If the problem is water from a leaky roof then it has to be addressed, but the reason for the power failure at those locations may be that a GFCI receptacle has operated. Check your kitchen outlets and see if one of them needs to be reset.

It would be unlikely (though not impossible) that there is a GFCI in play here. Pretty much from the time countertop receptacles required GFCI, they were also required to be separate from the lighting. Of course almost anything is possible in a retrofit in older houses.

You should certainly find the breaker/fuse involved. It's possible it's already tripped and you over looked it (move the affected handle full off and then back on).

It's also possible that either the bulb blew (they don't like getting wet in most cases) or the fixture was damaged by the water. But you definitely need to get to the bottom of the water problem. The electrical issues are the tip of the iceburg. Structural rot, mold, etc... are likely to ensue. It's also possible that it's a pipe leaking (and perhaps a waste pipe...been there, done that).

Thanks for responding, both of you. I'd never heard of a GFCI, but it had in fact tripped. I wasn't aware that it existed. I called an electrician the next morning, and he pointed it out to me. So in a way it was a waste of his time and my money, but now I know about the receptacle, and I have a good electrician in my rolodex.

The roof leak was the source of the problem, and I'm still looking for someone to fix it.

Thanks again!

A good electrician is a good resource to have handy and he got paid so it wasn't a waste of his time and you learned something (both about your home wiring and who you can trust when you have a bigger problem) so it wasn't a waste of money either.

Get the roof fixed. Water leaking into electrical is fire hazard. I can also cause mild and structure issues which can get costly to fix .
