that (1) ARCI failed to roll the RapidGRIP with a weighted roller after
    placing it over the mechanically-fastened ply that it installed on the roofs; (2) ARCI
    did not install the RapidGRIP when the ambient air temperatures were at least 50℉
    and the RapidGRIP rolls were at least 70℉; (3) After ARCI rolled the RapidGRIP
    out on the roof, it then failed to protect its work in progress by covering the
    RapidGRIP with the top ply of roofing material before leaving its work overnight,
    thereby allowing the rolls that it installed each day to be exposed to the weather; (4)

    898 S.W.2d 773
    , 775 (Tex. 1995)).
    19
    ARCI failed to seal the roof in various places before leaving work each day, creating
    another potential source of moisture that could interfere with the RapidGRIP’s
    ability to bond to the other plies of roofing material used to build the roofs; and (5)
    ARCI failed to store the RapidGRIP to protect it from the effects of the weather and
    from sunlight before installing it. With respect to using a weighted roller, there is
    testimony in the record that shows that ARCI failed to use a weighted roller.
    RapidGRIP’s label recommends that to achieve best results, it highly recommended
    rolling the RapidGRIP with a weighted roller. ARCI presented testimony showing
    that it customarily used four-pound brooms to press the roofing membrane into the
    roofing ply the membrane covered to make the plies contact each other, and that it
    followed that practice at Sunningdale. According to Jody, using brooms in the
    manner that ARCI uses them when building modified-bitumen roofs is an acceptable
    practice. He explained that U.S. Ply’s application procedures recommend but do not
    require the use of weighted rollers. The testimony from the trial shows that ARCI
    viewed the statement on RapidGRIP’s label about using a weighted roller as a
    recommendation, not as a requirement. Given the label and the testimony in the
    record, the trial court could have reasonably concluded that the use of weighed
    rollers was not required by the label, or that ARCI’s failure to use a weighted roller
    did not play a substantial role in causing the RapidGRIP to fail.
    20
    ARCI also disputed U.S. Ply’s claim that it installed the RapidGRIP under
    weather conditions inconsistent with RapidGRIP’s label. During trial, ARCI relied
    on weather records to establish what the ambient air temperatures were when it
    installed the rolls of RapidGRIP at Sunningdale. The weather records in evidence
    cover the months of January through March 2013. The temperatures recorded are
    based on temperatures measured at an airport about 16 miles from Sunningdale.
    Based on these records, Jody testified that ARCI never installed the RapidGRIP
    when the ambient air temperatures were below 50℉ or when the rolls were not at
    least 70℉. Jody’s son, Marshall Born, also addressed whether ARCI installed the
    RapidGRIP under conditions inconsistent with those on the product’s label. Marshall
    was ARCI’s construction supervisor for ARCI’s project at Sunningdale. He testified
    that ARCI’s job foremen were familiar with the temperatures in which RapidGRIP
    should be installed. Marshall testified that ARCI’s crews did not “work or install
    anything under those temperatures.” Victor Robles, the ARCI foreman who
    supervised the crew that built the roof on building two, also testified in the trial.
    According to Victor, his crew installed the RapidGRIP when the air was at least 70℉
    on the roof. 25 Hughes and Jody testified that the temperatures on a building’s roof is
    25
    The ARCI foreman in charge of installing the roof on apartment building
    one, Toro Mendoza, did not testify in the trial. Marshall explained that he had known
    Mendoza for over twenty years, that Mendoza left ARCI shortly after he finished
    21
    typically around 25% higher than the temperature when measured from the ground.
    We conclude the record contains conflicting evidence about whether ARCI installed
    the RapidGRIP at temperatures outside the temperatures found on the product’s
    label. Nevertheless, the great weight and preponderance of the evidence does not
    show that ARCI installed the RapidGRIP when it was less than 50℉ as claimed by
    U.S. Ply.
    U.S. Ply also points to testimony and other evidence before the trial court that
    is critical of ARCI’s workmanship. It relies on this evidence to support its claim that
    the tests on the leftover roll were unreliable or that they the trial court gave the tests
    entirely too much weight. U.S. Ply’s brief, however, fails to address the evidence in
    the record that contradicts the evidence on which it relies. The record includes
    testimony disputing U.S. Ply’s claim that ARCI failed to properly store U.S. Ply’s
