Is Cool Roof Coating Sufficient for My House?

People who reside in areas that have long cooling seasons as well as extended hot days, they need to analyze whether the dark-colored stones are supplementing heat to their home’s interior. It should be noted that heat gain can indeed enhance cooling costs, especially during peak demand hours, like late afternoon or when there is electricity breakdown or other such problems.

As per studies conducted in the United States, it has been analyzed that houses in high-heat sections of Texas, California and Florida can reduce their electricity usage by almost 10 to 30% simply by spreading on a heat-reflective coating to their respective roof surfaces. Building professionals call it as cool roof coatings, which is applied to existing rooftops in the form of a liquid paint. With time, the application of cool roof coating has been globally recognized as a feasible way to regulate temperature within a house.

Types of Cool Roof Coating

At present, cool roof paint is available in two primary forms; namely, cementitious coatings and elastomer coatings. The former variant is made using concrete and ceramic particles that are thawed in white acrylic paint. On the other hand, the latter comprise of additional polymers that function to keep the coatings more water-resistant and less brittle.

Almost all variants available in the cool roof coatings market help improve the solar reflectance concerned to your roof’s surfaces, thereby, resulting in lesser electric bills. Furthermore, some of them also contain UV-resistant materials that can potentially escalate your roof’s lifespan.

Is My Roof Suitable for Cool Roof Coating?

It should be remembered that not every roof can prove as a good candidate for applying a cool roof coating.  For instance, people who live in regions experiencing shorter summers and colder winters, the application of cool roof coatings can actually upturn their energy bills. This is because the reflective surfaces still counterbalance heat during winter, while solar heat gain can offer some liberation from increased heating bills.

According to a Stanford research, one need not use cool roof coatings if he/she resides in a densely populated section of the city. Covering your roof with such materials, especially in urban spaces can enhance the heat island index, thereby, proving bad for the environment.
