We have a neighbor down the hill whom we like very much, and one day he called to say that the new roof we put on our old barn (at left above) reflects the sun pretty severely into his eyes at certain times of the day. Ugh..... We love the standing seam roof: not only does it match the silos, not only does it remind me of the farmhouses of my youth, not only is it durable, relatively permanent and green (for its heat reflectivity), and not only is it beautiful, it has an authenticity that defies the transient nature of the everyday. It is real.
And to our neighbor's disappointment, we had already ordered the roofing material: it was sitting in the roofer's garage awaiting the trimming of the building, and some decent weather. Finally, the clouds drifted away and the roofers got to it, making quick work of the main roof, holding off of the carport roof until the bookending of that structure is complete.