    roofing materials before installing them on the roofs. For example, Victor testified
    that during the construction process, ARCI stored and covered the RapidGRIP inside
    a garage at night. The instructions accompanying RapidGRIP state the product “must
    be covered and not left exposed for more than 90 days.” There is no evidence in the
    record showing that ARCI exposed the RapidGRIP to the weather or to the effects
    working on building one at Sunningdale, and that Mendoza left because he had
    “personal legal issues” and “personal stuff going on.”
    22
    of the sun for ninety days, and no evidence that the product was left exposed to any
    extreme heat or cold. Generally, the testimony before the trial court shows that when
    using the RapidGRIP, ARCI’s crews took the rolls out of the boxes they came in
    shortly before laying one or more rolls out on the roof where those rolls were to be
    installed. After removing a roll from a box, members of ARCI’s crew laid the roll
    out to allow it to warm for a short period of time, less than an hour, before installing
    it over the bottom ply on the modified-bitumen roofs.
    The record also contains evidence disputing U.S. Ply’s claims that various
    issues with ARCI’s workmanship explained why the RapidGRIP failed. ARCI’s
    roofing expert, Hughes, explained that all but one of the deficiencies Hoecherl
    pointed out in his February 2013 report could be explained by the fact Hoecherl
    inspected the roofs before ARCI finished them. Hughes characterized most of the
    items Hoecherl criticized about the roofs as consisting of incomplete work, not poor
    workmanship. According to Hughes, ARCI’s work at Sunningdale “met the standard
    of care and responsibilities for a roofing contractor within the industry.”
    Marshall also address whether ARCI left its work in progress under conditions
    that allowed moisture to penetrate the roofs. According to Marshall, ARCI did not
    leave the roofs overnight without first sealing the roofs’ seams. While Marshall
    acknowledged that Hoecherl’s photos show some areas where the roofs’ seams were
    23
    not sealed, there is no testimony from any of U.S. Ply’s experts showing that
    moisture penetrated the RapidGRIP and caused the RapidGRIP’s failure in these
    areas or any others. Instead, the testimony of U.S. Ply’s witnesses suggests that the
    penetration of the RapidGRIP membrane with moisture could explain why the
    RapidGRIP failed. The evidence before the trial court shows that ARCI presented
    evidence disputing U.S. Ply’s theory that the presence of moisture below the
    RapidGRIP explained why the RapidGRIP failed. Jody testified that when Hoecherl
    was looking at the roofs, Hoecherl never told him that he found a place where
    moisture had penetrated the roof. Additionally, Jody testified that none of the people
    who inspected the roofs told him that the RapidGRIP failed because water penetrated
    the RapidGRIP on the roofs. In his testimony, Hoecherl agreed that he never saw
    any evidence where water migrated below the RapidGRIP.26 Under the
    26
    We note that Hoecherl stated that the absence of moisture does not show
    that no water entered the roof because water evaporates. Yet Hoecherl couched his
    testimony as problems that “could cause” a roof to fail and he never stated that, in
    his opinion, water penetrated the roofs and explained why the RapidGRIP
    malfunctioned. A letter that BES sent to the owner’s architect in late-May 2013,
    which was signed by Jerry Abendroth, who is the partner in charge of the
    investigation BES was hired to do at Sunningdale, states that “[s]ince BES was not
    involved during the installation of the roof system, we are unable to definitively
    determine the cause or extent of the un-adhered roof membrane.” This letter was
    also admitted into evidence during the trial.
    24
    circumstances, the trial court could have concluded that water penetration either did
    not occur or was not a substantial cause for the RapidGRIP’s malfunction.
    We conclude the record contains conflicting evidence about whether ARCI’s
    storage, workmanship, or installation errors caused the roofs to fail.27 In a case tried
    to the bench, the trial court acts as the factfinder and determines what testimony it
    finds credible.28 It also weighs the relevant evidence when resolving the contested
    issues of fact in a trial. 29 On this record, we conclude the trial court could have
    reasonably rejected U.S. Ply’s claims that the RapidGRIP malfunctioned because
    ARCI failed to store or install it properly. We further conclude that legally and
    factually sufficient evidence supports the trial court’s findings on ARCI’s breach of
    express warranty claims. Because we have found the record supports the trial court’s
    verdict on ARCI’s breach of express warranty claims, we need not address whether

