Before COLLOTON, WOLLMAN, and BENTON, Circuit Judges
                       ____________

WOLLMAN, Circuit Judge.

      The City of Iowa City, Iowa (the City) hired general contractor Joseph J.
Henderson & Sons, Incorporated (Henderson) to design and install a bio-solids
building as a part of a project meant to improve and expand the City’s wastewater
treatment facility. Panels on the building’s roof were damaged during a windstorm.
Henderson filed a claim with Travelers Property Casualty Insurance Company of
America (Travelers), asserting that Travelers was required to cover the roof’s damage
pursuant to the City’s builder’s risk insurance policy (the Policy) with Travelers.
Travelers responded that it was not liable under the Policy because the damage was
caused in whole or in part by Henderson’s faulty workmanship. Henderson’s claim
having been denied, the case ultimately went to trial, during which a jury found for
Henderson and awarded $581,235.65 in damages, which included a $142,927.43
award for fees related to the engineering investigation regarding the cause of the
failure. Travelers appeals the district court’s1 denial of its motion for judgment as a
matter of law and, in the alternative, moves for a new trial or remittitur. We affirm.

                                          I.

      The Policy identifies Henderson as a “named insured” and generally provides
that Travelers will “pay for direct physical loss of or damage to Covered Property
from any of the Covered Causes of Loss.” The Policy defines “Covered Causes of
Loss” to include “RISKS OF DIRECT PHYSICAL LOSS OR DAMAGE except
those causes of loss listed in the Exclusions.” Travelers does not contest that a
windstorm constitutes a risk of direct physical loss or damage.

      The Policy contains three exclusions, two of which are relevant here: the
“external event” exclusion and “faulty workmanship” exclusion. The external event
exclusion provides that Travelers “will not pay for loss or damage caused directly or
indirectly by” governmental action, nuclear hazard, war and military action,
ordinance of law, collapse or imminent collapse from flood or earth movement, or
fungus and rot. The policy makes clear that any “loss or damage” stemming from
these events “is excluded regardless of any other cause or event that contributes
concurrently or in any sequence to the loss or damage.” Under Iowa law, this

exclusionary language aimed at concurrent causes is referred to as an “anticoncurrent-
cause provision.” See W. Liberty v. Emp’rs Mut. Cas. Co., 

, 880 n.1
(Iowa 2019) (“An anticoncurrent-cause provision bars recovery based on an excluded
event even if another event could be considered a concurrent cause of the same
loss.”). The faulty workmanship exclusion states that Travelers “will not pay for loss
or damage caused by or resulting from . . . [o]mission in, or faulty, inadequate or
defective: (1) [p]lanning, zoning, development, surveying, siting, design or
specifications; or (2) [m]aterials, workmanship or maintenance.” Importantly, this
exclusion contains no language akin to the anticoncurrent-cause provision found in
the external event exclusion. To the contrary, the policy states that the faulty
workmanship exclusion does not apply “if loss or damage by a Covered Cause of
Loss results.”

       Henderson, Iowa City, and Travelers each hired different engineering firms to
determine why certain roof panels of the bio-solids building were damaged. The
engineering firms arrived at differing conclusions that the wind, faulty workmanship,
or potentially some combination of the two caused that damage. When the case
proceeded to trial, the jury heard conflicting evidence regarding the respective roles
that wind and faulty workmanship played in damaging the building’s roof. Travelers
moved for judgment as a matter of law after Henderson’s case-in-chief and its own,
asserting that no evidence had been presented to show that the windstorm could have
caused damage absent the construction defects. The district court denied both
motions and submitted the case to the jury. After the jury found in favor of
Henderson, Travelers renewed its motion for judgment as a matter of law and, in the
alternative, moved for a new trial or remittitur, see Fed. R. Civ. P. 50(b), 59, which,
as mentioned above, the district court denied.

diversity action. Accordingly, “we must endeavor to decide the case as the Iowa
Supreme Court would decide it” and “are bound by the decisions of the Iowa
Supreme Court.” Doe v. Baxter Healthcare Corp., 

, 407 (8th Cir. 2004).

