Metal roofed houses in South Africa are very common. They act like a Faraday
cage and blot out all radio signals. But you can still get reasonable
reception on a portable if you put it against a window in the direction of
the signal you want to hear. Mostly though you have to put up a decent
outside antenna higher than the metal roof (and away from it).

Any SWL's listening from a building with a metal roof? I'm
considering putting a metal roof on my home. Central Alberta, Canada.
Hot summers, cold winters, fair amount of wind, electricity . . . . .
I'm wondering what the considerations are (if any) as to how the roof
may impact SWL'ing. Installers suggest no reason to ground, no
lightning issues, no static issues.
