Cool Roof Paint is a specially designed, sunlight-reflective paint that reduces roof temperatures by reflecting rather than absorbing solar heat. Applied on RCC Terraces, Concrete Slabs, Metal Sheds, GI Sheets, Asbestos Roofs and Poly-Flex, Cool Roof Paint is amongst the most efficient and economical methods for reducing indoor heat. It saves electricity bills and extends the roof’s lifespan. The brand COOLROOF® has earned the reputation of being India’s premier heat-reflective paint. This brand is tested and certified as per ASTM / LEED specifications with an industry-high Solar Reflective Index (SRI) value of 122.

What is Cool Roof Paint?
Cool roof paint, also called heat reflective paint, sun reflective paint, or high albedo paint, is a water-based acrylic and nanotechnology coating formulated with high solar reflectance and thermal emittance. Unlike ordinary roof paints that absorb the sun’s infrared radiation and heat up the building underneath, cool roof paint bounces most of that solar energy back into the atmosphere. This keeps the roof surface — and everything below it — significantly cooler through the day.
COOLROOF® Paint achieves a Solar Reflectance of 95% and Thermal Emittance of 91%, giving it an SRI value of 122 — well above the minimum threshold of 78 required to qualify as a genuine high SRI paint for green building certification.
How Does Our Cool Roof Paint Work?
The roof coating technology is based on solar reflectance index (SRI). The sun emits visible light, infrared and ultraviolet rays. When dark roofs get exposed to these rays, the rays are trapped inside and converted into heat energy, which then radiates inside the building and makes the air conditioning system work extra hard. Cool roof coatings that have high SRI contain reflective particles and nanotechnology materials that can:
- Reflect up to 95 % of the solar radiation
- Emit the heat quickly due to a high emittance rate
- Generate a heat insulating barrier
- Lower the roof temperature up to 20° C
Key Advantages of Our Cool Roof Paint
1. Cooler Interior
Cool roof paint will prevent the sun’s rays from affecting your ceiling or the upper floor of the building by keeping the interior much cooler.
2. Reduced Energy Consumption
The reduced absorption of heat will put less stress on air-conditioning systems, which can reduce electricity usage for cooling purposes and save up to 30% in cooling expenses.
3. Extended Roof Life
Thermal fluctuations caused by the process of contraction and expansion result in cracks. Cool roof coating reduces thermal strain to help you protect the waterproofing layer and other materials of the roof.
4. Water-resistant, UV & Mould Resistant
Apart from being reflective and providing cool roof painting services, this product protects against the harmful effects of the sun’s rays, algae and fungi during any season of the year.
5. Green Building Projects
One of the few coatings in India certified by GRIHA and IGBC organisations, COOLROOF® will help in getting the credits required for green buildings.
Where Can Cool Roof Paint Be Applied?
One of the biggest advantages of cool roof paint is its versatility across almost every roofing material used in India:
- RCC and concrete terraces — see our dedicated guide on RCC roof paint and concrete roof paint
- Metal and GI sheet roofs — see our dedicated guide on heat reflective paint for metal & GI roofs
- Galvalume sheets and pre-coated roof sheets
- Asbestos cement roofing sheets
- Poly-flex and fibre roofing sheets
- Residential terraces, villas and apartment roofs

Cool Roof Paint vs Traditional Roof Paint
Ordinary weatherproof or enamel roof paints are designed mainly for aesthetics and basic water resistance — they do very little to stop heat transfer. Cool roof paint is formulated specifically for solar reflectance and thermal insulation, using reflective pigments and nano-technology additives that ordinary paints lack. The result is a measurable drop in roof surface temperature, lower indoor heat, and real electricity savings — benefits a standard roof paint simply cannot deliver.
Industries That Benefit from Cool Roof Paint
COOLROOF® has been trusted by organisations such as Indian Oil, Indian Army, RBI, Google India, Godrej and Blinkit for large-scale roof cooling projects.
How to Apply Cool Roof Paint
- Surface cleaning — remove dust, algae, loose paint and grease from the roof
- Crack filling and minor repair of the roof surface where required
- Priming (if the roof surface demands it, especially metal and GI sheets)
- Application of 2–3 coats of cool roof paint using brush, roller or spray
- Curing period before the roof is exposed to heavy rain or foot traffic
For best, warrantied results, COOLROOF® offers full turnkey application services — including site inspection, material supply and professional installation.
Cost & Packing Sizes of Cool Roof Paint
COOLROOF® cool roof paint is available in 10 kg, 20 kg and 50 kg packs, with custom packing available for large industrial and B2B orders. Pricing depends on roof area, surface type and number of coats required. Contact our team for a free site assessment and quotation.

Signs Your Roof Needs Cool Roof Paint
Wondering whether your building requires cool roof paint? Here are a few clear indicators of having too much solar heat accumulation. Rooms on the top floor are much warmer than those located at lower levels, and air conditioners cannot function properly due to constant work but still cannot cool down the space. The roof gets too hot to touch by noon, and bills for the cooling system increase dramatically during every summer period. In addition, it is essential for people working or employed in a shed or a warehouse to experience discomfort.
Maintenance Tips for Cool Roof Paint
Cool roof paint is meant to be a maintenance-free product; however, following some basic practices will help you keep your reflective roof paint intact for years to come:
- Regular cleaning of the roof surface to eliminate the deposition of dust, dirt, and other pollutants that cause a reduction in reflectivity.
- Post-monsoon inspections of the roof to ensure there are no cracks, blisters, or peeling.
- Do not drag heavy and sharp objects over the painted surface.
- Cut off the overhanging branches to avoid accumulation of leaves and algae formation.
- Recoat the roof after every few years for high-traffic or exposed industrial roofs.
Cool Roof Paint and Energy Efficiency Ratings
With rising emphasis on passive cooling systems through the implementation of energy code and green building standards in India, cool roof paint technology is gaining acceptance as an effective method to increase the energy efficiency rating of a building. Since this method consumes no energy, does not have any moving parts, and has no operating costs, a highly reflective paint such as COOLROOF® provides one of the best ROI’s among all energy-saving products.
What Our Clients Say
Frequently Asked Questions About Cool Roof Paint
Cool roof paint is a reflective coating applied on roofs to reflect solar heat and reduce roof surface temperature, keeping buildings cooler and reducing cooling costs.
COOLROOF® cool roof paint can reduce roof surface temperature by up to 20°C compared to an untreated roof, depending on the roof material and local climate.
Yes. Cool roof paint is compatible with RCC, concrete, metal, GI sheets, galvalume sheets, asbestos sheets, pre-coated sheets and poly-flex roofing.
Yes. By reducing heat entering the building, cool roof paint lowers the load on air-conditioning systems, cutting cooling energy costs by up to 30%.
A genuine high SRI cool roof paint should have an SRI value above 78. COOLROOF® has an SRI value of 122, with 95% solar reflectance and 91% thermal emittance.
A quality cool roof coating like COOLROOF® is waterproof, UV-resistant and fungus-resistant, engineered for long-term durability with minimal maintenance.
No, but many cool roof paints, including COOLROOF®, also provide waterproofing along with heat reflection, offering dual protection for the roof.
Most roofs need 2 to 3 coats of cool roof paint to achieve full, uniform opacity and maximum solar reflectance.
Cool roof paint delivers its biggest benefit in hot, sun-intense climates, but it also protects roofs from UV damage and water ingress year-round in any climate.