A. Denial of Motion for Judgment as a Matter of Law

       Travelers advances several theories why the Policy’s faulty workmanship
exclusion relieves it of liability as a matter of law. Under Iowa law, “[t]o determine
if an insurance policy affords coverage under a particular set of circumstances,
[courts] generally look first to the insuring agreement, then to the exclusions and the
exceptions to the exclusions.” Nat’l Sur. Corp. v. Westlake Invs., LLC, 

, 739 (Iowa 2016). The insurer has a “duty to define any limitations or
exclusionary clauses in clear and explicit terms.” Postell v. Am. Family Mut. Ins.
Co., 

, 41 (Iowa 2012) (quoting Allied Mut. Ins. Co. v. Costello, 

, 286 (Iowa 1996)). Consequently, courts are obligated to strictly
construe policy exclusions against the insurer. See

       Travelers first argues that the faulty workmanship exclusion contains an
anticoncurrent-cause provision, which, as earlier discussed, bars recovery when the
loss is caused by both an excluded event (faulty workmanship) and an event that
would otherwise be covered under the policy (windstorm). See West 

n.1. We conclude that the faulty workmanship exclusion does not
include an anticoncurrent-cause provision.

      The faulty workmanship exclusion states that Travelers “will not pay for loss
or damage caused by or resulting from [faulty workmanship],” and immediately

                                         -4-
clarifies that “if loss or damage by a Covered Cause of Loss [e.g., a windstorm]
results, [Travelers] will pay for that resulting loss or damage.” We construe this
language to mean that Travelers will not pay for damage caused by faulty
workmanship, except when the damage is caused in part by a covered event, such as
a windstorm. Cf. Tento Int’l, Inc. v. State Farm Fire & Cas. Co., 

, 663
(9th Cir. 2000) (holding that similar contract language was a “resulting-loss
provision”). This construction is especially appropriate when the faulty workmanship
exclusion is viewed in context. Unlike the faulty workmanship exclusion, the
external event exclusion includes an explicit anticoncurrent-cause provision, stating
that Travelers “will not pay for loss or damage caused directly or indirectly by
[external events] . . . regardless of any other cause or event that contributes
concurrently or in any sequence to the loss or damage.” J.A. 2068 (emphasis added).
If Travelers intended that the faulty workmanship exclusion applied regardless of any
concurrent causes, it could have adopted express language similar to the external
event exclusion. Iowa courts “‘will not write a new contract of insurance’ for the
parties” when an insurance policy and its exclusions are clear. Boelman v. Grinnell
Mut. Reins. Co., 

, 502 (Iowa 2013) (quoting Thomas v. Progressive
Cas. Ins. Co., 

, 682 (Iowa 2008)). We decline to do so here. See also
Kalell v. Mut. Fire & Auto. Ins. Co., 

, 868 (Iowa 1991) (“If [insurer]
intended to exclude coverage of an incident simply because it involved [an excluded
cause of loss], it was incumbent on it to say so in its policy.”).

       Travelers relies heavily on Amish Connection, Inc. v. State Farm Fire &
Casualty Co., 

(Iowa 2015), which we conclude does not apply to the
facts of this case. There, a corroded drainpipe burst during a rainstorm, resulting in
a claim by the insured that the water damage was covered by its insurance policy.
The policy contained two exclusions, under which the insurer was not liable if either
applied.

(“We insure for accidental direct physical loss to property covered
under this policy unless the loss is: 1. limited in the PROPERTY SUBJECT TO
LIMITATIONS section; or 2. excluded in the LOSSES NOT INSURED section”

                                         -5-
(emphasis in original)). The first exclusion stated that the insurer was not liable for
losses “caused by rain,” except in certain circumstances not relevant here.

The second exclusion provided that the insurer was not liable if the damage was
caused by certain events—like “rust” and “corrosion”—but included a clause stating
that the exclusion did not apply if the damage was caused by “Specified Causes of
Loss,” which included “water damage” from the “breaking or cracking of any part of
a system . . . containing water.”