    Keller, 168 S.W.3d at 814

    sufficiency review, the appellate court cannot disregard evidence that would allow

    evidence also supports the judgment on its breach of implied warranty and DTPA
    claims. 30 For these reasons, we overrule U.S. Ply’s first, sixth, and seventh issues.
    Damages
    In issue eight, U.S. Ply argues the evidence does not support the trial court’s
    conclusion that ARCI was entitled to damages for replacing the roof on building
    one. 31 According to U.S. Ply, because it was willing to guarantee the original roof
    on building one, the expenses ARCI incurred to replace it were unnecessary. In
    response, ARCI argues it did not replace the roof on building one, but instead
    repaired the roof by adding additional layers of roofing material over it based on the
    repair method recommended to the project’s owner by BES.
    The evidence admitted in the trial shows that BES, who was hired by
    Sunningdale’s architect, recommended that ARCI repair the roof on building one by
    “[overlaying it] with a new two-ply modified bitumen roof system.” 32 Steve Kratky,
    30
    See Tex. R. App. P. 47.1.
    31
    In its appeal, ARCI has not disputed the damages the trial court awarded to
    compensate ARCI for repairing the roof on building two. In closing argument, U.S.
    Ply’s attorney conceded that U.S. Ply owed ARCI for those repairs.
    32
    The recommendation to use an overlay repair on the roof came from Kevin
    Palma and Jerry Abendroth. Abendroth testified in the trial that he helped start BES,
    and the letter he signed shows that he was the project manager for BES for the
    evaluation the company did on the roofs at Sunningdale.
    26
    a Construction Supervisors’ employee, was involved in the discussions that occurred
    between ARCI and Construction Supervisors about the repairs needed on building
    one. During the trial, Kratky testified that ARCI repaired that roof by overlaying the
    existing roof system with other plies of material that are used to build modified-
    bitumen roofs. While U.S. Ply misstates the evidence in claiming the roof was
    replaced, we nonetheless understand its argument to assert that the cost ARCI
    incurred to repair the roof on building one was unnecessary because U.S. Ply was
    willing to guarantee it despite the problems BES and ARCI observed with the roof
    ARCI installed on building one.33
    The premise of U.S. Ply’s argument is that ARCI acted unreasonably by
    rejecting its offer to issue a guarantee on the roof. The language in a sample
    guarantee issued by U.S. Ply for roofs is among the exhibits admitted in the trial. Its
    terms are relevant to evaluating whether ARCI acted reasonably when it rejected
    U.S. Ply’s offer to guarantee the roof on building one. The terms of U.S. Ply’s
    guarantee reveal that the guarantee, had one been issued, would have covered only
    nine designated risks relevant to problems with roofs while excluding eleven others.
    33
    See Perry v. Cohen, 
    272 S.W.3d 585
    , 587 (Tex. 2008) (“Appellate briefs
    are to be construed reasonably, yet liberally, so that the right to appellate review is
    not lost by waiver.”).
    27
    Additionally, the terms of the guarantee extend only to the roof’s “original owner.”
    There is no testimony in the record showing that Sunningdale’s owner agreed to
    accept U.S. Ply’s offer. Thus, the guarantee, even had ARCI agreed to it, would not
    have protected ARCI from the claims that it breached its subcontract with
    Construction Supervisors by building a roof that did not fully comply with it contract
    with Construction Supervisors.
    The fact the proposed guarantee would include exclusions while covering
    only certain risks further supports the trial court’s implied finding that ARCI did not
    act unreasonably when it rejected U.S. Ply’s proposal to accept the guarantee in lieu
    of filing suit. Under Texas law, a plaintiff is duty-bound to mitigate any damages it
    may suffer, but the plaintiff need not sacrifice its own contract rights in doing so.34
    We note that when the defendant claims the plaintiff failed to mitigate damages, the
    defendant bears the burden of proving that claim. 35 On this record, as a reasonable
    finder of fact, the trial court could have decided that U.S. Ply failed to carry its

    & CRAIG SMYSER, TEXAS PRACTICE: CONTRACT LAW § 10.6 (last updated Sept.
    2018). We note that U.S. Ply’s pleadings include a claim that ARCI failed to
    reasonably mitigate its damages.

