The cheap metal roof types look bad the long sheets with high fastening ridges. But you can get metal rooves that look indistinguishable from slate or other materials. It's a great idea to get a metal roof first then solar. Even the cheap ugly metal roof since the large ridges are great for attaching solar panels. Then in 20 or 30 years you don't have to remove the solar panels if you need to upgrade the shingles if you have metal roof.
