There are many roof ventilation systems available today, depending on the type of roof that you have. Non-experts may find the information overwhelming and can become confused or frustrated. It can be difficult to know when and where ventilation should be used, which type is best for your roof, and what the reason behind it all is. Let’s talk about roof ventilation and how it applies to different types of construction.
Why Ventilation is Important?
Roof ventilation works by controlling temperature. It helps prevent ice dams in cold climates by keeping the roof cool and allowing moisture to escape from conditioned living areas through the attic. Proper ventilation, on the other hand, allows solar-heated heat from the attic to escape in hot climates. This reduces a building’s cooling load while limiting the strain on air-conditioning systems. In regions with extreme climates, roof ventilation can serve both of these roles.
Types Of Roof Ventilation
Depending on your area’s building codes, you will likely need one square foot for every 150 square feet. Ventilation is not just for air escape but also to allow air to enter. There are many types of ventilation. We will now discuss them.
- Box vents can also be called louvers, flat vents, or turtle vents. Because they don’t have moving parts, they are called static vents. Box vents are designed to cover a hole in the roof. They use natural convection for air movement and provide ventilation. Box vents come in many colors and can be made from a variety of materials. They are versatile and inexpensive and are one of the most popular types of roof ventilation systems.
- Whirlybirds are also known as wind turbines. Although they have moving parts, they don’t have a motor. Instead, they rely on the wind to drive their movement. These ventilation systems are more efficient than traditional box vents, provided the wind blows.
- Power vents combine the best of both box vents as well as wind turbines. They are motor-driven, so they can provide proper ventilation no matter what the weather or wind conditions. They are more efficient than box vents and whirlybirds, but they are still quite effective.
- Another type of static vent system is the ridge vent. They are installed on roof ridges. These vents are attractive because they can run the entire length of a roof’s horizontal roof ridge and blend seamlessly with the roof’s design, making them an appealing option.
- In that they are static vents, off-ridge vents look similar to box vents. They are usually installed on a cut section or roof near the ridge. Box vents are rectangular and square, while off-ridge vents can be narrower and more efficient.
Roof ventilation systems can be complex and varied. As such, it is important to consult a professional roofing contractor before deciding which roof ventilators Connecticut system is right for you. Your contractor will be able to tell you which system is best for your climate and what type of roof.
