A cool solution for a hot summer!
Paint the roof bright white, reflect away the scorching sun's might.

This summer consider painting your house roof with bright white paint.
We are in a tropical country and our buildings get heated up on a bright
sunny day. Normal house roofs are gray (cement) in colour and gray is next to
black to absorb heat. Experiments have shown that the main heat source to a
building is the roof and it accounts for around 60% heat input to a typical
building.
A white roof brings down the temperature inside the house by at least
two degrees.
Gray coloured concrete roof acts like a heat magnet and stores lot of
heat. The stored heat slowly gets released into the living areas of a house.
White roofs have more benefits: Thermal cycling of the normal gray
coloured roof from 50 deg C during the day to 10/15 deg C in the night damages
/ cracks the roof and may lead to leaks. Clean white roof has less thermal cycling
and attracts less insects and dust leading to less fungus or algae growth for
clean rainwater harvesting.
