The cooler a roof, the less radiant heat it emits. While the roof absorbs radiant heat from the sun, airflow (wind or attic ventilation) cools the roof, helping to lower the overall temperature. Secondly, air temperature and wind movement over and beneath the roof impact the temperature. Dark-colored roofs can be over 20✯ hotter than light-colored ones. If you are worried about your shingles overheating, the color of your roof is the greatest priority. Two main factors determine the highest temperature a roof will reach: color and ventilation. Many regions even mandate radiant barriers for new construction due to the energy savings they produce. Most shingle manufacturers offer warranties for their products over a radiant barrier. Standard roofing systems can handle temperatures significantly higher than what they actually reach in real-world situations. A roof equipped with a radiant barrier will experience a temperature rise of only a few degrees (typically between 2º and 10º degrees Fahrenheit). Will a Radiant Barrier Cause Shingles to Overheat? In this section, we will explore these concerns and discuss how they can be addressed. Additionally, there are concerns about the effect of radiant barriers on shingle manufacturers’ warranties. Some homeowners worry that installing a radiant barrier may cause the roof to get hotter, leading to potential damage to roof shingles. Will Your Shingles Survive a Radiant Barrier?

Improved energy efficiency: Radiant barriers can reduce the amount of heat transferred into your home, leading to lower energy costs. Homeowners will enjoy several advantages from a professionally installed radiant barrier in their attic, including: Installed correctly, they can make a significant difference in your home’s energy efficiency and indoor comfort. These barriers work by reflecting radiant heat back, preventing it from entering your living space. Common materials used in radiant barriers include foil-faced plywood, reflective foil insulation, and radiant barrier paint. Basics of Radiant BarriersĪ radiant barrier is a type of insulation designed to reduce heat transfer in your home. In this article, we will discuss the benefits of radiant barriers and address these concerns to help you make an informed decision.
