Yes, I’d read of idea to paint roofs white. From the Guardian:
Should we paint the world white to tackle the impact of global warming? Hashem Akbari, a scientist at Lawrence Berkeley National Lab in California thinks so, and is launching a worldwide campaign to brighten up our cities. Turn enough rooftops and roads a whiter shade of pale, he says, and enough extra sunlight will be bounced back into space to cool the planet.

Paint for victory: new weapon in climate war is brilliant white roofs
Painting your roof white could help slow climate change by reflecting sunlight back into space. So would painting the moon. Wild eco-goose chase or radical thinking?
