Had a roof leak -- water went into wall -- wires got wet. Got a shock and had wall tested for voltage. One point on metal from slider door and other on drywall -- It read 120V. Repairs have been made to roof, ceiling --- wires have dried. Now only showing 4V. Is this normal or is their still a problem?

Forgot to add one thing -- about a foot down from the low voltage reading is a light switch -- could that be the source of the voltage reading?

It's not normal to have voltage in your drywall. The reason it read 120v when it was wet was because as we all know, water conducts electricity. Now that its dry, it measures 4v. That is because the drywall has more resistance than water. 120v are still applied to it but with more resistance therefore, giving you 4v. Look around for loose connection or for nails/screws that might have puncture the insulation of a wire. Have an electrician come out. The problem should be close to were your problem exist.

You have a problem, v should go up as you near the source, but I would start outside the Sliding Door , look at the Light out there for a short.

Maybe someone drywalled over a wired outlet box.

YOU HAVE A SHORT! I SAW THE SAME THING IN A MASONRY WAY, THE BRICK LAYER USED TOO LARGE A NAIL WHICH HIT A WIRE! IT MANIFESTED AS A MILD SHOCK FROM A MILL FINISH ALUMINUM WINDOW....... ONLY........ AFTER A HEAVY RAIN & THE BRICK WALL WAS SOAKED, & CONDUCTED ENOUGH JUICE TO MILDLY ELECTRIFY THE WINDOW. TOOK A WEEK TO FIGURE OUT!

sometimes drywall can conduct a static charge but I've never heard of that you should call someone because it could be a number of different things

You'll find voltage reading everywhere electric lines run near by.
The 4 v. reading is o.k. it won't present any hazards. Still, have a licensed electrician tell you this and charge you at least $50 bucks.