    28
    burden in proving that ARCI acted unreasonably by rejecting the proposed
    guarantee. 36 We overrule U.S. Ply’s eighth issue.
    2. Did ARCI’s alleged failure to follow U.S. Ply’s instructions
    and industry standards when installing the RapidGRIP waive
    its right to recover on its warranty claims?
    In issue nine, U.S. Ply argues that by installing the RapidGRIP incorrectly,
    ARCI voided any warranties that might apply to installing the roof on building one.
    Even when we construe U.S. Ply’s argument liberally, however, U.S. Ply’s argument
    relies on ARCI’s conduct as the basis for any waiver. U.S. Ply does not rely on any
    waiver language on the product’s label or other information that U.S. Ply provided
    ARCI in support of issue nine.37
    Under Texas law, a plaintiff’s conduct is not a defense to a breach-of-warranty
    action. 38 Instead, the plaintiff’s conduct, including any claims alleging the plaintiff
    36
    See Dow Chem. Co. v. Francis, 
    46 S.W.3d 237
    , 241 (Tex. 2001) (explaining
    that the “matter of law” legal-sufficiency standard applies when the factfinder’s
    adverse finding is one on which the party bore the burden of proof).

    but liberally); see also Tex. Bus. & Com. Code Ann. § 2.313(a)(2) (indicating that
    the manufacturer’s description of its goods creates an express warranty when the
    description forms a basis of the parties’ bargain).

    See Signal Oil & Gas Co. v. Universal Oil Prods.,

    the consequential damages caused by the breach of implied warranty”); Indust-Ri-

    installed the product incorrectly, are matters that are relevant to whether the product
    caused the plaintiff’s damages.39 We have already explained that the evidence
    allowed the trial court to conclude that ARCI did not materially violate the
    instructions that apply to installing the RapidGRIP in resolving issues one, six,
    seven, and eight. 40 For those same reasons, we reject the arguments that U.S. Ply
    uses to support issue nine.
    In this case, the record contains conflicting testimony and evidence about
    whether ARCI installed RapidGRIP correctly and whether it applied the product in
    a manner consistent with the product’s instructions and industry standards. In bench
    trials, the trial court determines the weight to give any testimony and resolves
    conflicts and inconsistencies in the testimony. 41 The evidence allowed the trial court
    to conclude that the RapidGRIP malfunctioned even though ARCI stored and
    installed it properly. We overrule U.S. Ply’s ninth issue.

