According to IPCC, the Earth’s temperature will rise by 2 to 7 degrees Celsius past 100 years. Similarly, the temperature difference between the urban environment and the surrounding rural areas will be 5 to 9 degrees Celsius. Additionally, 80% of the world’s population will reside in urban areas in the next 50 years. Protect your home with roof cool treatment. Stay cool, save energy, and extend your roof’s lifespan. To mitigate the problematic changes, entrepreneurs and businesses will need to develop new, innovative solutions.
Roofs cover around 20-25% of the urban surfaces and absorb 80% sunlight that falls on them. This energy is converted to heat, resulting in pollution, rising temperature, and higher costs. Cool roofs together with insulation help to minimize the effects. This solution is cost-effective and adaptable to slight changes in external temperature.
Roof Cool Treatment Services brings about comfort, relaxation, and safety for everyone. You can select from a variety of roofing applications, such as asphalt shingles, green roofs, reflective paint, single-ply membranes, and others. Or, if you are unaware of the material specifics, contact experts from Sky Chemical Services today!

Solar Reflectance
As per standards, a cool roof is reflective and emissive; it reduces the amount of heat ingress and maximizes the amount of heat repulsion. Solar reflectance or albedo, is the fraction of sunlight reflected in the atmosphere: White surfaces or reflective colored materials can reduce the temperature of cities and buildings significantly.
Solar reflectance ranges from 4% to 90% for snow-covered roofs. As for cool roofs, the value should be 0.65 or above.
Solar Reflective Values of Common Colored Surfaces
| Colors | Solar Reflectance Value |
| Charcoal Grey | 0.29 |
| Deep Red | 0.41 |
| Matte Black | 0.26 |
| Teal Green | 0.26 |
| Zinc Grey | 0.39 |
| Antique Copper Cote | 0.33 |
Thermal Emittance
Thermal emittance helps a surface cool by radiating heat away from the rooftop. Nonmetallic and metal surfaces offer the highest thermal emittance. This property is measured on a scale from 0-1. Different materials exhibit different thermal emittance values, influenced by factors, such as texture, surface finish, and chemical composition.
Thermal Emittance Values of Common Colored Surfaces
| Colors | Solar Reflectance Value |
| Pure White | 0.85 |
| Metallic Silver | 0.67 |
| Light Green | 0.87 |
| Olive Yellow | 0.84 |
| Grey Beige | 0.86 |
| Cream | 0.86 |
Did You Know?
- Increasing the roof reflectance from 0.1 to 0.6 can reduce energy costs (annual) by 10 to 20 percent. This helps to reduce the need for air conditioning.
- Reconstructing 2-3 billion sq. meters of commercial building roof in the US can yield annual savings of $700-750 million with a reduction of 6.2 million tons of carbon dioxide.
- Cool roofs are low-cost investments. The average annual energy cost saving for a white roof is approx. $0.20 per sq. meter. (liquid-applied membranes).
- Reflective surfaces tend to remain cooler than less-reflective ones.
- Solar reflective materials help reduce emissions of nitrogen oxides (NOx), carbon dioxide (CO2), sulfur dioxide (SO2), or mercury (Hg) in industrial sectors.
