Rainwater Damage as an “Ensuing Loss” Under Construction-Defect Exclusions; Fungi Additional Coverage as an Exception to the Fungi Exclusion (Wisconsin)

Introduction

Case: Cincinnati Insurance Company v. James Ropicky, 2026 WI 25 (Wis. July 7, 2026)
This homeowner-coverage dispute arose after a 2018 storm allegedly caused rainwater to pour into James Ropicky’s home, producing extensive damage. Cincinnati Insurance Company investigated and concluded the water entered through a construction defect (a “one-inch gap” near roof flashing/gutter) that existed since original construction, with years of recurring intrusion and resulting fungal deterioration. The policy included (1) a construction-defect exclusion with an “Ensuing Loss Exception,” and (2) a fungi exclusion with $10,000 “Fungi Additional Coverage.”

The central issues were (i) what counts as an “ensuing” loss when water enters due to an alleged construction defect, (ii) whether “Fungi Additional Coverage” is an exception to, or instead makes inoperative, the policy’s fungi exclusion (including its anti-concurrent-cause clause), and (iii) whether summary judgment was appropriate given disputed facts about defect existence/causation and fungi presence/causation.

Summary of the Opinion

The Wisconsin Supreme Court (Hagedorn, J.) affirmed the court of appeals’ reversal of summary judgment and remanded for further proceedings. The Court held:

  • Construction Defect / Ensuing Loss: In this case, physical losses caused by rainwater constitute an “ensuing” loss within the meaning of the Ensuing Loss Exception to the Construction Defect Exclusion.
  • Fungi Coverage Structure: The Fungi Additional Coverage is an exception to the Fungi Exclusion, not an independent grant that renders the exclusion wholly inoperative.
  • Summary Judgment: Genuine disputes of material fact exist regarding (a) whether key construction defects existed (including the alleged gap) and what portion of loss they caused, and (b) whether fungi was present and the extent to which it caused loss. Summary judgment for Cincinnati was therefore improper, and the dismissed bad-faith claim must be reinstated on remand.

A dissent (Ziegler, J.) argued the majority improperly broadened Arnold v. Cincinnati Ins. Co. and that ensuing-loss coverage should require an independent, distinct cause beyond water entering through faulty construction.

Analysis

1. Precedents Cited

A. Wisconsin interpretive framework and burdens

  • 5 Walworth, LLC v. Engerman Contracting, Inc., 2023 WI 51: Cited for de novo review of policy interpretation and summary-judgment principles.
  • Wadzinski v. Auto-Owners Ins. Co., 2012 WI 75: Reinforces that policy language is construed as a reasonable insured would understand it, with attention to the policy’s purpose and expected coverage.
  • Am. Family Mut. Ins. Co. v. Schmitz, 2010 WI App 157: Establishes the insured’s burden to show an initial grant of coverage and the insurer’s burden to prove an exclusion.
  • Just v. Land Reclamation, Ltd., 151 Wis. 2d 593 (Ct. App. 1989), rev’d on other grounds, 155 Wis. 2d 737 (1990): Cited for the rule that the insured bears the burden to prove an exception to an exclusion. The Supreme Court noted the issue was not renewed in this review but accepted the framework.

B. Ensuing-loss doctrine in Wisconsin

  • Arnold v. Cincinnati Ins. Co., 2004 WI App 195: The controlling Wisconsin precedent on “ensuing loss” exceptions to workmanship/defect exclusions. The Supreme Court adopted Arnold’s reasoning and applied it directly here. In Arnold, damages directly caused by faulty workmanship were excluded, but interior damage caused by rain leaking through compromised seals was treated as an ensuing loss because rain was a cause “in addition to” the faulty work.
  • State v. Lira, 2021 WI 81, and Evers v. Marklein, 2024 WI 31: Cited to explain the Court’s prudential caution in upending long-standing, statewide court of appeals interpretations on which parties and insurers may rely.

C. Competing national approaches (persuasive authorities)

The Court discussed the national split on ensuing-loss provisions and used out-of-state cases to situate Arnold’s approach.

  • “Proximate cause”/chain-break approaches: Friedberg v. Chubb & Son, Inc.; Prudential Prop. & Casualty Ins. Co. v. Lillard-Roberts; TMW Enterprises, v. Federal Ins. Co.. These authorities illustrate a narrower view requiring a causal break or a new efficient proximate cause to trigger ensuing-loss coverage.
  • Broader consequential approaches: Leep v. Trinity Universal Ins. Co.; BSI Constructors, Inc. v. Hartford Fire Ins. Co.; Selective Way Ins. Co. v. Nat’l Fire Ins. Co. of Hartford; 19900 W Nine Mile, LLC v. Hanover Ins. Co.; Dawson Farms, L.L.C. v. Millers Mut. Fire. Ins. Co.; Bartram, LLC v. Landmark Am. Ins. Co.; Eckstein v. Cincinnati Ins. Co.. These cases help frame readings that allow coverage for later damage consequentially following defective work.
  • “Independent covered loss” requirements: Taja Inves. LLC v. Peerless Ins. Co., cited as representing approaches insisting on a subsequent independent covered loss.

