There are many possible parts of the roof potentially leaking but one of the most common ones is the area around the roof vent.
Turbine roof vent leaks.
These can be ridge vents wind turbines or the flat vents your roofer wants to install.
You may have a ridge vent turbine vent powered air vent or free air vent.
Both can go out but i see more power vents out than turbines especially since the turbines i use are guaranteed for life.
Turbine vents are a type of exhaust vent.
Soffit vents around the perimeter are not blocked allowing air to come into the attic from below the roof line and move up through the turbine vents to reduce moisture build up.
But some roof air vents sit fairly flat to the roof with a mushroom style hood and unprotected sides.
Power vents work a little better but they are much more expensive both in initial cost and in power consumption during their life.
It s the exact same process for a roof turbine vent.
The turbines are adjustable so that the spinning part is level even though the roof is slanted.

Not all turbines will fit all roof pitches.
The roof vent pipe is installed cut through the roof and around the pipe attached to the roof is surrounded with rubber boot as insulation for the gap between the pipe and roof.
Once again watch this video and imagine i m installing a turbine vent.
They have fins that open when they turn in the wind and this spinning action creates suction that draws hot humid attic.
Turbines work very well.
Roof turbine vents are leaking.
Flashing for the turbine looks ok standard flashing that comes with the turbine under the mineral cap roof.
The base flashing of the turbine vent is identical to the bath fan flashing you ll see.

And on occasion a hard driving rain with whipping wind will cause roof vents to leak water.
Most air vent styles prevent direct intrusion of water.
Good attic ventilation is important for preventing ice dams in the winter.

If you decide to add more turbine vents to your roof be sure to buy ones that are aluminum.
These will not rust.
In addition pay attention to the maximum roof pitch that will work with the turbines.
