How Your Roof & Attic Affect Your Air Conditioning

air conditioning experts

Our air conditioning experts know it’s been a hot summer so far. If you’ve found yourself struggling to keep your home cool, you may be in need of a new air conditioner. However, if your air conditioner is working properly and is fairly new, the culprit may actually be your roof. Here’s how your roof and attic can affect your air conditioning quality:

Dark Colors

If you have a dark colored roof, it may actually be absorbing the heat from the sun (much like when you wear a black t-shirt on a sunny day). This absorbed heat is then transferred to your attic and if your insulation isn’t up to par, the heat will transition down into the rest of your home. This means your home will be warmer than it should be and in return, your HVAC unit will have to work harder than it usually does.


If you’re in the market for a new roof, you may want to consider one with lighter colored shingles to help reduce heat absorption. If you’re not in the market for a new roof, however, the next thing you can do is make sure your attic has the proper insulation.

Insulation isn’t just used to keep homes warm in the winter – it plays a part in keeping homes cool, as well. If you don’t have enough insulation in your attic, it won’t trap the heat and will allow it to move to the rest of your home. In addition, if your ductwork passes through the attic, the attic heat could reduce how cold the traveling air is. Once the air gets to your vents, it won’t be as cold as it should be.


Attics are designed to stay cool by pulling fresh air in through the eaves and releasing it through vents in a higher area. If your ventilation system is blocked or isn’t working properly, it will be harder for your attic to stay cool and in turn, harder for your home to stay cool. Have a home improvement professional inspect your attic and make sure it’s designed for good ventilation.

If none of these things seem to be the problem in your home, your HVAC system may be at fault. Contact our air conditioning experts to schedule an inspection. We’ll make sure your system is doing its job.
