Your Roof’s Impact on Your HVAC System

September 14, 2019

Your roof is your home’s first defense from the elements, including the hot Texas sun. However, it can also have a major impact on the efficiency of your home’s HVAC system. If you are constantly battling extremely high energy bills each month, your roof could be part of the problem. If your attic is not properly sealed and insulated, the heat that builds up in it seeps into your living space. That means your HVAC system needs to work harder to keep your home cool and comfortable. And that also means more wear and tear on your system that could lead to a shortened lifespan.

Roofing Factors to Be Concerned About

Roofs that are covered with dark-colored asphalt shingles will absorb a lot of heat. The problem is that many homes have this type of roof because it is a very affordable roofing option. However, the trade-off in savings is that the heat needs to go somewhere, which is typically the attic.

Attics need to be properly ventilated to prevent heat buildup. Proper airflow will help dissipate the hot air and prevent it from affecting your HVAC system. Heat buildup can damage your roof and shorten its lifespan, too.

How You Can Protect Your HVAC System?

It is possible to reduce your roof’s impact on your HVAC system and cut your energy costs. If you plan to replace your roof soon, you can lessen its impact by choosing a reflective roofing material. A metal roof will give you the most reflective capability. If you prefer shingles for your home, modern shingles now have a reflectance level of at least 0.25 or more. You should also look for roofing materials that have at least a 0.85 emittance value. The higher the emittance value, the more heat these materials will release.

Attic Insulation and Sealing: Your Best Defense

Your best defense against heat from your roof seeping into your home is a properly sealed and insulated attic. If investing in a roof replacement is not in your immediate future, insulation can help keep the heat out of your living space. This helps keep your home cooler and takes the added stress off your home’s HVAC system.
