Light-colored materials are less reflective than dark materials. This is why it’s more comfortable to wear light-colored clothing on a hot summer day than dark clothing. The same principle applies to roofing systems. In this article, Earl W. Johnston Roofing, LLC talks about the workings of a cool roof, and how your roofing contractor can apply this innovation to your existing roofing system.
Cool roofs are designed to reflect visible, infrared and ultraviolet rays better than standard roofs, and are thus more efficient in reducing heat absorption. Cool roofs also have high emittance levels, meaning they are highly capable of releasing what little heat they have absorbed.
Cool roof technology can be applied through various means, such as highly reflective coating, tiles, shingles or sheet covering. Due to recent scientific developments, cool roofs are no longer limited to light-colored materials. You may consult your roofing company for their cool roof options and color selections.
Among the various cool roof techniques, the reflective coating application is the most popular. This particular coating is made of pigmented polymeric binders. The pigment is usually a mixture of silver flakes, asphalt and pure aluminum. Reflective coating can take on the form of very thick paint. It can be applied to almost all types of roof including metal and built-up roofs. Primer may be needed before the application, but the most important preparation is a thorough cleaning of the roof surface.
Residential properties in warm climates can greatly benefit from cool roofs. A cool roof keeps your home cooler naturally, which reduces the burden on your air conditioner, thus generating energy savings. With the help of your local roofers, reflective coatings can also increase the service life of your roofing system. As an added bonus, your cool roof benefits the environment by reducing the air temperature in your area through the urban heat island effect.
