Black roof? We paint our roofs WHITE here to keep the heat down. I imagine a black roof may have the opposite effect :p

Well, if there was a paint that we could flip a switch to go from black in Winter to white in Summer, then ya, that might work great! Otherwise we'll be in trouble for 1/2 the year. :)

Just paint it 2x a year. That way, it never needs painting cuz the paint job will always be fresh. :hide

Simple, passive heat with PC fan option. Works in winter with snow on the ground too.
