Should I cover roof turbines in winter? You should absolutely leave your roof vents open during the winter – do not cover them! During the winter, roof ventilation works to keep temperatures even. Closing your vents makes the attic space too warm and dry – dangerous conditions for mold as well as pests.Roof turbines, also known as wind turbines or whirlybirds, are a popular and effective way to ventilate homes and other buildings. They work by harnessing the power of the wind to pull stale air out of the building and replace it with fresh air from outside. However, many people wonder whether they should cover their roof turbines in the winter months to prevent heat loss and reduce energy costs. The answer to this question depends on a few factors, including the climate in which you live, the type of roof turbine you have, and your energy goals. In general, it is not necessary to cover roof turbines in the winter, and doing so could actually be counterproductive. One reason why covering roof turbines in the winter is not necessary is that they are designed to work in all weather conditions. High-quality roof turbines are built to withstand strong winds, heavy rain, and snow. They are also designed to prevent snow and ice from accumulating on the blades, which could cause them to stop spinning. Another reason why covering roof turbines in the winter is not necessary is that they can actually help to reduce energy costs. In the winter months, warm air rises to the ceiling of the building and can become trapped there, creating a layer of hot air that can be uncomfortable and expensive to heat. By using roof turbines to pull this warm air out of the building, you can create a more even temperature throughout the space and reduce your heating costs. However, it is important to note that not all roof turbines are created equal. Some lower-quality models may not be able to withstand harsh weather conditions or prevent snow and ice buildup. If you are concerned about the performance of your roof turbine in the winter, it is important to consult the manufacturer's instructions or consult with a professional to ensure that your turbine is properly installed and maintained. In conclusion, there is no need to cover roof turbines in the winter months. These devices are designed to work in all weather conditions and can actually help to reduce energy costs by improving ventilation and temperature regulation. However, it is important to ensure that you have a high-quality roof turbine that is properly installed and maintained to ensure optimal performance in all weather conditions.
