turbine roof vents problems

If you have a turbine roof vent installed on your roof, you might already know the advantages it brings, like increased ventilation and energy savings. But, like any mechanical system, turbine roof vents can run into problems over time. In this guide, we’re going to dive into turbine roof vent problems and offer practical solutions to help you address them effectively.

Understanding Turbine Roof Vents

Turbine roof vents problems

Before we roll up our sleeves and tackle these issues, let’s quickly brush up on turbine roof vents and how they work. A roof turbine vent is a type of exhaust vent that plays a key role in controlling the temperature and moisture levels in your attic. It’s made up of a bulb-shaped fan with propeller-like blades that spin when the wind blows, creating a vacuum effect. This, in turn, whisks away hot air from your attic and lets fresh air take its place.

These vents offer many benefits, including improved air circulation, reduced moisture buildup, and savings on your energy bills. They work wonders in places where there is ample wind, on both flat or sloped roofs.

Problem 1: Inconsistent Rotation Speed and Ventilation

One common problem with wind turbine roof vents is their inconsistent rotation speed, which affects ventilation. These vents rely on the wind gusts to spin their propeller fans and circulate air. But when strong winds or storms come along, they might kick into overdrive, causing too much airflow and major fluctuations in your attic’s temperature and humidity levels. On the flip side, in areas that only receive a mild amount of wind, these vents might not work as efficiently, which can lead to less airflow and more moisture in your attic.


  • Optimal Placement: To ensure the vent is working properly, install your turbine vents along the roof’s peak or on the windward side to maximize airflow. 
  • Wind Barrel or Vent Cap: A wind barrel or vent cap can help slow down ventilation during extremely windy days.
  • Battery Backup: In regions where the wind is not consistent, consider using batteries to keep the fan turning and ventilation flowing.
  • Vapor Barrier: Adding a vapor barrier in your attic can help you fine-tune the speed of those vents and keep more warmth in when needed.
  • Sealing and Moisture Control: Seal gaps or cracks in your vents with roofing cement. Doing this not only improves moisture control, but also keeps leaks at bay.

Problem 2: Weathering and Rusting of Vents

Turbine vents protect your home from a number of issues by standing up to all kinds of weather. But that constant exposure can take its toll, leading to turbine roof vent problems. Continuous use and sunlight can cause the vents to wear down. When that happens, you might start hearing noises, feeling vibrations, or even notice damage to the shingles nearby.


  • Protective Coatings: Shield your vents with enamel or anti-rust solutions to stop corrosion in its tracks. You can also add grease or machine oil for smoother operation.
  • Dehumidification: Installing a dehumidifier below the vent will help prevent excess condensation and dampness.
  • Noise and Vibration Reduction: Add insulation to your vent to muffle the noise and vibrations caused by wind or mechanical movement.
  • Moisture Control: Using a vent cap will help prevent moisture-related damage.
  • Shingle Maintenance: Regularly check and seal any shingles around the vent that look warped or discolored. This helps minimize water damage.

Problem 3: Vent Moisture and Leakage

Another common problem roof turbine vents face is moisture buildup and leaks. Loose connections, gaps, or broken fasteners can let rainwater sneak into the vents, potentially causing water damage and leaks.


  • Rust-Proof Fasteners: Use nails and screws that won’t rust to secure the vent, making sure to tighten them well to minimize gaps.
  • Sealing and Waterproofing: Give your vent extra protection by adding caulk and roofing cement to create a water-tight seal. Roof flashing can also help with moisture control.
  • Blade Maintenance: Keep the vent blades in top shape by coating them with oil.
  • Durable Caps: Use a sturdy metal or PVC cap to prevent the blades from bending, and to ensure they last for years to come.
  • Attic Inspection: Regularly check the paint in your attic for peeling or blistering, as this could be a sign of moisture sneaking in.

Problem 4: Insufficient Airflow and Ventilation

Sometimes, your turbine roof vents might not be operating as they should, especially in areas with low wind or if they weren’t installed correctly. This can mean your attic isn’t getting the airflow and ventilation it needs, which can disrupt the temperature regulation.


  • Proper Placement: Make sure your turbine vents are placed where they’ll get the most wind and airflow
  • Additional Vents: If your attic is still feeling stuffy, consider adding more vents or trying out different ventilation systems to move the air properly.
  • Professional Installation: If you’re unsure about the installation process, it’s a good idea to bring in a professional to ensure everything is set up perfectly.

Problem 5: Improper Installation of Turbine Vents

Incorrectly installed turbine vents can cause a whole bunch of problems, from increased noise to inefficient ventilation. Common installation slip-ups include putting them in the wrong place, not sealing them properly, or just not lining up the pieces correctly.


  • Follow Manufacturer’s Instructions: Take a good look at the instructions that come with your turbine vents and follow them carefully.
  • Professional Assistance: If you’re not feeling confident about the installation process, call a professional for help. They’ll make sure everything is level, sealed, and aligned just right.
