Important Tips for Proper Attic Ventilation

Unless you get into the attic and visualize what’s up there, chances are, you don’t give much thought about things like insulation and ventilation. Even though most of what happens in the attic is sight unseen to homeowners, it’s important to be aware of how well your attic is ventilated. On one hand, you should have a good understanding of what’s needed, but on the other, be careful not to be swayed by extreme opinions. Here are a few tips to help you determine what steps you can take to ensure proper ventilation, and a few cautions to consider.

What’s the Point of Ventilation?

The answer to this question depends in part, on where you live. For example, if you live in a part of the country where summers are extremely hot, attic ventilation is needed to vent hot air from the attic. This results in a decrease of energy required to cool the home. Homes in cold climates need a way to keep roof temperatures cold enough to control ice dams, which are hunks of ice that are found on the roof’s margins. When temperatures warm, melting water from the roof dams up behind them. If left to its own devices, the water can back-up several feet under the shingles. You can imagine what disasters are avoided with proper attic ventilation.

How Much Ventilation Do I Need?

The short answer to this question is that every 300 square feet of ceiling space requires 1 square foot of attic ventilation. Other factors may change those numbers. For example, the number of vent grates installed on the roof reduces the area needed for ventilation. The average homeowner doesn’t know how to accurately calculate for the required attic ventilation. Rather than agonize over it and end up making mistakes, your best option is to call a roofing professional. A roofing company employs people who are trained to know how much ventilation your home needs. If you’re truly curious how they come up with their calculations, ask. Most roofing professionals are happy to discuss the job with the homeowner and can explain things in layman’s terms.

What about an Attic Fan?

Attic vent fans are designed to decrease attic heat by drawing in cooler outside air from attic vents and pushing hot air to the outside. When you’ve installed an attic fan, you may notice a difference in the heat you feel at the ceiling level of your home. If more efficient cooling by your air conditioner is what you’re looking for, you might consider installing one or two attic fans. Before installing an attic fan, consult with a roofing company as it’s important to make sure you’re installing the correct size. If you don’t, you run the risk of installing a fan that won’t move enough air to have the cooling effect you need.
