Roof ventilation comes in various forms including turbine vents, low profile vents, and ridge vents. It lowers the temperature and removes moisture from the attic, helping roofing materials last longer. Solar powered vents and skylights are also available. Different types of vents suit different roofing types and design choices.
Roof ventilation, also known as attic ventilation, comes in various forms. Consisting of intake and exhaust vents, the basic roof vent system can be found in a few forms including turbine vents, low profile vents, and ridge vents that they are specially designed to fit specific roof shapes. Solar powered energy efficient vents and skylights are also available.
An important covering element, the ventilation system lowers the difference in temperature between the attic and the outside air. Moisture and heat are removed from the attic, putting less stress on the roof and helping roofing materials last much longer. Accumulated moisture can cause enough damage that the roof may need to be replaced. Parts of the roof and items stored in an attic are easily damaged in temperatures up to 150°F (65.5°C), which occur within inadequately ventilated attics.
One type of roof ventilation is the turbine vent. A rooftop turbine, also known as a rotary vent, has a whirligig that serves as the exhaust mechanism. It is affected by the wind, but the wind doesn’t need to blow for the unit to work. This type of vent is high-profile, and while considered very effective, it’s not always a desirable choice.
While the rooftop turbine has a more protruding design, there are various choices for low-profile roof ventilation. These are generally less expensive and come in materials such as steel, plastic and copper. Various shapes and styles suit different roofing types and design choices.
Another form of roof ventilation is ridge ventilation, which is suitable for pitched roof systems. This type of system consists of a vent and ridge that install along a slot that is cut along the ridge of the roof, forming a continuous ventilation system. It can come in a shingle design to match the roof shingles, while there’s also a system with a one-piece vent and ridge that installs along the ridge of the roof.
More modern forms of roof ventilation include the solar attic fan, which is basically a fan with a solar panel attached to it. Power and cooling costs are saved when using such a system. Skylights also provide natural light that can heat the home economically and include vents that can offer sufficient roof ventilation. Depending on the type of roof you have and your style preferences, there are usually a few choices to consider for roof ventilation.
