Roof turbines aren’t decoration for your roof but are components of a passive ventilation system that is extremely important for your home. Here are three important facts you should know:

  1. Roof turbines pull humid air from the inside of your attic and release it outdoors. By removing attic moisture, turbines reduce the risk of mold, mildew and wood rot. Without turbines, moisture from the home can drift into the attic space and condense on the framing of the roof and beneath the sheathing. In winter, if this situation increases, frost can actually build inside the attic.
  2. Newer turbines are made of aluminum and are mostly rust and tarnish resistant. However, flying debris, large hail or heavy winds can damage the turbine and interfere with their function. If you here a rattle on your roof, it could indicate that your turbine needs to be lubricated or repaired. If your roof has damage from severe weather, it is very possible that your turbines will have damage, also. Fortunately, a qualified roofing contractor can make the repairs very easily.
  3. Turbines are powered by mother nature and use wind to incite the spinning action.  This not only makes them in-expensive, but also helps increase the energy efficiency of your home. They are often used in conjunction with intake vents to properly vent your home.

Part of maintaining the health of your home includes making sure that all roof elements function properly. If you notice moisture buildup in your attic, or hear a rattle from your roof, then your roof turbines may need to be inspected. Turbines are built to last, and unless they sustain significant damage should last the lifetime of your roof.
