We really need automated roofing. Installing shingles is easy, except that it has to be done on top of buildings. There's an experimental roofing robot, but it's not good enough for production yet.[1]

Metal roofs seem nice and easier to install too, but at least where I had a house built (Ireland) the local planners (aka meddling old people with too much time) thought it wasn’t suitable for a “home” so you had to spend four times as much on a slate roof.
