Reply #7: We're going with metal

[madokie]

but when I first done the part where we had a leak I started with blue and at the time there was no tax write offs offered, since if you now use white, metal or whatever roof you chose you get a 30% tax write off.
I like the look of metal roofs and I like the longevity of expected life times. I'm 63 so I doubt I'll have to worry with the metal roof in my or my wifes lifetimes. Thats what weighs heavily on our decisions when we do things as we get older as we know that the day is coming when we'll both be on a fixed income and we don't want to be hit with a big new plumbing, electrical or roofing need or for that matter our appliances either so we're buying for quality where we can.

I suggest metal to the OP as its pretty much permanent as human lifetimes go.
In my travels I've also noticed that really old houses that have had a metal roof from the get go are in much better structural shape now even if they've been unoccupied for years. Metal will get my vote every time.
