For a roof to remain healthy and function as intended, it is essential to have a ventilation system. Without proper ventilation, an attic can develop mold and trap heat within. Along with that, choosing a licensed contractor can go a long way in ensuring that you can fix any problems down the road. Let’s learn in detail about attic ventilation and its benefits. 

What Are the Advantages of Attic Ventilation?

Saves Energy

When the temperature rises in the summer, air conditioners are used to cool down the house. As the cool air fills the home, the hot air needs space to escape. Ventilation plays a major role in this. Your air conditioner can lower energy consumption if the hot air has somewhere to escape. Consequently, your utility bills will go down. Proper ventilation in your home, especially in the attic, is a good step in saving money.  

Lowers Indoor Temperature

As the air in your home rises up, the lack of ventilation will cause it to remain there, making the house warmer. This is also the reason the upper floors of most homes are warmer than the lower levels. Proper ventilation will prevent this discrepancy in temperature. 

Increases Roof Life

It is common to see icicles on your roof during the winters when it is snowing. If your roof is unvented, the snow will slide off to the end as a result of the attic’s trapped heat. The snow will then refreeze there, causing icicles. A properly ventilated roof will prevent ice from forming on your roofs because the air can escape, allowing the snow to sit on the roof and melt naturally. While icicles on the side of the roof look pleasing, they add unnecessary weight to your roof and can cause a lot of damage over time. You can prevent this damage and elongate the life of your roof by installing the right ventilation. 

What Amount of Ventilation Is Needed in an Attic?

A roofing professional can measure and tell you how much vent area you need, but a general rule of thumb would be that for every 150 square feet in your attic, you need 1 square foot of vent area.

How Effective Are Ridge Vents?

When installed at the peak of the roof, vents are an excellent option for their effectiveness. In this way, warm air can escape from the attic.

Is It Possible to Over-Vent an Attic?

If you add too many vents to your roof, you may end up overdoing it. It is essential to maintain the same types of vents on your roof and seek a professional’s help in doing it. MCM Home Exteriors can be your guide when it comes to attic ventilation, roofing and other home exterior installations, maintenance services and repairs.
