White color reflects heat and light. I have painted the roof of my parental house where I live, with white colored cement paint / white exterior base paint, for the past 5 years. This has reduced the internal heat drastically. However, the paint washes off within a couple of years. I have painted my roof white thrice in the last five years. See photo below.
Now, I want to make the roof of my house under construction permanently white. Is there any way to do this during roof plastering work ? It is urgent as the roof plastering work will be taken up in a couple of days.