The insured argued, in part, that even if
the first exclusion applied since the corroded drainpipe burst during a rainstorm, the
policy nevertheless covered the resulting damage because the insured’s damage was
covered under the exception to the second exclusion: the insured suffered “water
damage” due to the “breaking . . . of . . . a system . . . containing water,” or the
drainpipe.

The Iowa Supreme Court rejected this argument, noting that
the first exclusion “effectively ha[d] an anticoncurrent-cause provision,” since, unlike
the second exclusion, it contained no express exception for “Specified Causes of
Loss,” and only one of the exclusions had to apply to preclude coverage.

240 (stating that the exception to the second exclusion does “not create coverage for
rain damage because an exception to an exclusion does not create coverage that
otherwise is lacking. . . . Unlike the [second exclusion], the [first exclusion pertaining
to rain] contains no exception for ‘Specified Causes of Loss.’”). Thus, “the rain
limitation control[led] regardless of whether the breaking drainpipe is considered a
concurrent cause of the rainwater damage.”

. Here, unlike in Amish
Connection, the faulty workmanship exclusion does contain an express exception for
damages “if loss or damage by a Covered Cause of Loss [e.g., a windstorm] results.”
The faulty workmanship exclusion thus contains no anticoncurrent-cause provision,
and we decline to read it as though it does.




                                           -6-
        Travelers next argues that even if the faulty workmanship exclusion lacks an
anticoncurrent-cause provision, coverage is nevertheless excluded because faulty
workmanship was the sole proximate cause or the efficient proximate cause of loss.2
“When insurance policies lack . . . an anticoncurrent-cause provision, we have held
an accident that has two independent causes, one of which is covered and one
excluded, is covered unless the excluded cause is the sole proximate cause of injury.”

(citing Grinnell Mut. Reins. Co. v. Emp’rs Mut. Cas. Co., 

,
693-94 (Iowa 1993)). The Iowa Supreme Court explained:

      If a proximate cause of an injury is within the included coverage of an
      insurance policy, the included coverage is not voided merely because an
      additional proximate cause of the injury is a cause which is excluded
      under the policy. Thus, in order for an injury to be excluded from
      coverage under an insurance policy, the injury must have been caused
      solely by a proximate cause which is excluded under the policy. The
      insurance carrier has the burden of proof as to whether the injury was
      caused solely by a proximate cause which is excluded under the policy.

(internal quotation omitted).

      Travelers first argues that the windstorm was not an independent or
“proximate” cause of the damage at issue because the windstorm could not, on its
own, have caused the full extent of the damage. According to Travelers, the

      2
        See Amish 

(Hecht, J., dissenting)
(explaining different concurrent causation tests under Iowa law). Although Travelers
makes a passing reference to the efficient proximate cause test, we need not determine
whether the sole proximate cause test or efficient proximate cause test governs.
Travelers arguments remain the same under each: “[T]here are not two independent
causes of loss because the wind did not, and could not have independently caused any
damage whatsoever.” Appellant Br. at 32. Travelers affirms that “[i]n either case,”
referring to whether the faulty workmanship is the sole proximate cause or the
efficient proximate cause, “the loss is not covered.”

                                         -7-
building’s faulty workmanship was necessarily the cause of the magnitude of the
resulting damage. But the Iowa Supreme Court has rejected a similar argument. In
Kalell, for example, it determined that concurrent causes were independent causes
even though each cause did not independently cause the relevant 

. There, when the insured tied a rope to his truck to remove a dead limb from
a tree, the limb struck and injured the plaintiff.

clear that neither the rope
nor the truck, on its own, could have caused the injury. Both were required to
facilitate the process that resulted in the harm. Nevertheless, the Iowa Supreme Court
held that the use of the truck and the use of the rope were independent causes of
plaintiff’s injury.

noted that the use of the rope “could be found to be
an independent act of negligence and one which is covered by the policy.” Id.; see
also 

(Iowa 1993) (holding that negligent supervision of
children “could have been determined to be[] a proximate cause” of the child’s
injuries such that injuries were “not caused solely by vehicle-related negligence”).
Here, likewise, the jury found that the windstorm was an independent cause of the
harm even if it could not have caused the full extent of the harm on its own.

