The building codes define the differance at 2/12 or 2 1/2/12 however it truly depends on the product. Remeber unlike asphalt shingles there are many varied styles and systems available in metal.
Vertical rib panels can go as low as 1/2/12 however they have a higher rib/seam. The longer the roof rafters, the more water it must deal with as well.
Pick a sytle from one of our members on the site, then contact them and ask about the limitations.
