What comes to mind when you think of maintaining an energy-efficient, comfortable, and safe home? Chances are, you thought about your gas line, electricity, and windows or doors. However, what if I told you that having proper ventilation in your home was crucial, not only for protecting your home, but for protecting everyone in it? In this blog, we’re going to talk a little bit about ventilation in your home and generally, what impact it will have on you and your family.

Attic ventilation

It’s easy to forget about your attic. You most likely just put your unused things there and don’t return unless you need to grab something. However, your attic ventilation plays a crucial role in keeping your home in good condition by protecting your roof, gutters, and helps you save money on energy bills. More specifically, proper attic ventilation will prevent ice dams. These occur when the bottom layer of snow and ice on your roof are melted by the temperature in your attic. So, what’s the problem if it’s melting ice, isn’t that a good thing? Well, not really. After the ice melts, it will run down the eaves and can refreeze, leading to damaged shingles, gutters, or decking.

When it’s hot out, poor attic ventilation will result in extreme temperatures that can lead to damaged roofing and lead to higher energy bills as your AC attempts to account for the added heat.

How to spot it

If you want to prevent poor ventilation in your attic, you’ll need to know how to spot it if it ever becomes an issue. Start by taking a walk around your home and inspecting the vents. Most attics will have a vent at the eaves to take in air, while it’s being pushed out at the top, through either the roof or ridge vents. If they are blocked or clogged in any way, you’ll want to remove whatever is obstructing them so that your attic can remain properly ventilated and prevent damage to your home.



Another way you can tell that there’s a ventilation issue is if you’re experiencing higher energy bills or notice that your fan is running too often or too hard. This could be anything, so you may want to first inspect your HVAC system or call an HVAC specialist to see if there is another issue that’s resulting in higher energy bills. Otherwise, it could be a ventilation issue. If it is, you’ll not only have higher energy bills, but your upstairs rooms will be hot and stuffy in the summer and in the winter, ice dams will form and snow will start melting in the middle of the roof, rather than at the eaves.

Additionally, during colder months of the year, heat from other areas of your home will rise and will find its way to your attic. If it isn’t ventilated well enough, this will result in condensation that can lead to mold growth and will damage your attic insulation and other parts of your home.
