India has been experiencing extremely hot summers for the last few years. Several areas experienced heat waves last year and in 2025 as well; there is a heat wave alert for many states in India. This is leading to increasing discomfort and heavy strain on air conditioning devices, which ultimately results in hefty energy bills.
With this continuously rising heat problem, cool roof tiles have become an important consideration for homeowners and builders. If you are planning to buy a new home or renovate your existing one, you should also aim to look for roof heat reduction solutions.
One of the best solutions to naturally reduce roof heat is to install cool roof SRI tiles. These tiles not only help keep the interiors cooler but also help save money on energy bills. Let us dive deeper into the concept of SRI tiles and understand how these tiles can improve your indoor experiences during the summer:
What are SRI (Solar Reflectance Index) Tiles?
SRI tiles or Cool-Roof SRI tiles are a specific type of tiles that are specially designed to reflect maximum sunlight into the atmosphere. These tiles have a high Solar Reflectance Index, which enables them to reflect maximum sunlight and emit most of the sun’s heat. These tiles have a high SRI value, usually above 78. However, for areas with a hot climate, tiles with SRI values over 90 are considered most suitable.
The cool roof tiles from Johnson Endura have an SRI> 90, which makes them suitable for terraces, rooftops, balconies, and even the exterior walls of houses and larger buildings located in hot areas. As most of the areas in India experience extreme heat during the summer season, cool roof tiles have become a must-have for Indian families to fight the heat naturally.
How do Cool Roof Tiles Work?
Cool roof tiles are designed with a special layer of glaze, which reflects maximum sunlight and absorbs minimum heat. As sunlight is the major source of heat, preventing sunlight absorption can help reduce the indoor temperature of a building.
The Endura cool roof tiles can reduce the surface temperature by up to 15 percent. Johnson designs these tiles with a specially formulated glaze coating and then fired at extremely high temperatures, giving tiles the ability to reflect maximum sunlight.
Also, these tiles are given a satin matte finish to ensure slip resistance, making them ideal for terraces, rooftops, balconies, etc. Now that you know the basics of cool roof SRI tiles, let us look at some of their advantages and understand why they are the best roof heat reduction solutions.
Energy Savings: Lower AC usage
As cool roof tiles can help reduce the indoor temperature naturally, the strain on your air conditioning devices is reduced. You can keep the indoors much cooler without putting a lot of strain on your AC 24x7. This further lowers your energy bills and helps save a significant amount of money. Not only this, but the lower usage of AC will also result in reduced greenhouse gas emissions, allowing you to contribute to environmental sustainability. By installing high-quality cool roof tiles, you can reduce your energy bills by up to 50 percent.
Environmental Benefits
Another major reason why you should consider installing cool roof SRI tiles is the environmental advantage offered by these tiles. Cool roof tiles can help reduce the urban heat island effect by reducing the surface temperature of the buildings.
The urban heat island effect refers to a condition where the temperature of cities is higher than that of neighbouring rural areas due to a higher number of heat-absorbing surfaces and higher population. As these tiles reduce the surface temperature, they can effectively lower the urban heat island effect.
Also, as mentioned above, cool roof tiles help lower AC usage, which results in reduced emissions of greenhouse gases.

Installation Tips
When installing cool roof tiles, you need to keep a few important installation tips in mind. Start by wetting the back side of the tile and placing it properly over the mortar. Now, with a 5-6 mm gap, place tiles one after the other, ensuring that the Tile adhesive doesn’t settle on the upper surface of tiles. If it does, keep wiping the tiles simultaneously to avoid stubborn stains.
Grouting can also play a significant role in the effectiveness of these tiles, i.e., how effectively they serve the purpose of keeping the indoors cooler. Ordinary grout might not be suitable as it may crack during the summer, causing leakage problems in the long term. So, it is advisable to use high-quality grouting materials, such as furan grout, polymer sand grout, or epoxy grout.
ROI & Long-Term Benefits
Though cool roof tiles in India can be comparatively costlier, investing in them would be totally worth it in the long term. Here are some long-term benefits of Endura cool roof tiles:
- Highly Durable: Endura cool roof tiles are basically high-quality vitrified tiles with an additional glaze coating for high SRI. These tiles have high mechanical strength, resistance against stains & scratches, and the ability to withstand harsh weather conditions, all of which make them highly durable.
- Easy Cleaning & Maintenance: These cool roof tiles have a smooth surface and extremely low porosity, which makes them stain/scratch-resistant. Hence, these tiles are very easy to clean and rarely need any major maintenance.
- Aesthetic Appeal: You can still achieve your desired aesthetics by installing cool roof tiles as these tiles are available in a variety of colors under Johnon’s Endura collection. However, white-colored cool roof tiles are the most effective.

Installing Endura cool roof tiles can benefit you in many ways while also having a positive impact on the environment. If you still have ordinary tiles installed on your rooftops or terraces, it’s time to replace them with cool roof SRI tiles. It might seem costly to you, but it would be a one-time investment. It will ultimately give you a high ROI as you can save on energy bills.
So, check out Johnson’s Endura cool roof tiles now and choose an option that goes well with your needs and preferences. Remember that white cool roof tiles are the most effective in reflecting sunlight. But to achieve certain aesthetics, you can also consider other light colors available in the Endura cool roof tiles collection.
