Call the contractor and have it fixed. Were they install correctly. Are all the vents leaking or just one? Were they sealed? A properly installed vent shouldn't leak even if it has not been sealed.

You should shingle to a point and then put the vent on and shingle on top of the nailing flange from one third to one half of the sides of the vent depending on where it comes on the rows.

It may be leaking at the drain plug located at the bottom of the pump housing. It may be leaking throught the gasket/o-ring that seal the pump cover to the pump housing. The seal may be installed incorrectly. There may be a crack in the pump housing/cover assembly. You may be able to observe water squirting fron the leak by watching the pump while it is running.
Usually a leaking hose into or out of the water pump (depending on its location), or the water pump gasket.

Bottom drip.
