There is a link somewhere on builditsolar.com for someone that did it. Don’t see any reason why it wouldn’t bind as there is a granular base. Roofs are whitewashed regularly in large parts of the world. Will need to be renewed periodically but should extend the life of the roof dramatically.

Subject: [Greenbuilding] Whitewash for roofs?
I was in a meeting the other day and someone asked me about the utility of white-washing roofs with traditional whitewash solutions. Here’s basic info from wikipedia on the subject. http://en.wikipedia.org/wiki/Whitewash . The goal of course is to achieve the energy savings available from white roofs at a lower cost than conventional paints, even though it would have to be reapplied every few years. I was wondering if anyone had had any actual experience with this. I’m wondering how whitewash would adhere to asphalt shingles. If this would work, it could be a boon to low income communities everywhere.
