My GPS18LVC works through a standard US residential roof. But you
probably have lots of metal in the way. So ... YMWV

You can extend the serial cable between the GPS and the host system so
that you can place the receiver where it has a sky view. It may also
help to place the host system in a location close to the roof. If you
use a small system which can run off of POE that will simplify the
cabling a bit.
