Generally, weathering tiles would be placed on top of the roof surfaces to reduce heat evolving inside the building.

However provision of weathering tiles is not sufficient to reduce the heat inside. So now we are depending on other electronic households such as Air conditioner, Air cooler to cool the temperature inside the building. 

It eventually affects energy consumption and atmosphere.

What is White Roof Paint Coating?

White roof paint is a type of paint that is applied to the roof surface to reflect the sun rays and reduces the heat infiltration inside the building.

White Coated Roof absorbing sun light heat

White Roof Paints contain high heat-reflective pigments that make the sun rays to reflect and penetrate little inside the building. This action allows the building to remain cool and reduces the energy consumption by electronic cooling items such as AC, Cooler.

Basically, the more light an object absorbs the more heat it produces. The black colour absorbs the sun rays but white colour partially reflects the sun rays and partially absorbs it. 

Benefits of White Roof Paint

  • Cost-effectiveness
  • It reduces the heat emission inside the building up to 92%. 
  • It is more durable than weathering tiles and can be coated every 5-6 years.
  • It reduces energy consumption. Less heat equals less Air Conditioning time.

How much does it cost?

White roof paints long last for at least 5-6 years after that the performance gets deteriorated because of sedimentation of dust and atmospheric pollution.

It depends on the brand. Tentatively it costs around INR. 12.50 – 20.00 per sq.ft

There are different types of paint available in the market so we have to choose and procure good branded white roof paint to get the full benefits.
