Attic ventilation is highly important for the lifespan and durability of the roof. A good attic ventilation system can ensure a long lasting and durable roof. Whereas a poorly functioning attic ventilation can result in the appearance of damages in the roof. Attic ventilators are extremely critical for the proper functioning of the building and the roof as well. The attic ventilators work on the principle that the cool air comes in and hotn air goes out. This causes the maintenance of optimum temperature in the building, without letting the hot air get in and always bringing a cool and moderate air temperature into the building. The attic ventilation system comprises two parts.First part is intake vents, which are located at the bottom part of the roof. These intake vents allow cool air to enter the attic.The second part is hot air exhaust vents, which are situated at the top part of the roof.These exhaust vents allow hot air to escape.This process is known as passive ventilation and is very advantageous and beneficial for the maintenance of proper temperature in the building.To make this process even more effective and functional it is always advised by the contractors to install these vents at least 1 sq. ft. of vent for every 300 sq. ft. of attic floor. This can vary from building to building but these measurements should be kept in mind while installing the vents.Proper installation of these vents is extremely important for successful ventilation. For this reason it is very important to hire highly professional roofing contractors queens, ny who are qualified enough about these events.
Considering the importance of attic ventilation, there are some misinterpretations and misconceptions made on the basis of assumption by many amateur roofing contractors. These misconceptions are highly misleading to the building owners. So to make our readers more informed, we are listing down the most common misconceptions regarding the attic ventilation.
● The more the better !
It is usually considered that by adding a large number of vents into the roof, the ventilation process would enhance in efficiency. But that is highly untrue,this is because adding more vents would create too much ventilation. Moreover adding vents means more penetration in the roof. This excess penetration due to addition of excess vents can lead to leaks during storms and hurricanes. Therefore in this case moderate is better, not more.
● Not suitable for cold climate:
It is usually a misconception that attic ventilators only help during the summer. During summer it helps financially by reducing energy usage and thereby reducing expenses by maintaining a cooler temperature. But attic ventilation is also highly important during the winter as well.As during winter it prevents the moisture damage in the attic, which prevents leaks and condensation on the roof sheathing.
● All vents are same:
Another myth regarding the attic vents is that all the vents are the same and function exactly in the same way. It is thought that any building would go with any kind of vent regardless of the type or building and vent. But this is not true, as one vent type may be suitable for one building but not for the other one. For example, ridge vents are highly affordable and provide good ventilations as well. On the other hand gable vents are best suited for ventilation in smaller spaces. Static roof line vents are extremely functional but there is a risk of leaks in such vents. When it comes to soffit vents they accumulate air inside the attic. So different vents have different qualities, it depends on the building type and requirements to choose what type of vent is best for you.
