Indian summers can be extremely harsh, with the sun's rays beating down relentlessly. On a typical sunny day, your roof can become significantly hotter than the surrounding air, sometimes by as much as 50 degrees. This intense heat can raise the temperature of your entire house.
No matter how much air conditioning you use, if your roof is scorching, your home won't cool down efficiently. This leads to wasted energy and higher electric bills. So, what can you do to keep your roof cool during the summer? Here are some effective strategies:
Paint Your Roof a Lighter Color
Basic color theory tells us that dark colors absorb heat, while light colors reflect it. A dark concrete roof absorbs more heat from the sun, which then warms your entire house. Switching to a lighter-colored roof will reduce the amount of heat absorbed. You can either paint the entire roof or replace dark shingles and tiles with lighter ones.
Increase Shade on Your Roof
Adding shade to your roof can significantly reduce its temperature. Planting tall trees and vegetation around your house can provide natural shade. Additionally, you can install green fiber or net shades on your roof to block the direct sunlight.

Start a Rooftop Garden
If you have a flat, accessible roof, consider creating a rooftop garden. Using planters and pots or building flowerbeds can add a protective layer between your roof and the sun. The evaporation and transpiration from the plants will also cool the air around your roof.
Consider Solar Reflective Shingles and Tiles
Solar reflective shingles and tiles are modern solutions designed to reflect solar and infrared radiation. These products can help cool down your roof and reduce energy costs.

Install Solar Panels
Solar panels not only help keep your house cool but also make it more energy-efficient. By installing solar panels on your roof, you create a barrier between the roof and direct sunlight, lowering the temperature of both the roof and your home. The panels capture solar energy to provide renewable electricity, reducing your reliance on air conditioning and cutting down on electric bills.
Set Up a Roof Misting System
A roof misting system can help cool your roof by spraying water over its surface. This can be done with a simple garden hose set to mist or by installing a professional evaporative cooling system. As the water evaporates under the sun, it cools the roof, potentially reducing temperatures by 40 to 60 degrees.

Ans 1. Cool roofs reflect more sunlight and absorb less heat than standard roofs, making them over 50 degrees F cooler, contributing to energy savings and comfort in hot weather. Options for creating a cool roof include materials like modified bitumen, single-ply membranes, cool roof coatings and even green (vegetated) roofs.
Ans 2. A cool roof is designed to reflect more sunlight than a conventional roof, absorbing less solar energy. This lowers the temperature of the building just as wearing light-colored clothing keeps you cool on a sunny day. Conventional roofs can reach temperatures of 150°F or more on a sunny summer afternoon, sun.
Ans 3. Roof mist cooling system reduces the roof surface temperature by spraying an extremely small amount of water across the roof. Spraying allows to cool the roof as the water evaporating from the surface captures the heat.
Ans 4. Thermocol Insulation for Heat & Cold Thermal insulation can be defined as the process which aids in the reduction of the transfer of heat from outside to inside. Thermocol insulation enables consistency in room temperature by keeping the room cooler in summer and warmer in winter from the outside.
Ans 5. Insulating materials are bad conductors and so this reduces the heat loss by conduction. The material also prevents air circulating inside the cavity, therefore reducing heat loss by convection. Heat loss through the roof can be reduced by laying loft insulation.
