Attic Insulation & Ventilation

Have you ever found yourself wondering should my attic be vented? Rest assured, it’s a question we get with surprising regularity, and for good reason. The easy answer is yes, your attic should absolutely be vented. But when it comes down to it, it can get a little complicated. Each home is unique, carrying challenges and structural requirements to match. To get down to brass tacks, the question becomes less about should you and more about how much you need.

Too Much of a Good Thing

Proper ventilation is integral to helping lower moisture levels in your attic, a problem that plagues the vast majority of homes across the country. Moisture collecting in your attic can lead to a slew of issues, including rot and, if you use the space for storage, damage to your possessions. It can also damage and rot out your insulation, which in turn can quickly cascade into even more problems (read: even more money).

So, with all of this in mind, you may be thinking you can’t get enough ventilation, right? Nope. Just as you need to properly size your air conditioning and heater to your home, so too do you have to ensure you have a proper amount of ventilation. Contacting a professional to get a consultation is really a must, as only they can gauge your attic’s needs. Proper ventilation is about striking a balance, and if it goes out of balance, it may as well not be there at all.

Myth: Ventilation Leads to Higher Energy Use

The idea that ventilation lets your temperature controlled air out of the house, and spikes your bills is an unfortunate fallacy. In actuality, a properly insulated attic should pretty much exist independently of your home in the temperature department.

With proper insulation, you can basically think of your home as a sealed box, and the attic exists outside of this box. This myth can actually cost a misled homeowner more in the long run, if they were avoiding looking into appropriate ventilation for fear of crushing heating bills.

The most energy-efficient attics are insulated and ventilated. Even if your attic has insulation, you may still be asking “So, should my attic be vented, then?” and the answer is probably yes. There’s a chance it already is, but it’s always best to reach out to a local professional for the final word if what you have is enough (or too much!).
