This summer has certainly had its share of heat waves. These high summertime temperatures often come with the urge to run the air conditioner at a constant rate in an attempt to keep the house at a comfortable climate. But after many HVAC inspections and service, the heat refuses to relent, leaving many homeowners to question whether or not their roof or attic insulation has something to do with the uncontrollable heat indoors.
If you have some doubts about your home’s roofing insulation, this article can help clear the air. Continue reading to learn what effects your roof’s level of heat absorption, and what you can do to ensure your roofing system is in quality condition.
Roofs can absolutely have an effect on the overall indoor temperature of a home. Let’s start with color. The darker the color, the more heat it will likely absorb. Dark asphalt shingles, tiles, metal, and similar materials attract more light and absorb higher levels of heat. In the winter, this level of heat absorption does not change, which is a good thing. But in the summer, a roof’ surface can reach up to 120 degrees Fahrenheit or more on 90 degree Fahrenheit day.
Excess heat will travel into the attic or upper areas of the home, and eventually transfer into the living quarters, thus affecting the indoor climate and even monthly energy bills. Lighter roofing materials are more reflective than absorptive. They retain less light and heat, thus delivering steadier indoor temperatures on hot days. Regions that experience heavier or regular snowfall generally have darker roofs, while hotter regions generally have lighter roofs.
The type of roofing material can also influence the amount of heat and light absorption. For instance, asphalt shingles reflect an average of 30% of light that comes into contact with a roof, while metal panels are more reflective and absorb less heat. There are various types of roofing materials, all of which offer their own unique heat absorption and light reflective properties.
Energy Efficient Options
It is important to choose the right material for your home that can also meet your energy efficiency needs. One way to do this is to inquire about cool roof technology, which are specially designed to absorb less heat and reflect more light compared to standard roofing systems.
Another option is to have your roof and attic insulation and ventilation upgraded or serviced. Start by contacting a trusted roofing company for a comprehensive inspection. They can provide the right information and recommendations necessary to meet your home improvement goals.
