Usually when a heater core leaks, it is inside the car. Outside the car, I would suspect a heater hose leaking if it getting onto your windshield.

Sounds more like water pump to me. Coolant leaks from the pump to the belt and pulleys which slig it to the top of the engine bay. Air currents take it from there to windshield and roof.
