Your HVAC unit works to make your home comfortable and cool by squeezing the humidity and heat out of the air. If your system is continuously struggling to cool your home, and your energy bills are skyrocketing, then your roof might be the one to blame. There are a few ways your roof can make your HVAC work harder than it is supposed to:
If you’ve ever worn dark clothes outside when it’s 90 degrees outside, you know how your dark roof feels. Darker colors absorb and hold in more heat compared to lighter colors. If your roof has dark asphalt shingles, then it will absorb and trap the heat in the attic space. Then from your attic, the heat presses into your living spaces trying to find somewhere else to go. As a result, your air conditioning unit works to try to keep your home cool.
One-way heat transfer
Heat will naturally transfer into your home through the roofing materials, causing your AC to work harder. Warm air can also build up inside the attic space from the outside temperatures. The best way to keep this from happening is to invest in new roofing materials. Your nest options is a roof that not only reflect the outside heat, but that will also release the heat that is trapped inside. Re-emissive metal roofs do both by releasing the absorbed solar radiation from your attic along with reflecting the sun’s rays on the outside.
Invest in a radiant barrier
If the ducts for your HVAC system have to run through your attic or a crawlspace, then a radiant barrier will help save you some money. Due to the exterior heat that is suffocating your attic, your ducts could lose cold air. When you get the right barrier installed on your ducts, the cooler air will remain unharmed by the heat. This will allow cold air to flow to the rooms you want it in.
Another thing to remember is to make sure that your attic ventilation is working correctly. If your ventilation is inadequate, then the heat will sit there. You can harm your HVAC unit this way, causing the need for an expensive repair or replacement. Your shingles may start baking from underneath and could crack.