D. “Does not apply” as an exception (Wisconsin coverage structure)

  • American Family Mutual Insurance Company v. American Girl, Inc., 2004 WI 2: Central to the fungi issue. The Court used American Girl to show that policy language stating an exclusion “does not apply if...” is routinely read as creating an exception restoring coverage, not abolishing the exclusion’s existence.
  • The opinion (through the Neubauer concurrence’s citations) referenced Wisconsin cases treating “does not apply” language as exception structure: 5 Walworth, LLC v. Engerman Contracting, Inc., 2021 WI App 51; Vandenberg v. Continental Ins. Co., 2001 WI 85; Ruff v. Graziano, 220 Wis. 2d 513; Heikkinen v. United Servs. Auto. Ass’n, 2006 WI App 207; U.S. Fire Ins. Co. v. Good Humor Corp., 173 Wis. 2d 804; Heinecke v. Aurora Healthcare, Inc., 2013 WI App 133.

E. Procedure: summary judgment standards

  • Quick Charge Kiosk LLC v. Kaul, 2020 WI 54: De novo summary judgment methodology.
  • Physicians Plus Ins. Corp. v. Midwest Mut. Ins. Co., 2002 WI 80, and Metro. Ventures, LLC v. GEA Assocs., 2006 WI 71: Emphasize viewing evidence and inferences in the non-movant’s favor and focusing on what a reasonable jury could conclude.

F. Burden-of-proof support from other jurisdictions

Although not outcome-determinative here, the Court cited: Kesling v. Am. Fam. Mut. Ins. Co., Hudnell v. Allstate Ins. Co., and Telepak v. United Servs. Auto. Ass’n to note that allocating to the insured the burden to prove an exception aligns with other jurisdictions.

2. Legal Reasoning

A. Ensuing-loss meaning: reaffirming and adopting Arnold

The Court framed the interpretive problem as a tension: the policy excludes “physical loss” caused by defective construction, yet restores coverage for “any ensuing ‘physical loss’” from that defect (so long as not otherwise precluded). The Court’s objective was to harmonize exclusion and exception so neither becomes illusory.

The Court rejected Cincinnati’s proposed “proximate cause”/causal-chain-break requirement as inconsistent with the policy text and with ordinary meaning of “ensuing.” Instead, it adopted Arnold v. Cincinnati Ins. Co.’s approach: an ensuing loss is one that follows as a consequence and involves a cause “in addition to” the excluded cause—without demanding a dramatic, independent intervening peril that breaks causation.

Applying that rule, the Court held rainwater intrusion can qualify as the additional cause: where a defect allegedly permits rainwater entry, the cost to fix the defect remains excluded, but damage caused by rainwater that follows as a consequence may fall within the Ensuing Loss Exception (subject to other policy limitations).

B. Fungi structure: additional coverage as an exception to the exclusion

The fungi dispute was largely structural: does “This exclusion does not apply... [t]o the extent coverage is provided...” mean the exclusion is never triggered (court of appeals majority), or does it mean the exclusion applies but is carved back by an exception (Judge Neubauer and Cincinnati)?

The Supreme Court sided with the exception structure. Relying on American Family Mutual Insurance Company v. American Girl, Inc., it treated “does not apply if...” as conventional exception language that restores otherwise excluded coverage up to the purchased endorsement’s limit ($10,000). This reading avoids the conceptual misstep that exclusions and exceptions “contradict” each other; rather, exceptions are designed to reintroduce limited coverage that an exclusion would otherwise remove.

The Court further indicated that, because the additional coverage is an exception, the anti-concurrent-cause language embedded in the exclusion does not operate to defeat coverage where the exception is triggered (though here Cincinnati had already paid the $10,000 fungi limit).

C. Summary judgment: causation and existence disputes are for the factfinder

With the coverage interpretations clarified, the Court found genuine disputes of material fact, including:

  • Existence of the key rear-wall “gap” defect: Conflicting testimony existed about whether a one-inch gap existed before siding removal and whether it violated code/plans (bearing on whether it was a “construction defect” as alleged).
  • Scope and apportionment of loss: Even where Ropicky conceded certain defects (front/north tower area and other construction-quality issues), the record did not conclusively establish what portion of damage was attributable to admitted defects versus other causes and what portion constitutes covered ensuing loss.
  • Fungi presence and causation: Experts disagreed about whether observed damage was fungal rot versus delamination from sudden saturation, and the chain of custody/storage of samples (Bagster exposure; garage storage; potential mold growth) created fact questions about reliability and timing of fungal growth.

