In my neighborhood, finished in 2000, houses with identical floorplans were required to have external differences that would keep them from looking cookie-cutter. One of those differences was in the rooflines. My own roof is narrowed at the top, reducing the amount of space available for panels. A neighbor just installed roof panels a month ago, the first I've seen in this Minnesota city. Their roof is much more rectangular than mine.
