Can You Put Color in Roof Coating Products?

Liquid Roofing

• Metal roofs and other types of roofing materials can benefit from the use of a special kind of roof coating that is akin to liquid rubber. These coatings are often used on metal roofs for the purpose of sealing the roof and preventing future leaks. They can also provide an effective barrier that protects the roofing material from hail and other falling debris. Many of these coatings are white, but you can change the color by adding about three ounces nonoil-based universal colorant.

White Roofs

• While you may not necessarily want your home to have a white roof, this is one option that may help you save on energy costs. Although you can add color to roof sealants for a more decorative appeal, a protective white roof coating will provide the most reflective protection against ultraviolet radiation and heat from the sun. These roof coatings have been shown to reduce energy costs significantly. For instance, Washington State University cites research from the Cool Roof Rating Council in 1998 that showed savings ranging from 35 to 67 percent.

Asphalt

• Many roofs are covered with an asphalt covering that often absorbs heat and retains it. The result is that the home's attic retains the heat and forces the rest of the home's cooling system to compensate for this heat transfer. It is possible, however, to purchase asphalt roof coverings that have an embedded material within them that reflects the sun's rays.

Colors

• Although white roof coatings are more common and the simplest to apply, liquid roof coatings can be purchased or mixed to form a variety of pastel colors that may be more suitable to your home's exterior. Dow Construction Chemicals notes that pastels may usually be used and often provide an acceptable alternative to white in that they still meet local, state and national energy regulations. Dow recommends using a dry pigment additive as opposed to liquid additives. Liquid additives often contain surfactants that prevent the protective coating from functioning as intended.
