Painting the Roof?

An uninvited handy-man stopped by our house this afternoon. He asked if we wanted to have our roof painted.

Daniel, who had not even considered painting the roof, thanked him for the offer, but turned it down.

I must say I have also never considered that we would paint the roof. The walls and window frames, yes, but not the roof. Perhaps it would be a good thing to do, but I have no clue that it would be. I guess we can just let it be.
