Do you have an burglar alarm?  There are addons that do this for them,
including wireless ones.

We've got a bunch of these:

They're really loud, so they might be enough.  The sensor is just a
pair of contacts.  Water completes the circuit, and sets off the
beeper.  You can cut the wires and splice in a longer wire.  (lowes
webstie says 100'.  I expect the limit is because it's driving the
beeper with the current sent through the sensor.  If you know any
electronics, that's easy to fix...)
