We recently bought metal roofing for a pavilion we are building. This was the Galvalume (not colored) and R panel (exposed screws). It was fairly heavy duty 26 Gauge thickness. They cut it to our specified lengths. The cost was about 60¢ per square foot.
Some of the suppliers we checked would not provide it to our specified lengths, which would have caused waste, and increased the effective cost per sq. ft.
I re-roofed my house with the same type metal roofing 3 years ago. Shortly after that we had a major hail storm and I did not find any signs of damage, while many shingled houses had roofs replaced. Our next house will definitely have the metal roof.
