Straight answers

Cold water tank maintenance, your questions

Water dripped through the ceiling from the loft, the tank?
Very likely its float valve or overflow. Turn off the stopcock, and if you can safely reach the loft, tie the float arm up to stop the fill. Then call, the fix is small if it's caught early.
My tank is galvanised steel, replace it?
If it's galvanised it's decades old and rusting from inside. Replace on your schedule (£380–£600 fitted) rather than the tank's, its schedule involves a ceiling.
Do tanks need cleaning?
They benefit from it, and any tank without a close-fitting lid needs one fitted more than it needs cleaning. Open tanks collect what lofts contain; none of it improves your bathwater.
