Well, Milo, in theory a metal clad/framed building would have that metal "earthed" (due to it being built on and into the ground) so that would turn it into a Faraday Cage of some sort. Signals would get out through windows and doors, but the metal would be likely to block the signal at every other angle. That's before we think of the signal attenuation due to it having to go through brick/concrete/stone walls.
PS. In THEORY, at exactly the right angle, you could reflect a signal off a metal clad building. Ain't going to be easy though.
