For many homeowners, their attic isn't a place they think about often. At best, it's a place to shove holiday decorations and outgrown clothes until someone needs them.
It's not surprising, then, that homeowners don't think about how well air ventilation works in their attic. If it's rare for anyone in the family to go up there, why worry about whether the air is moving?
The truth is, poor air ventilation in your attic can cost you both comfort and money. That's why it's important to make sure you have proper attic ventilation and to keep it maintained through the years.
How Does Hot Air Get to Your Attic?
Hot air is lighter than cool air. As a result, it rises as high as it's able to rise. If you picture your house, the highest point is most likely your roof. Since your roof is designed to keep the weather out of your home, it's pretty good at stopping most of the air that floats up to it.
The air in your home gets hot in several different ways. Sun from the windows, warm air coming in from outside, and the heat from cooking, electronics and showers all work together to warm the air. As it warms, it rises. Some air collects under the ceilings in each of your rooms, but more continues up to collect under your roof in your attic.
Why Do Attics Need to Be Ventilated?
In terms of comfort, having the heat go up to your attic sounds good at first. At least it's not down where you live, right? The problem is that without proper attic ventilation, most of the hot air stops under your roof. As more hot air goes upward, it stacks below the air that's already there. Once all the attic air is heated, the rooms below it begin to feel the heat, as well.
In terms of cost, the extra heat that's trapped inside your house forces your air conditioning system to work harder. As a result, your energy bill is higher than it should be.
All the extra heat and lack of air movement in the attic can indirectly cause structural issues, adding to your costs over time. Lack of attic ventilation can lead to problems such as:
- Excess moisture that creates a good environment for mold and wood rot
- Expansion and contraction of wood that damages your subroof and shingles
- Ice dams in the winter that can cause water damage when they melt
- Fixing an Unventilated Attic
The good news is that these problems can be avoided by fixing the ventilation issues in your attic. Correctly placed vents release hot air through the roofline while cooler air comes into the attic through the soffits. An attic fan can go a long way toward keeping air flowing properly.
