Austin Roofing: Article About Reduce Energy With Reflective Roof Coating
There are many challenges homeowners face with Austin roofing. The dry, warm climate requires advanced home alterations to not only prolong the life of specific home elements but also to enhance its efficiency. Although remodeling home interior spaces for efficiency is a common practice, the most notable changes occur on the outside of the structure: Specifically, the roof.
If a roof is not designed to thwart the absorption of Texas heat, cooling systems must work overtime to keep occupants comfortable. This not only results in greater utility bills but also strains local infrastructure and resources. The most effective way to keep a home cool while baking under the constant presence of intense sunlight is through a reflective roof coating.
In the most fundamental sense, reflective roof coatings is the application of specialized materials designed to deflect UV rays from being absorbed while simultaneously enhancing the thermal emittance of the home. As sunlight bears down on traditional roofing materials, its heat is literally absorbed into the home. The constant presence of sunlight translates into a substantial rise in internal home temperatures, and the result is an increase in ambient home temperatures, which can lead to excessive air conditioner use.
However, when a reflective roof coating is applied, the sun's UV rays are reflected before it has time to be absorbed.

Along with this potent high solar reflectance, the thermal emittance actually gathers internal heat absorption and directs it out into the atmosphere. Through the combination of these two methods, interior spaces remain at a consistently cool temperature.
These two qualities translate into real world energy savings. Although there are several factors that determine the true cost savings, such as the home's shape and the exact type of reflective coating used, the majority of homes experience anywhere from 20 to 70 percent energy savings.
When selecting a reflective roof coating, it's imperative to review its reflective rating. As a general rule of thumb, white reflective coatings are the most powerful as they deflect anywhere from 50 to 90 percent of sunlight. However, they are also some of the more expensive options. A decent mid range coating is made out of a specialized aluminum material, which reflects anywhere from 60 to 70 percent of sunlight. Because the shopping process for a reflective roof coating can become confusing, especially when dealing with unique roof shapes, consult with a professional roofing contractor for advice on the ideal coating type based upon reflective level and cost.