These disputes precluded summary judgment, required remand, and necessitated reinstatement of the bad-faith claim that had been dismissed as a consequence of the erroneous summary judgment.

3. Impact

A. Clarified rule for water intrusion under construction-defect exclusions

The most consequential doctrinal move is the Court’s explicit holding that, under this policy language and Wisconsin law, rainwater-caused physical loss can be an ensuing loss even when the rainwater enters through an alleged construction defect. This effectively strengthens insureds’ ability to obtain coverage for resultant interior/property damage, while preserving the insurer’s ability to exclude the cost of repairing the defect itself.

B. Policy-drafting and litigation dynamics

The Court emphasized reliance on the longstanding meaning of the clause as interpreted in Arnold v. Cincinnati Ins. Co.. Practically, insurers doing business in Wisconsin may respond by:

  • Rewriting ensuing-loss clauses with more precise causal requirements (if they seek a narrower rule);
  • Adjusting definitions of “construction defect,” “physical loss,” or water-damage limitations;
  • Reassessing claims-handling protocols (including investigations and expert retention) knowing that rainwater may be treated as an ensuing cause and that causation allocation is likely to reach juries where records are contested.

C. Fungi endorsements: structural clarity and anti-concurrent-cause limits

By characterizing the Fungi Additional Coverage as an exception, the Court reinforces a standard interpretive architecture: exclusions can be partially “granted back” by endorsements. This reduces the likelihood that “does not apply” wording will be argued to erase the exclusion wholesale, and it cabins the anti-concurrent-cause clause when the exception is triggered.

D. Procedural impact: summary judgment in complex causation insurance cases

The opinion signals skepticism toward resolving technical causation disputes on summary judgment where expert methodology, investigation quality, and sample integrity are contested. Parties should expect greater emphasis on: (i) reliable, documented investigation methods; (ii) preserved physical evidence and chain-of-custody; and (iii) careful causation apportionment between excluded defect repair, covered ensuing water damage, and limited fungi coverage.

4. Complex Concepts Simplified

  • Construction Defect Exclusion: A policy term that denies coverage when the loss is caused by faulty design/workmanship/materials. It is aimed at preventing homeowners’ policies from functioning as warranties for builders’ work.
  • Ensuing Loss Exception: A “give-back” clause that restores coverage for certain later damage that follows from an excluded cause. Here, the Court treated rainwater damage as the kind of later harm that may be covered even if a defect allowed the rain in.
  • Anti-Concurrent Cause Clause: Language stating that if an excluded peril contributes “directly or indirectly” to loss—concurrently or in sequence—coverage is barred. The Court’s fungi analysis indicates that when an exception/endorsement applies, that exclusionary machinery does not defeat the limited restored coverage.
  • Exception vs. independent grant of coverage: An exception restores coverage that an exclusion would otherwise remove; an independent grant would provide coverage without regard to the exclusion. The Court held the fungi endorsement operates as an exception.
  • Delamination vs. fungal rot: “Delamination” is mechanical separation/deterioration of wood layers from sudden saturation; fungal rot is biological decay. The distinction matters because fungi-triggered damage may be capped/limited, while non-fungi water damage may be covered as ensuing loss.
  • Summary judgment: A pretrial ruling appropriate only when no material facts are genuinely disputed. Competing expert opinions, contested defect existence, and disputed evidence integrity commonly defeat summary judgment.

Conclusion

Cincinnati Insurance Company v. James Ropicky establishes (and expressly embraces) a Wisconsin rule that, under common ensuing-loss language, rainwater-caused physical loss can qualify as an ensuing loss notwithstanding an alleged construction defect that facilitated the intrusion—while still excluding the cost of fixing the defect itself. The Court also clarifies that Fungi Additional Coverage functions as an exception to the fungi exclusion (rather than nullifying it), preserving standard exclusion/exception architecture and limiting arguments that “does not apply” eliminates exclusions wholesale.

Just as importantly, the decision is a procedural reminder: where defect existence, causation, and evidence reliability are genuinely disputed, Wisconsin courts should not short-circuit coverage litigation at summary judgment. The opinion positions juries—and rigorous factual development—as central in multi-cause property-loss disputes involving construction defects, water intrusion, and alleged fungi damage.
