Before applying elastomeric roof coating, it’s important to make sure the roof is clean and debris-free. Power washing is an effective way to remove debris. The roof should also be completely dry before coating. Most elastomeric roof coatings cure within one to four hours depending on the weather conditions. If you’re applying the coating during a particularly humid day, the coating may take up to 48 hours to cure. However, most elastomeric roof coatings are completely dry to the touch within eight to twenty-four hours.


An ENERGY STAR elastomeric roof coating is a durable, elastomeric material designed to reduce energy costs by up to 25%. This product features colour-infused nano ceramics, which selectively reflect heat. They are available in pails of one gallon and five gallons. They can be applied in two coats and dry in two to three hours. The product is suitable for most types of roofs, although it is not recommended for flat or shingled surfaces. It is also not recommended for roofs with a dead level surface. Energy Star Kote is designed for exterior application only and should not be stored in a climate below 50 degrees Fahrenheit.

When looking for an ENERGY STAR elastomeric roof coating, check the corresponding label on the product. This label is a seal of approval from the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE). If you’re looking for an elastomeric roof coating that meets strict requirements, choose a product that is ENERGY STAR qualified.

LEED Green Building Rating System

The LEED Green Building Rating System is a voluntary, consensus-based standard for energy and environmental design in buildings. In addition to green buildings, LEED projects achieve gold or silver certification. A cool roof can earn LEED points under the category of Sustainable Sites. It can reduce urban heat islands, which can be up to 22 degrees warmer than air in neighboring less-developed regions. To be certified, a roof must meet a specific minimum SRI (Solar Reflectance Index), or SRI-78 for low-sloped roofs and 29 for steep-sloped roofs.

The elastomeric roof coatings from RCUSA are a proven solution for energy-efficient buildings. Using them in buildings reduces roof temperatures, reducing the need for air conditioning and lowering carbon emissions. Additionally, these roof coatings reduce energy costs for buildings and can meet the LEED green building rating system standards. To learn more about these benefits, contact RCUSA today.


While there are many benefits of elastomeric roof coatings, there are a few things to keep in mind when choosing the best coating for your property. Essentially, elastomeric coatings have elastic properties and don’t crack easily. Different elastomeric roof coatings are better suited to different kinds of applications. For example, some coatings offer 600 percent stretch and better resistance to weather changes. They also offer better insulation and good adhesion when painted over. Ultimately, elastomeric roof coatings offer long-term performance and a low life-cycle cost.

The benefits of elastomeric roof coatings include the fact that they are durable and will not easily crack, even with extreme weather changes. They also seal existing leaks and prevent further damage from occurring. Many elastomeric roof coatings are SPF (Super Polymer Foam), which means they are made of silicones, acrylics, and urethane. Each of these products must meet a set of criteria, such as abrasion resistance, hardness, and tear strength, before being approved for use on roofing.


The Reflectivity of Elastomeric Roof Coatings may reduce the energy used to cool manufactured homes by up to 25%. The results from two studies conducted by the Mississippi Power Company showed that reflective roof coatings significantly reduced cooling energy use. They monitored two identical single-story commercial office buildings. The building with the reflective white coating had a 22% reduction in summertime air conditioning consumption. In other words, a reflective roof coating is an excellent way to reduce cooling energy use.

Reflectivity is an important measurement of the ability of a roof coating to reflect light. It is represented as a percentage between 0 and 100 percent, and a reflectivity of 85% or more is considered to be excellent. For example, a white roof coating system can reflect upwards of 80% of the sun’s energy, reducing the likelihood of excessive heat gain in the roof structure. Another important parameter to look for is the solids by volume, or the amount of solid material that remains after the substance dries. This measurement is important for ensuring the proper dry film thickness, but has no bearing on the performance of the coating.


When comparing elastomeric roof coatings, look for their degree of elasticity. Different types exhibit different elasticities and will respond to various conditions better than others. To find the best elastomeric coating, look for a national standard that provides a set of testing procedures for elastomeric roof coatings. For a more comprehensive evaluation of elastomeric roof coatings, contact a manufacturer representative like RoofSource.

Before applying elastomeric roof coating, make sure that the surface is free from debris and moisture. If you cannot avoid the presence of debris, power-washing the roof is a good idea. In addition, make sure that the surface is dry to prevent any traces of moisture. Elastomeric roof coatings cure within one to four hours, although this can take a bit longer if the weather is humid. Otherwise, they will be completely dry to the touch in eight to 24 hours.