    3. Was the testimony of Bradley Hughes, ARCI’s roofing expert,
    properly admitted and does it provide reliable support for the verdict?
    In issues two through five, U.S. Ply argues that Hughes’ testimony was
    inadmissible for four reasons: (1) ARCI did not name him by the stated deadlines in
    the trial court’s docket-control order; (2) he was not qualified by virtue of his training
    or experience to express opinions about RapidGRIP; (3) he was not qualified to
    express opinions about what caused the RapidGRIP to fail; and (4) his opinions were
    speculative because they did not have a sufficient foundation. We address these
    arguments in order.
    Before trial, the trial court held a hearing to consider U.S. Ply’s objections
    claiming that Hughes should not be allowed to testify in the case. In the hearing,
    U.S. Ply argued that the trial court should strike Hughes as a witness because ARCI
    failed to comply with the docket-control order controlling the discovery deadlines
    that applied to the case. During the hearing, ARCI argued the order required ARCI
    to produce Hughes’ report no later than by mid-June 2016, and that it produced his
    report in late-January 2016, well before that docket-control order’s deadline. When
    ruling on U.S. Ply’s motion, the trial court advised the parties the court had decided
    to deny the motion.42
    42
    The clerk’s record contains an order granting U.S. Ply’s motion to exclude
    Hughes as a witness, but the order contradicts the ruling the trial court made before
    31
    The record shows the trial court allowed Hughes to testify in the trial. 43 In
    late-May 2015, ARCI designated Hughes as an expert but did not produce his report.
    In late-January 2016, ARCI amended its designation of experts and produced a
    report, signed by Hughes. In an amended docket-control order, signed in late-March
    2016, the trial court signed a new docket-control order, ordering discovery to
    conclude by September 12, 2016. The amended order does not specify the date by
    which the parties were to produce reports from their experts. Instead, the amended
    order provides: “If no date or limitation on discovery is given below, the item is
    governed by the Texas Rules of Civil Procedure.”
    Given this language, we look to the rules in the Texas Rules of Civil Procedure
    to determine whether ARCI violated the docket-control order that applies to
    resolving U.S. Ply’s complaint that the trial court failed to enforce the deadlines that
    the trial began. U.S. Ply does not rely on the signed order in its brief. Nevertheless,
    the hearing shows the trial court intended to sign an order overruling U.S. Ply’s
    motion as the trial court stated that it would “allow the testimony of Mr. Hughes and
    overrule the objections of U.S. Ply. So I’m signing that order now.” We conclude
    the trial court signed the order granting U.S. Ply’s motion by mistake.
    43
    During the hearing, U.S. Ply complained that ARCI failed to designate
    Hughes until March 2015 and that ARCI did not immediately produce his report at
    that time along with all information he relied on to form his opinions. After
    presenting the court with these complaints, U.S. Ply’s attorney advised the court that
    Hughes should be excluded because he “was not timely designated as an expert[.]”
    32
    apply to Hughes’ report. Under the Rules, ARCI needed to provide U.S. Ply with
    Hughes’ report at least ninety days before September 12, 2016, the date on which
    the discovery period ended.44 Thus, ARCI was required to produce Hughes’ report
    by mid-June 2016. 45 The record shows that ARCI designated and produced Hughes’
    report more than four months before that deadline. We conclude the trial court
    properly rejected U.S. Ply’s argument that ARCI failed to produce Hughes’ report
    by the required deadline. We overrule U.S. Ply’s second issue.
    In issues three and four, U.S. Ply argues that Hughes lacked the qualifications
    needed to express reliable opinions explaining why the roofs installed at
    Sunningdale failed. In issue five, U.S. Ply contends Hughes based his opinions on
    unreliable tests performed on the leftover roll. According to U.S. Ply, the evidence
    shows that the leftover roll could not be subjected to testing capable of yielding
    reliable results because it was not in the condition it was in when it was delivered to
    Sunningdale. U.S. Ply concludes that because Hughes based his opinions almost
    44
    See Tex. R. Civ. P. 195.2(a) (providing that unless the trial court orders
    otherwise, the parties must furnish the information required under Rule 194.2(f) 90
    days before the end of the discovery period); 
    id. 194.2(f) (providing
    that upon
    request, the party from whom disclosure has been requested must disclose
    information about the identity and the substance of the witnesses the responding
    party retained to testify as experts).
    45
    
    Id. 33 entirely
    on the tests done on the leftover roll, his opinions are without foundation,
    making them speculative and unreliable.
    An abuse-of-discretion standard applies to an appellate court’s review of a
    trial court’s decision admitting expert testimony. 46 Courts determine whether
    evidence is reliable from all the evidence.47 Expert testimony is admissible when (1)
    the expert is qualified, and (2) the testimony is relevant and based on a reliable
    foundation.48 “‘If scientific, technical, or other specialized knowledge will assist the
    trier of fact to understand the evidence or to determine a fact in issue, a witness
    qualified as an expert by knowledge, skill, experience, training, or education may
    testify thereto in the form of an opinion or otherwise.’” 49 “‘If the expert’s scientific
    evidence is not reliable, it is not evidence.’” 50 If the opinion the expert expressed at
    trial “is based on assumed facts that vary materially from the actual, undisputed facts,

