Re: [Phys-l] paint your roof?

I'm more concerned about the heating portion of this--in our climate MUCH
more energy goes into heating than cooling and if anything your 'subjective
data' might support black for heating purposes.  (I spend about $100
annually running the central air but can run a $200 natural gas bill during
December and January.)  If white is only a small benefit--or of no
benefit--for the heating season, it won't sell in my neck of the woods!