       Travelers next argues that the windstorm was not an independent cause of the
harm because its effects were necessarily dependent on the faulty workmanship. See
Appellant’s Br. at 27 (“[T]he recipe for damage required the ingredient of
Henderson’s faulty work.”). Here, too, we reject the argument that the extent of the
damage caused by the windstorm was dependent on the faulty workmanship. The
cases cited by Travelers in support are inapposite. In City of West Liberty v.
Employers Mutual Casualty Co., “a squirrel found its way onto an electrical
transformer owned by a municipality triggering an electrical arc” which damaged the
municipality’s 

. Although it was undisputed that the
insurance policy at issue covered harm proximately caused by a squirrel, the policy
excluded coverage for any “loss caused by arcing.”

The Iowa Supreme
Court ultimately found that the exclusion applied, because the squirrel was not an
“independent cause” of the harm, see

since its actions caused harm

                                          -8-
only “through the arcing,” which was an excluded cause under the policy and which
did not directly and “by itself” cause the harm.

The arcing alone was the
immediate cause of harm, even if the arcing itself was caused by the squirrel. See

was inextricably tied to the arcing and was the immediate reason why
the arcing happened.”). Here, by contrast, the windstorm and faulty workmanship
operated in tandem to cause the resulting damage, and thus the windstorm and the
faulty workmanship were “two independent causes” that “contributed to the loss,”
unlike the situation in West Liberty, see

        Travelers’s reliance on American Family Mutual Insurance Co. v. Corrigan
fails for a similar reason. 

(Iowa 2005). There, “Mark Francke
operated a daycare business in the home of his father, Harold Francke.”

Mark admitted that he had caused severe injuries to a child that attended the daycare
and pleaded guilty to the crime of child endangerment. See

parents
sued Mark for “negligent, reckless, and/or intentional conduct resulting in serious
harm to [their child].”

Harold for negligent supervision, for failing to
warn of the dangers Mark posed, and for knowingly allowing on his premises dangers
that presented substantial risk of harm to children. See

brought
a declaratory judgment action, asserting that it was not liable for the injuries suffered
by the child, relying on the policy’s criminal acts exclusion, which precluded
coverage for “bodily injury . . . arising out of . . . violation of any criminal law for
which any insured is convicted.”

The child’s parents argued that the
criminal acts exclusion did not apply to their claims against Harold, who was sued
only for negligent supervision. See
 

(“They argue there were two causes of
[their child’s] injuries—Mark’s conduct and Harold’s negligence. . . . [T]he mere fact
that the injury arising from Mark’s intentional acts is excluded does not mean the
same injury also caused by Harold’s negligent acts is excluded.”). The Iowa Supreme
Court disagreed, stating that “the negligent acts of Harold were not independent of
Mark’s criminal acts.”
 Id. at 115. 
See
 

(“The present case is clearly
distinguishable [from Kalell] because the acts alleged against Harold are not

                                          -9-
independent of the excluded acts of Mark.”) “[T]heories of liability asserted against
Harold require as an element proof of Mark’s conduct in inflicting the injuries,” it
reasoned. Moreover, “[b]ecause Mark’s acts must be established to prove that
Harold’s negligence was a proximate cause of [the child’s] injuries, none of the
claims of negligence alleged against Harold are independent of the wrongful conduct
of Mark . . . .”). Here, by contrast, the destructive force of the windstorm existed
notwithstanding the existence of any faulty workmanship on Henderson’s part.
Crucially, the “theor[y] of liability asserted against” Travelers relating to the
windstorm does not “require as an element proof” of the role of faulty workmanship
in “inflicting the [harm].”
 

Thus, unlike in Corrigan, the causal events at
issue here exist independently.