    the opinion is without probative value and cannot support a verdict or judgment.”51
    That said, courts do not determine whether an expert’s opinion is reliable by deciding
    whether the expert’s opinion appears to be correct.52 Rather, the factors courts use
    when determining if the expert’s opinions are reliable look to the reliability of the
    method and analysis the expert used in forming the opinions the expert expressed in
    the trial.53
    The qualifications Hughes possessed as a roofing expert are primarily those
    that are in his resume. Hughes’ resume shows that he is licensed in the State of
    California as a general contractor and as a roofing contractor. He has more than thirty
    years of experience in the construction industry, and his experience includes
    supervising the construction of composite shingle, built-up, and other types of roofs
    that are installed on apartments, condominiums, and commercial buildings. Hughes’
    testimony shows that he also has experience with installing modified-bitumen roofs.
    Hughes also described his experience in the roofing industry when he testified.
    During the trial, Hughes testified that for the past eighteen years he has worked for

    Id. 35 Bert
    Howe & Associates. According to Hughes, his day-to-day work for Bert Howe
    involves inspecting roofs, writing reports about his findings, analyzing the
    performance of roofs, and writing specifications for repairs, when required. Hughes
    testified that in the past eighteen years, he has inspected over 20,000 roofs. Hughes
    explained that before working for Bert Howe, he worked more than twenty years
    “within the roofing industry as a tradesman installing, repairing, [and] rehabilitating
    roofing systems . . . , which are inherent to modified bitumen applications such as
    [the] case [before the court.]” He explained that his experience installing roofs
    includes installing the type of modified-bitumen systems used at Sunningdale. He
    has also inspected modified-bitumen roofs in his work with Bert Howe, including
    taking samples from the existing roof and having those samples tested. Although
    Hughes represented that he had a great deal of experience with roofs, he also agreed
    that he was not a scientist, a chemist, or certified to conduct tests on roofing material,
    which is work done by labs.
    Hughes’ testimony reveals that he reviewed twelve categories of material
    while investigating the failure of the RapidGRIP used at Sunningdale. He did not
    inspect the roofs because they were repaired before he was hired. The information
    he reviewed included the instructions issued by U.S. Ply about RapidGRIP and how
    it is installed. He also reviewed testing and materials standards referenced on
    36
    RapidGRIP’s label, industry standards for installing low-sloped-asphalt roofs,
    construction records associated with ARCI’s work, weather records for the days
    ARCI installed the RapidGRIP, construction and inspection photographs taken of
    the roofs, and reports issued by BES about its observations and findings on the roofs.
    Hughes agreed that he relied heavily on U.S. Ply’s and Mid-States Asphalt’s testing
    of the leftover roll when reaching the opinions he expressed at trial. 54 He also agreed
    he has no experience in designing asphalt-roofing products, that he did not have an
    independent lab perform tests on any samples taken from Sunningdale’s roofs, and
    that he is not a chemist. Hughes stated that he is qualified to express opinions about
    the performance of self-adhering membranes that contractors install on roofs from
    the perspective of a roofing consultant, inspector, and contractor.
    As we understand Hughes’ testimony, Hughes thought that the RapidGRIP
    ARCI used on the project failed to perform as a high tack, self-adhering membrane
    that could be applied without using supplemental heat. He also expressed the opinion
    that any errors ARCI made when installing the roofs did not contribute to causing
    the RapidGRIP ARCI installed to fail.
    54
    Hughes stated that he understood the leftover roll had been stored properly
    before U.S. Ply and Mid-States Asphalt tested it. He also agreed that he had no
    personal knowledge about how the roll was stored to protect it from the elements
    before anyone tested it. Hughes acknowledged that the adhesive qualities of the roll
    could degrade if the roll was not stored properly.
    37
    U.S Ply contends the trial court should not have found that Hughes was
    qualified to testify as an expert. It argues that ARCI failed to show that Hughes had
    experience or expertise in manufacturing, designing, or marketing RapidGRIP. That
    said, ARCI sought to prove that the RapidGRIP malfunctioned because the
    RapidGRIP it purchased did not have the qualities represented on the label even
    when applied in a manner consistent with industry practices and the instructions on
    the product’s label. Hughes did not testify the formula U.S. Ply used for RapidGRIP
    was incapable of producing a membrane consistent with the qualities stated on the
    label. Essentially, Hughes’ testimony shows that he thought the problem with the
    RapidGRIP ARCI acquired occurred before they were delivered to Sunningdale
    because ARCI stored the rolls properly, installed the rolls properly, and that
    nonetheless, the RapidGRIP failed on both roofs.
    As to the trial court’s decision to allow Hughes to testify as a roofing expert,
    the record shows that Hughes has much more expertise evaluating roofs, including
    the type of roofs at issue here, than an ordinary factfinder. He has also evaluated
    many problems with roofs, and in his job, companies rely on him to determine why
    roofs fail and how they should be fixed. Under the Texas Rules of Evidence,
    opinions offered by witnesses who have “technical[] or other specialized
    knowledge” are admissible if the opinion assists the factfinder in deciding the issues
    38
    in dispute.55 Had ARCI claimed the formula U.S. Ply used to create RapidGRIP
    would not produce a high-tack, self-adhering membrane, a scientist or
    manufacturing witness familiar with the manufacture of roofing membranes might
    have been an important witness for that trial. That was not, however, the theory
    ARCI advanced in this trial. Instead, ARCI sought to prove the RapidGRIP that it
    purchased malfunctioned in ways that were not consistent with the qualities stated
    on the product’s label.
    Given Hughes’ experience in the roofing industry, we conclude the trial court
    could reasonably have found him qualified to express opinions about whether the
    product malfunctioned. 56 While Hughes had no formal training in manufacturing or
    designing roof membranes, experts need not always be formally trained to possess
    information that is helpful to triers of fact. For instance, in discussing qualifications
    of experts, the Texas Supreme Court explained that an “experienced car mechanic’s
    diagnosis of problems with a car’s performance may well be relevant and reliable
    without resort to engineering principles.”57

