Roof hot air extractors.
Roof ventilators are designed to help exhaust contaminated air from kitchen range hoods up and away from the roof.

Start in the attic and drill a hole through the roof in the desired vent location.
Leave the drill bit sticking through the roof so you can find the hole.
Since hot air rises to the ceiling or the highest point of a structure it makes sense that having exhaust fans mounted on the roof will work best.
