How to Prevent Heating of Roof in Summer Days?

Here are the methods following which you should be able to prevent your roof from heating during summer days. 

Using Heat Reflective Insulation

During my research, I learned that heat-reflective insulation materials can be used as they are specifically designed to reflect heat. You can use these materials under the roofing panels.

Cool Roof Coating

If you have a metal roof, then you can apply reflective, cool roof coatings over it. This will help in reflecting the sunlight and release the absorbed heat rather quickly. 

Another method that I have learned from my personal experience is keeping the roof clean. Sometimes, debris on the roof can trap heat as it makes the roof less reflective. I hope this resolves your query about how to keep rooftop room cool in summer.

How to Cool Roof in Summer?

1. The first thing you can do to cool your roof during summer is to increase the shade level. If you block the path of direct sun reaching your roof, the place will feel cool to a great extent. Do so by planting tall trees around your home. 

2. Another idea is to use solar shingles and tiles. These are new products which help in decreasing the temperature of the roof. They do so by reflecting the solar and infrared radiation.

3. As I did, you can paint your house roof in light colours. Dark colours absorb heat and thus lead to an increase in temperature. If you use lighter colours, the heat absorption will reduce. 

This is how to protect roof from sun heat in India. I hope this helps.