    56
    See 
    Gammill, 972 S.W.2d at 722
    (noting that “there are many instances
    when the relevance and reliability of an expert witness’s testimony are shown by the
    witness’s skill and experience”).
    57
    
    Id. 39 The
    trial court’s conclusion that Hughes followed a proper methodology to
    arrive at his opinions is also reasonable and supported by the record. Hughes’
    testimony reveals he is familiar with industry practices for installing modified-
    bitumen roofs. His testimony shows that he is familiar with the manner and
    conditions under which products like RapidGRIP are used. His testimony shows that
    he considered whether the product was stored or installed improperly and that he
    considered the test results on the leftover roll. His conclusion that the RapidGRIP
    malfunctioned as a self-adhering membrane at the temperatures it which it was
    installed represents a reasoned opinion reached after considering the available
    evidence. We conclude that Hughes was qualified to express the opinions he
    expressed that U.S. Ply has challenged in the appeal. We overrule issue three.
    In issues four and five, U.S. Ply criticizes the methodology Hughes followed
    in arriving at his opinions. According to U.S. Ply, Hughes ignored uncontroverted
    testimony showing that the leftover roll was not in the same condition it was in when
    it was delivered to Sunningdale. Also, U.S. Ply suggests that the methodology
    Hughes should have followed required him to submit samples of the RapidGRIP to
    an independent lab. According to U.S. Ply, testing by an independent lab is normally
    performed to determine what caused a roof to fail. U.S. Ply concludes that errors in
    Hughes’ methodology makes his opinions speculative and unreliable.
    40
    The Texas Rules of Evidence allow experts to base opinions “on facts or data
    in the case that the expert has been made aware of, reviewed, or personally
    observed.”58 The testimony about how the leftover roll was stored before U.S. Ply
    and Mid-States Asphalt tested it was largely circumstantial. There is, however, direct
    testimony showing that Marshall acquired the leftover roll from ARCI employees
    who took it from one of the roofs at Sunningdale. When the partial roll arrived at
    ARCI’s offices, it was not in a box. There is, however, testimony showing that U.S.
    Ply sent the leftover roll to Mid-States Asphalt in a box. Other than this testimony,
    the evidence is circumstantial about whether ARCI stored the leftover roll properly
    before ARCI’s employees gave it to Marshall. That said, the testimony does not
    show the leftover roll was ever exposed to extreme cold or heat or that the leftover
    roll was exposed to weather, including sunlight, for more than 90 days before the
    leftover roll was tested.
    There is also no testimony showing that Mid-States Asphalt considered its
    tests unreliable, that Mid-States Asphalt considered its testing insufficient without
    further testing by an independent lab, or that the leftover roll could not be tested to
    determine whether the RapidGRIP ARCI purchased could be applied without using
    a torch. The fact that Mid-States Asphalt offered to replace the product after
    58
    Tex. R. Evid. 703.
    41
    completing its tests is circumstantial evidence supporting the trial court’s inference
    that Mid-States Asphalt concluded the roll did not have the qualities of tackiness
    stated on the product’s label. Based on the direct and circumstantial evidence, and
    because the product’s label states that the product should not be “left exposed for
