Folks, I am about to put a new roof on my house, a type of coated metal called MasterRib: http://www.unioncorrugating.com/300_500_chart.html I can't decide on color and seek your advice. I have it narrowed down to the "Terracotta Red" and the "Unpainted Galvalume (aka. "mill finish"). If it were purely aesthetics, I think I'd go red. My house is wood siding (with a clear finish) and my trim is blue. I saw a house with the red roof and blue trim and it looked pretty nice, so I'm not worried about the colors clashing or being locked in to a certain trim color (this roof should supposedly last the rest of my life, easily). But the unpainted is over twice as reflective (68% total solar reflectance versus 32%). However, both qualify for the energy tax credit, and my house is pretty well-shaded in the summertime, so I don't know if it's that big a deal. And possibly the unpainted would look nicer; it can be pretty gloomy in the woods here in summer, and the bright "tin" look seems like it brightens things up a bit in some other houses I've seen. Also, the job will be about $500 (5% of total) less with unpainted. Thoughts ?
