OP says he'll be in the house ten years, maybe more? Go with a 20-year asphalt and leave the metal roof decision to the next guy!!
The low pitch is hard on the shingles, but a fresh, single layer install should last longer than 10 years. Second and third layers do not last as long as the first layer. I have a low pitch 2/12 roof with shingles, and we're on year 13 (single layer) and it's looking good. I do go up several times a year to clean off debris and moss--easy to walk that low pitch safely.
We asked our installer about a rubber roof because of the low pitch, and he said shingles would still last longer. IIRC, expense would be a wash in the end. Rubber roof is ugly on a pitched roof.
Tear-off does add to the expense, but it's a routine maneuver that a good roofing company will do pretty quickly and cleanly.
