Well! Leakage comes from the root word “Leak” , means nearly the same thing. Guess it should be a noun of Leak. Leakage is the act of leaking.
Leak itself can be used as a noun and verb.
Example to use both of them:
There is a leak (noun) in the roof. And during rainy season, the water starts to leak (verb) through it. Something should be definitely done to fix this water leakage (noun).
