I have a steel roof, and I like its aesthetics. I have 14in. of insulation under mine, and I can only barely hear the rain. My sense is most people go for asphalt shingles because they're cheap, and they don't intend to live in their house for more than 15 years anyhow, so the next roof will be someone else's problem (too bad about the enormous piles of waste this approach generates).
