>As an owner, if you intended the spend the money for 50 year shingles just get a metal roof instead. As a builder they make no financial sense.
True, metal roofing is preferred, BUT if you live in a high snow area it needs to be carefully considered if it will actually work for your house due to snow/ice sliding.
Chimneys? Vent pipes? Gutters? They may get ripped right off.
Roof above another roof? Expect some big dents in the lower roof.
Then you need to invest in snow stops which is another can of worms where a lot of things can go wrong if improperly designed/attached.
In that case a 50 year shingle is a better solution.
They do make "stone coated? metal these days, which may provide enough friction to stop snow sliding, but I don't know.
