Found in the Field…One roof repeating the same big mistake several times. Mixed types of attic exhaust vents. Pick the most suitable TYPE of attic exhaust for the roof (wind turbines or power fans or gable vents or box vents/off-ridge vents or power fans) and run with it. Mixing types causes inefficient airflow and could invite weather infiltration. Thanks for finding and sharing this, Trevor Atwell, Atwell Exterior Services, Greenville, NC.
