Proper attic ventilation is essential to your roof, an important requirement for preventing the need for unnecessary roof repair. Fortunately, there are a number of different vents that roof companies can install on your home to promote good attic ventilation, including turbine vents. When properly installed by roof services as part of a complete ventilation system, turbines can increase the ventilation of your attic, making it easier to keep that important space and cool dry.
What Are Roof Turbines?
Roof turbines are a type of air vent that roof companies install near the top of your house to improve attic ventilation and airflow through that space. Turbines are made of lightweight metal and comprised of a circular unit containing spinning vanes that rotate when blown by the wind. They are available in a number of sizes and finishes to serve various needs.
Roof services typically install turbines on homes that require additional ventilation to improve the efficiency of existing ridge and soffit vents. Turbines can also be a good solution to increase ventilation for homes that do not have ridge vents. They are quiet, efficient, and very effective in releasing hot air and moisture as well as preventing costly roof repair due to ventilation problems.
How Do Turbines Work?
Turbine vents installed by roof companies are wind-powered, requiring no electricity to run. When the wind blows and turns the vanes, attic air is drawn up into the vent and exhausted outside the house. The faster the wind turns the vanes, the greater the flow of hot air out of the attic. Turbines also allow rising, hot air to escape the attic even if there is no wind turning the vanes.
Additionally, when the vanes are in motion and the turbine is drawing air out, the intake of air through the soffit vents and further ventilation through the ridge vents is improved.
Does Your Roof Need A Turbine?
Standard roof ventilation consists of ridge vents that release rising, hot air out of the attic and soffit vents that allow fresh air in to replace what has escaped through the ridge vent. Roof services find that for most homes, this system is sufficient to keep a good balance of inflow and exhaust so the attic remains cool and the continual air movement prevents condensation.
When the ridge and soffit system is inefficient or there are no ridge vents, hot and moist air stays trapped in the attic. This increases cooling costs and allows condensation to form. Over time, unvented heat and moisture can cause a number of problems with your roof resulting in a need for expensive roof repair. Turbine vents provide the perfect solution to this problem since they increase ventilation, promote the movement of air in and out of the existing vents, or provide essential ventilation where there are no vents.
The best way to find out whether you should consider having a roof company install turbine vents in your home is to arrange for an inspection of your roof and attic. Roof services will measure the amount of air that flows through your soffit and ridge vents, looking for signs of poor ventilation and determine whether a turbine vent or two would be beneficial. Inexpensive and easy to install, turbine vents are a great solution to reduce your cooling bills and prevent damage that requires expensive roof repair!
