Controlled Water Test Questions

How much does a controlled water test cost?

A controlled water test starts at $2,900. We'll confirm the scope once we understand the property and the leak.

When does a water test make sense?

It makes sense when a leak keeps coming back after repairs or only shows up in certain storms. It also helps when there's more than one possible source, or when a Dad Check didn't find a clear cause.

Will the test find the exact cause of my leak?

A controlled test can help narrow the cause of a leak. Concealed conditions and multiple failure points may need further investigation, and we'll walk you through what we found and what comes next.

Is a water test the same as a Dad Check?

No. A Dad Check is an inspection of your roof and everything that touches it. A water test runs water on specific areas in stages while we watch from inside, so we can see where water actually gets in.
