What is an ensuing loss in property insurance?
An ensuing loss is damage that follows an excluded cause and is itself covered. The exclusion removes the defective thing; the ensuing loss provision restores the separate damage it goes on to cause. Florida draws the line hard: the cost of correcting the excluded defect is never an ensuing loss.
| Where it lives | Inside the exclusion, as a carve-back beginning: but this exclusion shall not apply to |
|---|---|
| What it covers | Separate, resulting damage to other property |
| What it never covers | The cost of correcting the excluded defect itself, Swire Pacific Holdings v. Zurich, Fla. Sup. Ct. 2003 |
| Typical hurricane claim | Faulty repair or workmanship excluded, the water damage that follows covered |
| Why it is fought | Carriers read the exception narrowly enough to disappear, courts read it narrowly enough to keep the exclusion alive |
What an ensuing loss actually means
Property policies exclude certain causes and then, in the same breath, give part of the coverage back. Faulty workmanship is excluded, but the water damage that pours through the roof a contractor left open may not be. Wear and tear is excluded, but the ceiling collapse that follows may be covered. That carve-back is the ensuing loss provision, and it usually reads as a sentence tacked onto the exclusion: this exclusion shall not apply to physical loss or damage resulting from that cause.
The line the courts draw is between the defect and its consequences. In Swire Pacific Holdings, Inc. v. Zurich Insurance Company, decided April 10, 2003, the Florida Supreme Court held that the cost of correcting an excluded design defect is not an ensuing loss, reasoning that reading it that way would eviscerate and consume the design defect exclusion and turn a builder's risk policy into a warranty against defective work.
So every ensuing loss dispute reduces to one question: is the damage being claimed the excluded thing, or is it separate property damaged because of the excluded thing? The second is covered. The first never is.
What an ensuing loss does to a hurricane claim
Separate the two categories on paper. One column for the excluded cause and what it costs to correct: the failed repair, the worn shingle, the defective flashing. A second column for everything that cause then damaged: drywall, insulation, flooring, cabinets, contents. Only the second column is being claimed.
Do not claim the first column by accident. A single estimate that blends the repair of the defect with the resulting damage lets a carrier deny the whole line under Swire.
Get the causation sequence stated in writing. An independent engineer or contractor who describes the excluded cause first and the resulting damage second gives the file the structure the carve-back requires. Start with how to rebut an engineer report.
Read the exclusion word for word. Ensuing loss language is not standard across forms, and some exclusions carry anti-concurrent causation language that overrides the carve-back entirely.
Exclusion
Policy language removing a cause of loss or type of damage from coverage. Exclusions are read narrowly against the drafter in most jurisdictions, and the carrier carries the burden of proving one applies.
Anti-concurrent causation clause
Policy language stating that if an excluded cause contributes in any sequence to the loss, the entire loss is excluded even where a covered cause also contributed. It is the clause behind most wind-versus-flood denials.
Latent defect
A hidden flaw in materials or construction that was not discoverable by reasonable inspection. Excluded as a cause, though the damage that ensues from it may still be covered.
Wear and tear
Gradual deterioration from age and exposure, excluded by every property policy. Reclassifying storm damage as wear and tear is the single most common denial move on roof claims.
