Aluminum roofing is exceptionally reflective, even more so than other kinds of metal roofing. Reflection isn’t just about light, the same principles apply to heat. Much of heat energy actually travels like a wave, meaning that a reflective material can effectively redirect it back to where it came from. Aluminum reflects roughly 95% of all energy that strikes it, making it very effective at this task. This will be a great help to your home in any season.
In winter, most of the heat energy comes from within the home through whatever heating unit may be there. Whether a modern heater or a fireplace, the energy behaves very similarly. As this energy tries to escape the home through the roof, the aluminum roofing material will reflect it back inside. This means that less heat will escape the house. The less heat that escapes, the less new heat that needs to be generated. This equates directly with lower energy costs.
In the summer, most of the heat energy comes from outside of the home, typically from sunlight which strikes the roof. Since aluminum reflects most of the sunlight away, it doesn’t enter the home. Contrast this with conventional roofing material and you’ll see a big difference. Many other kinds of roofing actually absorb this solar energy, making your home warmer! Aluminum roofing reduces the energy that enters your home, meaning that there is less for your AC to do. This reduces your electricity consumption, making your energy bills substantially lower.
No matter what the time of the year may be, aluminum roofing will work to reduce the total cost of your energy bills.
