The roofs of houses become hot during summer, and the heat from a roof can make a room significantly hot. A roof becomes hot due to the sun rays falling on it as it absorbs the heat and dissipates it after the sunset. The roof and walls get heated during the day, and they radiate heat inside the rooms due to which they become warm in summer.
Cooling the roof can do much to cool down the rooms and reduce the temperature of your interiors. Therefore, it is essential to cool your roof to keep the entire home cool from inside. Let us check these DIY tips to cool down your roof in summer.
Grow plants on the terrace
Plants can keep a roof cool significantly as the soil is an insulator. The moist soil can keep the roof your house cool in summer. You can use flat containers and fill them with the right mix of soil and natural organic manure.
Then you can cultivate some tropical plants that can survive in harsh summer as they need to tolerate the direct rays from the sun. Although you can use many ways to put a shade on the plants, still it is hot on the roof in summer. You need to water the plants daily to fulfill their watering requirements and keep the soil moist. The moist soil acts as an insulator and prevents the heat of the sun to be absorbed by the roof.
Coat the roof with white lime
Applying a layer of white limewash on the roof of your house can create a reflective surface on the terrace. The reflective surface reflects most of the sun rays and keeps the roof cool in summer. Only a little heat enters the roof, and it does not get heated as much as without the limewash layer. Although the coat of limewash may wash away with rains, homeowners need to recoat with a fresh coat every summer. You may also consult roofing experts for a professional coating job.

The elastomeric paint is made up of a polymer that expands and contracts with the material on which you apply the paint. Homeowners can use two coats of bright elastomeric paint on their flat roof to improve its solar reflectivity. Tests on elastomeric paint show that it can improve the reflection of sunlight and heat from 60 to 75 percent. Coating your terrace with elastomeric paint keeps your roof cool and reduce the energy consumption to cool your home.
Solar Photovoltaic Roofing Panels
Adding an ultra-thin solar photovoltaic panel can also help you to cool your roof. These panels cover the surface of your roof and prevent the falling of sunlight on the same. They reduce the surface of the terrace that receives the sun, thereby reducing the heating of the roof. Moreover, they produce electricity to power your house and offer a backup when the power is gone.
Homeowners can also apply PVC sheathing to their roof. These sheets have seams that keep the water away and protect the roof from wind damage due to its smooth texture. The manufacturers of PVC sheathing can also help homeowners upgrade their roofs.

A windcatcher is an onion-shaped dome with vertical vanes that helps to catch and turn in the winds flowing over a building.
Homeowners can install windcatchers on their terrace to turn in the cool air in the morning and evening to cool down their house. Moreover, they can turn off the windcatchers in the daytime when the sun is at its peak.
