Triple Investment Group, LLC v. Hartford Steam Boiler Inspection & Insurance, 71 F. Supp. 3d 733

Background

Triple Investment Group (plaintiff) purchased the Pontiac Silverdome (a fabric, air‑supported roof) and an equipment‑breakdown insurance policy from Hartford Steam Boiler (defendant) effective Dec. 1, 2012–Dec. 1, 2013.
The Silverdome roof system relied on multiple furnaces and rooftop makeup units; plaintiff alleges the north indirect furnace (North Furnace) failed to start on Dec. 24, 2012, causing localized ice accumulation and a tear in the roof on Dec. 29, 2012.
Plaintiff arranged temporary repairs (a stop‑patch) Dec. 31, 2012, but alleges further tearing and deflated the roof on Jan. 2, 2013; gale‑force winds then destroyed the roof by Jan. 20, 2013.
Plaintiff notified defendant of the furnace failure on Jan. 25, 2013 (30 days after the alleged failure); defendant inspected the site multiple times and denied coverage July 19, 2013.
Plaintiff sued for breach of the equipment‑breakdown policy seeking >$20 million; defendant moved for summary judgment arguing (1) untimely notice and prejudice, and (2) the roof destruction was not the direct/sole result of a covered ‘‘accident.’’
The court granted defendant’s motion: it found notice was not prompt and that, even assuming a furnace ‘‘accident,’’ the roof loss was not solely attributable to that accident (weather and plaintiff’s deflation intervened).

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Was notice of loss "prompt" under the policy?	Plaintiff: 30‑day delay was reasonable under the circumstances of a crisis and repairs; promptness should be measured "as soon as practicable."	Defendant: 30‑day delay was untimely; insurer deprived of the opportunity to investigate and mitigate; prejudice resulted.	Held: Notice was not prompt as a matter of law and the delay materially prejudiced defendant.
Must insurer show prejudice from late notice?	Plaintiff: Insurer must show specific prejudice; here there was none because roof was already destroyed.	Defendant: Prejudice shown because defendant lost access to examine furnace and initial roof condition, destroying key defenses.	Held: Insurer demonstrated material prejudice (loss of opportunity to investigate); prejudice established as a matter of law.
Is roof destruction a covered "accident" under Equipment Breakdown coverage?	Plaintiff: Mechanical breakdown of North Furnace was a fortuitous event that led to ice accumulation and ultimately roof destruction; chain of events is one covered accident.	Defendant: Even if furnace malfunction was a covered accident, policy covers only loss "solely attributable" to the accident; wind damage and other factors (and plaintiff’s deflation) break the causal chain.	Held: Even assuming a covered furnace accident, roof destruction was not solely attributable to it and thus not covered.
Did plaintiff mitigate loss and preserve insurer's rights?	Plaintiff: Emergency actions were necessary; roof could not have been saved.	Defendant: Plaintiff intentionally deflated the roof and prevented insurer investigation and possible repair—worsening loss.	Held: Plaintiff’s actions (and timing) precluded insurer from investigating and mitigating; this supports summary judgment for defendant.
