How Does Your Roof Affect Your Home’s HVAC System?

Your HVAC system works hard in the warmer months to keep the heat and humidity out of your home. When your bills are higher than expected, it’s easy to blame the weather, or the HVAC system itself. However, your roof does affect how efficiently your HVAC system will perform. If your roof is old, a quality home roof replacement with good roof insulation may have the added bonus of helping your HVAC system function more efficiently.

How Your Roof Affects Your HVAC

Heat naturally transfers into your home through your roof. Certain roofing materials absorb more heat in the warmer months, making your HVAC system work harder to cool your home. A roof covered in dark asphalt shingles will absorb a large amount of heat into the attic space, which will then press down into the living areas of your home, forcing your system to work harder to cool the air. Your system will have to run more often to keep up and maintain a comfortable temperature.

Looking in Your Attic for Answers

Checking your attic is a good first step to know if your roof is to blame. If your attic is oppressively hot in the summer, that heat is being absorbed by the roof shingles and is pressing down into the rest of your home. If your HVAC ducts are in the attic or a crawl space, the heat coming in from the roof is causing those ducts to lose the cold air before it can make it into your home. Installing a radiant barrier on your ducts can help as it will allow more of the cold air to remain intact, which in turn is delivered to the rooms in your home.

How a Home Roof Replacement Will Help Your HVAC Performance

To help your HVAC system, a home roof replacement with the right materials will make a big impact. There are colors and shingles designed to reflect heat, rather than absorb it, which will help your home stay cooler in the summer. Lighter colors or reflective metal can help deflect the outdoor heat, helping your attic, and the rest of your home, stay cooler. These materials can be a higher initial cost during replacement, but will help to lower your energy bills, saving on monthly expenses in the long run, and that’s good news for your monthly budget.

A home roof replacement is a significant investment, but when your roof needs replaced, the smartest thing you can do is invest in a quality replacement. Replacing your roof isn’t something you want to do again any time soon, so the roofing materials you choose will need to be built to last. Choosing materials with your HVAC system in mind may save your energy bills from skyrocketing through the seasons, too.

Quality of Installation

Choosing the right materials for your new roof is important. Hiring an experienced, qualified roofing contractor is worth every penny. You can choose the best materials, but if they’re improperly installed, the product won’t last. Unfortunately, sometimes bad roofing jobs aren’t noticed right away and that can make things complicated down the road. Do your homework when looking for a contractor to replace your roof.
