Not fire, not wind. Water is the leading cause of building loss

The number that surprises people

Ask an owner what they insure against first and most will say fire. The data says something else. More than forty percent of building losses come from water damage. Not fire. Not wind. Not earthquakes. Water.

It is the most frequent and one of the most expensive loss categories in the built environment, and it is also the most preventable. That combination, common, costly and avoidable, is exactly why it has moved to the center of the conversation between buildings and the carriers who insure them.

Why carriers are paying attention

The insurance industry has noticed, and it is changing how it treats water risk. Zurich now points to water sensors as a standard practice rather than a nice-to-have. Aon has described how flow monitoring and automatic shutoff are reshaping underwriting conversations. Industry coverage in outlets like Business Insurance keeps returning to the same theme: the shift from paying claims to preventing them is underway.

The logic is straightforward. A loss that never happens is better for everyone than a loss that gets paid out. When a building can show real-time detection, instant alerts and automatic shutoff, the carrier is looking at a measurably lower-risk asset, and that shows up in the terms.

From reactive to proactive

For decades, water risk was managed reactively. A leak happened, a claim was filed, a deductible was paid, and the cycle repeated. Prevention technology breaks that loop. Continuous monitoring catches the event while it is small, automatic shutoff stops it from spreading, and a live response team makes sure someone acts even after hours, when most water damage actually occurs.

The result is not just fewer claims. It is data. A monitored building generates a record of what was caught and what was prevented, and that record is becoming part of how risk gets priced. Underwriting is moving from a guess about a building's exposure toward evidence of how that building actually behaves.

What this means for owners and brokers

For owners, the message is that water is the risk most worth getting ahead of, because it is the one most likely to cause a loss and the one most rewarded for prevention. Reducing water exposure is one of the clearest ways to improve both your risk profile and your insurance outcomes.

For brokers, prevention technology is becoming part of the value you bring to a placement. A client with documented, monitored protection is an easier risk to place and a stronger story to tell an underwriter. The conversation is shifting from "what is your deductible" to "what is your building doing to prevent the loss in the first place."

Eddy supports this shift with real-time detection, instant alerts and automatic shutoff, backed by a 24/7 monitoring center and a dataset spanning more than 130,000 installed devices. Smart buildings are not defined by flashy technology. They are defined by eliminating preventable losses, and water is the single biggest opportunity to do exactly that.

The takeaway

Fire gets the attention. Water causes the losses. The buildings and the brokers that treat water as the primary risk, and prevention as the answer, are the ones writing the better outcomes, on the repair bill and at renewal.