       Travelers further argues that no reasonable juror could have found that faulty
workmanship was not the sole proximate cause of the damages at issue. Under Iowa
law, “save in exceptional cases . . . proximate cause is [a question] to be determined
by the jury and not one to be dealt with as a question of law by the Court.” Walton
v. Eckhart, 
354 F.2d 35
, 38 (8th Cir. 1965) (applying Iowa law); see also Clinkscales
v. Nelson Sec., Inc., 
697 N.W.2d 836
, 841 (Iowa 2005) (“questions of . . . proximate
cause are ordinarily for the jury—‘only in exceptional cases’ should they be decided
as a matter of law” (citing Iowa R. App. P. 6.14(6)(j))). Henderson presented
evidence at trial that the windstorm was a “catalyst” for the damage to the roof.
Accordingly, we conclude that, based on the evidence presented, a reasonable juror
could have found that faulty workmanship was not the sole proximate cause of the
loss.

B. Motion for a New Trial or Remittitur

       Travelers argues that it is entitled to a new trial because the district court erred
in instructing the jury on the definition of “sole proximate cause.” As a threshold
matter, when a party does not preserve a claim related to jury instructions, “this court

                                           -10-
reviews the district court’s instructions for plain error.” Lopez v. Tyson Foods, Inc.,
690 F.3d 869
, 876 (8th Cir. 2012). Travelers did not state the grounds for its
objection to the instruction during trial, and so we review only for plain error. See

id. at 876 
(8th Cir. 2012) (stating that objections to jury instructions “must be
specific, precise enough to allow the district court to address any problems and avoid
a retrial. A general objection to a jury instruction, even when it encompasses a
specific objection is insufficient.” (quoting Bauer v. Curators of Univ. of Mo., 
680
F.3d 1043
, 1045 (8th Cir. 2012))); Fed. R. Civ. P. 51(c)(1) (requiring that objections
to jury instructions state “distinctly the matter objected to and the grounds for the
objection.”). Plain error exists only when:

      (1) the district court deviates from a legal rule; (2) the error is clear
      under current law; and, (3) the error affects substantial rights, which
      ordinarily means that the error affects the outcome of the proceedings.
      Plain error will not be corrected unless (4) it seriously affects the
      integrity, fairness, or public reputation of judicial proceedings.


Id., 690 F.3d 
at 877 (quoting 
Bauer, 680 F.3d at 1045
).

      We find no plain error in the district court’s instruction to the jury on the issue
of proximate cause. The instruction stated:

      When a loss is caused by a combination of covered and excluded risks,
      the loss is covered unless the excluded cause is the sole “proximate
      cause” of the loss. An event is considered a proximate cause of a loss
      if the event sets in motion other causes which, through an unbroken
      sequence and combination, result in the loss. There can be more than
      one proximate cause.

This instruction is consistent with the Iowa Supreme Court’s prior construction of
“proximate cause” in insurance liability cases. See, e.g., Qualls v. Farm Bureau Mut.
Ins. Co., 
184 N.W.2d 710
, 713 (Iowa 1971) (explaining that a proximate cause “sets

                                          -11-
other causes in motion which, in an unbroken sequence and connection . . . produces
the result for which recovery is sought”); 
Kalell, 471 N.W.2d at 868 
(“Under Iowa
law, [m]ore than one proximate cause may exist.”). Regardless of whether the district
court erred in giving the instruction, Travelers has not shown that the error affected
the outcome of the proceedings.

       Travelers also contends that remittitur is appropriate, arguing that the district
court awarded grossly excessive awards for the cost of the roof replacement and
engineering assessment fees. Remittitur is only “appropriate where the verdict is so
grossly excessive as to shock the judicial conscience.” Bennett v. Riceland Foods,
Inc., 
721 F.3d 546
, 553 (8th Cir. 2013). “A new trial or remittitur is not appropriate
‘merely because [we] may have arrived at a different amount from the jury’s award.’”
Lincoln Composites, Inc. v. Firetrace USA, LLC, 
825 F.3d 453
, 459 (8th Cir. 2016)
(quoting 
Bennett, 721 F.3d at 553
). We conclude that the total award, however
generous it may have been, is not so “excessive as to shock the judicial conscience.”

      The judgment is affirmed.
