One of the best ways to reduce the cost of energy bills in a home is to keep up with a regular roof maintenance schedule. A homeowner can contact a San Antonio roofing contractor for a reflective roof coating, as well. This helps to reflect sunlight away from the surface of the roof, thereby reducing the amount of heat the roof absorbs and resulting in a more comfortable living space for homeowners. Many call this cool roofing, and this coating comes in a number of textures, colors and thicknesses. Cool roofing can make a substantial difference when it comes to a homeowner's energy costs. It also contributes to a better indoor environment and can help to lengthen the lifespan of a roof.

A cool roof works to reduce temperatures within the home in two different ways. In the first place, it serves as a solar reflector, pushing the sun's rays away from the surface of the roof. Secondly, cool roofs work on the principle of thermal emittance. Essentially, the coatings that go on the roof are made of special materials that help to increase the roof's ability to radiate absorbed heat back into the atmosphere. When both of these principles work in tandem, the roof coating is extremely effective at keeping energy costs down, as the home will be much cooler.

Many homeowners wonder how much energy they can save. Before attempting to calculate this, however, a homeowner must understand that these savings are dependent on several factors, including the shape of the home, the coating type, local climate and how energy efficient the home is. For those in a relatively warm climate, homeowners can expect to save up to 70 percent on their energy bills. For those living in a cooler climate, there will be about a 20 percent increase in savings, which is still quite significant.

One of the deciding factors involved in choosing a cool roof coating is the color. While these coatings are available in many types of colors, white coatings are much more effective and can reflect anywhere from 50 to 90 percent of the heat and sunlight to the roof. There are also highly reflective coatings that are made of aluminum that can be painted, which has even higher reflective properties. In this case, the levels are about 60 to 70 percent reflectance. For those who want a colored roof, a cool roof can save homeowners anywhere from 15 to 35 percent on energy bills.
