Asphalt no brainer unless you selling a really expensive house and the metal roof is the norm or you selling a house that is modern and a metal roof is needed to complete the look.
What are your plans with the property? If you are selling it, go for asphalt. Metal roofs require regular maintenance. If this is your forever home, go with metal.
@Asher Knudson- I would go asphalt. I bought a rental with a metal roof already installed less than 10 years ago, it looks like due to weather in Rochester, the seams have popped open and the previous owner used Caulk to seal them. Now I've had a couple of contractors come out and they said they can either re-caulk for a temporary fix but recommend a new roof. The company that installed the roof went out of business so there is no warranty to cover the repair. I know this isn't typical and if I were doing it myself would've picked a company that's been in business for a while, but something to think about.
Good of it is I got a discount on homeowners insurance for having a metal roof(very small). I would say don't waste the money on the metal roof. If it gets damaged and the warranty doesn't cover it or something similar to me happens you won't really get to realize the savings. So at the end of the day it depends on if you're keeping or selling it but more than likely the asphalt makes sense.
I have had two metal roofs installed and have been pleased with both of them. Both contractors have been in business for a long time, and have good references. I was most concerned with quality workmanship and good references, than I was about the price. I would also ask them the details of their warranty before you decide.
Sorry for posting to old thread. If you happen to see this please
In my case with 12 unit apartment building my metal roofer is $6000 less for metal roof vs shingles. He is ofcourse $3000 more on gutters compared to another roofer.
I am going to ask him formal written quote. So I can trust him. The contractor quoting $6000 less for metal vs shingles is very highly ranked in angies list and also verified installer. Not a national level company though. So warranty may be an issue.
Shingles fellow quoting for gutter and roof : $32,000