    more than 90 days[,]” the trial court could have reasonably rejected U.S. Ply’s
    arguments that U.S. Ply’s and Mid-States Asphalt’s tests were not reliable or
    relevant to proving what condition the rolls were in when ARCI acquired them.
    Next, we turn to U.S. Ply’s claim that Hughes’ opinions were unreliable
    because he failed to have samples of the RapidGRIP tested by an independent lab.
    There is no testimony in the record showing what constitutes a normal investigation
    when evaluating what caused a modified-bitumen roof (or any other type of roof) to
    fail. There is also nothing in the record showing that the proper methodology for
    determining the cause of a roof’s failure requires testing beyond the testing done by
    the entities that manufactured and sold the roofing products used in building the roof.
    Mid-States Asphalt and U.S. Ply both relied on their testing to extend remedies for
    the RapidGRIP’s failure without submitting the leftover roll or other samples of the
    RapidGRIP for further testing by an independent lab. Moreover, before extending
    their respective offers, neither U.S. Ply, nor Mid-States Asphalt, suggested that more
    testing was needed by an independent lab.
    42
    Finally, the opinions Hughes expressed are supported by testimony that is in
    the record explaining how ARCI built the roofs. ARCI has a long track record of
    successfully building modified-bitumen roofs using membranes like RapidGRIP.
    The tests on the leftover roll were done before the useful life for the product, as
    shown on the product’s label, expired. This factor also tends to support the trial
    court’s implied findings. While the record contains conflicting evidence about how
    ARCI stored and installed the roofing materials before it used them, Hughes was
    entitled to assume that ARCI stored and installed the RapidGRIP properly when
    forming his opinions given the evidence presented in the trial. We conclude the trial
    court did not rely entirely on Hughes’ credentials when it found Hughes gave
    credible and reliable testimony in the trial.
    To summarize our conclusions, Hughes’ opinions were not speculative,
    conclusory, or without a sufficient foundation to tie his opinions to the relevant facts
    of the case. We hold the trial court did not err by exercising its discretion to allow
    Hughes to testify or by finding that he gave credible and reliable opinions during the
    trial. We overrule issues four and five.
    4. Did U.S. Ply preserve its right to obtain the trial
    court’s written findings to explain its verdict?
    In issue ten, U.S. Ply asserts that given U.S. Ply’s request for findings, the
    trial court erred by failing to provide the parties with written findings of fact and
    43
    conclusions of law. The record shows that U.S. Ply filed its request for findings
    within twenty days of the date the trial court signed the judgment. We conclude that
    U.S. Ply’s initial request for findings was timely. 59 Even so, U.S. Ply then failed to
    file a notice of past due findings. A notice of past due findings is required when a
    trial court has failed to comply with a party’s initial request for written findings.60 If
    a party fails to file a notice of past due findings, it can no longer complain of the trial
    court’s failure to provide the parties with written findings. 61 We conclude that U.S.
    Ply waived its right to complain about the trial court’s failure to reduce its findings
    to writing. We overrule U.S. Ply’s tenth issue.
    Conclusion
    Having carefully considered each of U.S. Ply’s issues, we affirm the trial
    court’s judgment.
    AFFIRMED.
