Time to repaint the roof white as #Bhubaneswar becomes the hottest city in the country. Here just a single coat of white cement paint has been applied and the results were immediately felt as I didn't have to use air conditioner for most part of the day. We have doing this every year for the past 15 years.
White roof reflects back light and heat back to the atmosphere, thereby keeping the interiors as well as the city cooler. Yes, it helps in reducing #globalwarming too.
A good 10 degrees Celsius reduction can be attained by this simple and affordable solution. You can save around 20% on electricity costs.
A 1500 sqft rooftop would cost around 1000-1500rs using white cement paint. Cheaper if lime is used. In my experience, lime doesn't hold well during rains. Cement paint with DDL adhesive lasts a year. If you don't want to repaint every year, you can use the expensive elastomeric paints that will last 5 years easily but cost you 10rs per sqft. Elastomeric paints will waterproof and protect your roof better.
