People who live in tropical climates usually wear light-colored or white clothing to help keep themselves cool. They know that light colors reflect heat and sunlight; whereas dark colors absorb heat and light. Buildings are similar to people. If you have a dark-colored roof, your building will be hotter than if it had a light-colored roof.
Cool Roofs are roofs consisting of materials that very effectively reflect the sun’s energy from the roof surface. Cool materials for low-slope roofs are mainly bright white in color, although non-white colors are starting to become available for sloped roof applications. Cool Roofs must also have high emissivity, allowing them to emit infrared energy. Unfortunately bare metals and metallic coatings tend to have low emissivity and are not considered cool materials.
Cool roofs reduce the roof surface temperature by up to 100 degrees Fahrenheit, thereby reducing the heat transferred into the building below. This helps to reduce energy costs (by keeping attics and ducts cooler), improve occupant comfort, cut maintenance costs and air conditioning replacement costs, increase the life cycle of the roof, and reduce urban heat islands along with associated smog
Cool Top Roof Paint
Cool Top is a bright white coating for Metal Roofs, Smooth Asphalt, Shingle Roofs or Granulated Asphalt roofs. It dramatically lowers roof surface temperatures resulting in lower AC costs while it prevents the normal high temperatures that bake out essential oils or cause extreme contraction and expansion, which results in premature roof failure. Prolong your asphalt roof lifespan by blocking UV and cutting heat with Cool Top reflective white roof coating. Prolong your metal roof life by eliminating excessive movement and thermal shock.
CeramaX Roof Elastomeric Coating
CeramaXTM is a reflective, insulating ceramic fortified waterproof roof coating for professional application. It cuts heat absorption and dramatically lowers air conditioning bills while preventing water intrusion. Two decades of Space Shuttle technology developed by NASA makes this product the ultimate coating for protecting, waterproofing and reducing heat load. AC savings can often pay for the application of CeramaX in only a short time
