Reflective roof coating has the power to reflect the sun’s scorching heat back into the atmosphere and keep the inside of the building cooler without the need to turn your air conditioner on. Good quality roof coatings can reduce roof temperature by up to 50 F and also improve the overall indoor environment.
Roof coatings are available in various shapes, sizes and colors that not only helps to reflect sun’s solar heat but also enhance the beauty of the roof and extend the lifespan of the roof.
Reflective coating sure aids you in decreasing the energy costs of your home, however, there are certain factors involved that determine the amount of energy to be saved. These factors include shape and size of the reflective roof coating, type of coating you pick, how much energy is being used in your home and the local climate of your area.
A good reflective roof coating can save up to 70% energy. Areas that experience a hot climate and scorching heat of the sun directly falling on the roofs of the houses must opt for reflective roof coating. Even if you live in a region that does not get much sunlight, you can still enjoy the benefits of such roof coating as it reduces overall energy cost by at least 20% during average temperatures.
Reflective Roof Coating Helps You In Two Ways
You can benefit from the reflective roof coating in two ways. One, solar reflectance, the heat is prevented from entering your home, thanks to reflective roof coating. The surface of this coating has the tendency to reflect the light and pass it back into the atmosphere, therefore, the temperature in the house doesn’t exceed much and you may not require to turn on your air conditioners 24/7, thus energy is saved.
The other benefit that a reflective roof coating provides is thermal emittance. A reflective roof coating of good quality has the tendency to increase the thermal emittance of the roof. This helps to radiate the absorbed heat back into the atmosphere rather than letting it enter your home.
Both of these traits work together and help a home keep cool by reflecting the heat that falls on the roof. This helps reduce energy costs as you need less energy to control indoor temperature.
There are other modifications too that can maximize the energy saving efforts other than reflective roof coating. You can improve the insulation system in your home, starting with installing reflective insulation in the attic and you can also improve the ventilation system of your home. These improvements along with the reflective roof coating can help you save a lot of money.
Reflective Roof Colors
Colors play a vital role when it comes to reflective roof coats. White color is said to be the most effective as it can save up to 50%-90% of energy. However, if you wish to enhance the beauty and can’t compromise on the color, then know that it is going to reduce the effectiveness by 5% to 10%, however, it is still better than having no coating at all.
