They are like very thick paints that can protect the roof surface from ultra-violet (UV) light and chemical damage, and some offer water protection and restorative features. Cool roof coatings deliver higher solar reflectance and higher thermal emittance than standard designed roofing coats. Standard or dark roofs can reach temperatures of 150°F or more in the summer sun. A roof with a cool coating under the same conditions could stay more than 50°F cooler and save energy and money. Highly reflective and anti-fungal by nature, the coating is easy to clean and offers excellent value for money. It is easy to apply via brush or rollers and offers excellent water resistance and superior crack bridging.  Advantages of cool roof coating Minimum surface preparation needed Available as ready to use High solar reflectance index (SRI) indicates high degree of cooling effect Crack-bridging High resistance to chloride penetration Algae and fungi resistant Highly flexible and Vapour permeable Simple and fast application Excellent adhesion to concrete, Ultra violet rays and weather resistant Reduces the surface temperature of roofs by 50% compared with a dark coloured covering Reduced energy cost Eco friendly Cool roof coating products Acrylic based cool coats – These contain cross-linking polymers, special glass microfibers, pigments and advanced antifungal additives that provide long lasting tough waterproofing membrane. The high Solar Reflective Index of the membrane serves as a heat reflective surface and reduces heat ingress keeping the interior of the building cooler. Fiber filled liquid cool coats – These are a ready-to-use waterproofing, white product, with high solar reflectance and thermal index (SRI) of 105, for external applications made from synthetic resins in water dispersion, and when dry forms a continuous, flexible waterproofing membrane. Polymer cool coats – These are water-based white coloured emulsion consisting of polymers and specially designed hollow “microspheres”, less than 100 microns in diameter with non conductive properties. These microspheres collectively act as thermal insulation blankets covering the structure effectively reflecting solar radiation back into the atmosphere. PUD hybrid cool coats – These are water based, high solids, PUD hybrid coats that contains both reflection and nano insulation pigments for best in class heat protection. These are powered with micro-fibres for excellent waterproofing & crack resistance. Single-ply cool coats – These are prefabricated sheets rolled onto the roof and attached with mechanical fasteners, adhered with chemical adhesives Modified bitumen cool coats – They have one or more layers of plastic or rubber material with reinforcing fabrics, and are surfaced with mineral granules or a smooth finish. Spray polyurethane cool coats – These are formed by mixing two liquid chemicals together that react and expand to form one solid piece that adheres to the roof. Foams are highly susceptible to mechanical, moisture, and UV damage, and rely on a protective coating.
