Painting a roof white?

I read once a long time ago, that if very single rooftop in the world was painted white, it would go far towards stemming the warming we currently are starting to experience.

Yes. Yes it will.

Also look at at Plascon Nuroof cool. It contains a UV reflective component which apparently reduces heat by an impressive amount, plus, you get to use a colour other than white :-)

I've painted the roof of my house with this prior to installing the panels about a year ago. I've used the greyish colour - temperature of the roof sheets and inside the roof is much lower than before it was painted.

Some of the more paraat farmers in the Karoo paint their roofs silver to cool the house down. I don't like the glare. This is something I definitely will try. Our loft is like Chinese torture in summer. Despite the high ceilings we still experience temperatures over 30 degrees Centigrade indoors.
