Insurer Granted Summary Judgment on Claim for Roof Damage Caused by Windstorm

May 26, 2026 — Tred R. Eyerly - Insurance Law Hawaii
The insurer successfully moved for summary judgment, eliminating the insured’s claim for roof damage due to windstorm. Mulas v. Westchester Surplus Lines Ins. Co., 2026 U.S. Dist. LEXIS 20537 (Jan. 30, 2026). The insureds’ commercial property sustained windstorm damage during Hurricane Ian. Westchester denied the claim. The insureds believed Westchester wrongfully denied coverage for roof damage and various interior damage to property. The insureds also argued that Westchester’s actual cash value (ACV) payment did not reflect the fully insured loss. The insureds sued and Westchester moved for summary judgment. Westchester argued the roof damage was not covered because Hurricane Ian did not cause the damage. Westchester hired an engineer who determined the roof damage was not caused by wind from Hurricane Ian. Westchester pointed out that the insureds’ expert also found no wind damage on the roof. The insureds offered no other evidence suggesting the hurricane caused roof damage. Therefore, the insureds could not show that Westchester breached the policy by denying coverage.

Preventing Common and Costly Water Intrusion Events in Construction

July 13, 2026 — Andrew Swift - Construction Executive
Water leaking into a building is a leading cause of damage and loss in the construction industry. On one jobsite, heavy rains flooded a sub-basement, damaging a new electrical transformer—all because a roof drain was not property connected. On another jobsite, a drinking-fountain supply line broke in a multistory building that was undergoing renovation, causing water to run—undetected—for an entire weekend, resulting in water damage to all lower floors, where construction had been finished. Those loss scenarios could have been prevented with a comprehensive and effective water damage prevention plan (WDPP). This includes routine site inspections to identify uncontrolled water damage exposures and basic maintenance to make sure drains are clean of debris and divert them to a catch basin or low point away from the building. An effective WDPP plan also incorporates technology such as backflow preventers on sewer connections and water sensing technology to monitor the most vulnerable exposures.

Prefatory Contract Language Cannot Be Used to Create an Ambiguity with Operative Provisions

May 12, 2026 — David Adelstein - Florida Construction Legal Updates
Contract drafting and interpretation matters. A case dealt with the potential conflict with prefatory language in an agreement compared with operative provisions in the agreement. The trial court held that the operative provisions control. I discussed this case here where the appellate court reversed based on the prefatory language. But, through a motion for rehearing, the appellate court reconsidered its position and affirmed the trial court based on the operative provisions, mainly that the prefatory language cannot be used to create an ambiguity with operative provisions. Consider this explanation in affirming the trial court:

Because the trial court correctly found that the initial language in the contract was prefatory and could not be used to create an ambiguity in the remainder of the contract, we affirm the final judgment.

Federal Court Highlights the Strategic Value of Additional Insured Coverage

June 22, 2026 — Michael S. Levine - Hunton Insurance Recovery Blog
A recent decision from the District of Maryland underscores a recurring—but often underutilized—opportunity for policyholders: securing and enforcing additional insured coverage under another party’s liability policy. In Charter Oak Fire Insurance Co. v. Builders Premier Insurance Co., the court held that an equipment lessor qualified as an additional insured under the lessee’s policy and was entitled to a primary defense. The decision is a useful reminder that additional insured coverage can fundamentally shift defense obligations and materially reduce a policyholder’s exposure. We build on the decision to highlight the practical steps policyholders should take to ensure that all potentially available insurance is identified and pursued. Read the full story...

Your AEC Firm Has a Memory Problem. Here Is How to Fix It

June 01, 2026 — Aarni Heiskanen - AEC Business
AEC companies trying to operationalize AI often find they lack the data foundation on which to build. There may be an abundance of data hidden in documents, but you can’t reliably use it for AI. The lack of data quality was a key topic discussed at the AI in AEC 2026 conference. During the event, I met many experts working to solve this problem, including Pavlina Nikolova, Egnyte‘s EMEA AEC Practice Lead. The chat and her presentation highlighted the challenges and ways to overcome them. Read the full story...

The GKN Aerospace Chemical Release and the Laws Designed to Address It

July 06, 2026 — Sean M. Sherlock - Snell & Wilmer
On May 21, 2026, a 34,000-gallon storage tank at the GKN Aerospace facility in Garden Grove, California began leaking methyl methacrylate (MMA), a volatile and highly flammable industrial chemical used to manufacture high-strength acrylic plastics. GKN Aerospace makes advanced military and commercial transparencies, such as aircraft canopies, windshields, cabin windows, bullet-resistant glass, and spacecraft windows. In polymer chemistry lingo, MMA is known as a monomer. Monomers are like individual links to a chain. Under the right conditions they link up (react) with each other to form long-chained polymers, or plastics. MMA is an unstable monomer that requires controlled storage conditions to avoid setting off a polymerization (chain) reaction. According to early reports, the MMA tank at GKN Aerospace overheated. The cause of the overheating is not yet clear, but the overheating may have created conditions enabling the MMA to initiate polymerization, which in turn generated heat, which in turn generated pressure, activating the tank’s pressure-relief system and releasing MMA vapor into the atmosphere. Concerns about a runaway reaction, massive release, and explosion led the Orange County Fire Authority to order evacuation of approximately 40,000 residents and closure of thirteen schools.

Kahana Feld Obtains Favorable Result in High-Exposure NY Premises Liability Case

June 15, 2026 — Leigh Katz - Kahana Feld
Kahana Feld partner Leigh Katz obtained a significant victory in a recent matter involving a videotaped alleged trip and fall on the sidewalk in front of the client’s commercial residence. The plaintiff claimed he suffered a knee injury that necessitated surgery, along with other assorted injuries that prevented him from continuing high-level athletic activities. Leigh was able to demonstrate that the fall was staged and received a voluntary discontinuance with prejudice. At mediation, Leigh emphasized that KF’s expert witness challenged the plaintiff’s claim that the fall was caused by a sidewalk height differential after reviewing the videotape footage and determining the plaintiff’s fall began before his feet made contact with the alleged defect. Based on this analysis, the expert concluded the reported height differential did not initiate the fall, which supported KF’s position that the incident depicted in the video was unrealistic and appeared staged.
