builder open the roof last week to complete the extension. it was raining heavily last night and water came into the ceiling of the bedroom facing the new extension. most of the water came out of the ceiling rose which made the light build exploded. when I go out to the extension and touch the newly build wall and the scaffolding pole I get electric shock. the same happened when I touch the kitchen sink with barefoot in the kitchen. I have three small children and I am very worried about their safety. what is the reason of the electric shock and how it an be eliminated?

You need to get an electrican in to sort it out urgently!
Your consumer unit should have tripped as water ingress should have caused sufficient current to flow through the earth to trip.
Can you turn off the circuit affected at the consumer unit, or get a neighbour to have look.
I wouldnt leave it like that overnight with small children, you have live fault which is potentially dangerous
neither the light circuit breakers nor the sockets tripped. also forgot to mention the electric shock is what I call mild and more effective on the wall then the kitchen sink but still get me very worries. I did switch off the light circuit and noticed nothing when touch the kitchen sink. but I did not do this with the wall as it is too dark to go outside now.

How can you deduce this? Have you been there to take measurements?
It could be any number of fault conditions, hence my advice: get an electrician in.

To get shocks like you describe, safety items must be either faulty or missing, the thing we call a RCD should have disconnected to supply, it would have been required in a new build which would include an extension so that item is not working.
The test gear to check the RCD will cost a lot of money, so there is no alternative other than call an electrician. Water may have caused the problems but it should have resulted in you loosing power, not getting a shock.

You must be pretty athletic to do that

At least the shock won't go through the heart.
yeah I wondered about that, I think it may be a grammar thingYou must be pretty athletic to do that
an electrician came today and did some tests. he found the earth is one single silver naked wire running a long the wires that carry the live and the natural. He concluded that it might be in one of the wet junction boxes live electricity escaping to the earth. there is no RCD in the house at all and that is why nothing has tripped. also the normal circuit barkers did not trip because they only work with natural and live not live and earth

What action has he taken to solve the problem ?
Well.
After you get your current problem fixed, you should ensure that RCDs/RCBOs are installed to protect you and your loved ones (as far as is possible) from such untoward events.
(By the way, electricity does not "escape to the Earth".
The current in any circuit returns to its source - conventionally stated, this is via the Neutral, which is "Neutral" because it is connected to the Earth.")
