Default Grounding a metal roof

I am having a metal roof put on the house and shop. The installer said it
isn't required to be grounded. The city inspector said the same thing. Is
that really true? I'm thinking of running a #8 from the roof to my common
ground. Does that make sense?


Hi Joe,

It is arguable that the entire roof would even be evenly conducting,
as installed. As conductivity is not a primary concern, the installer
is not motivated to insure that a #8 wire attached to one panel would
be felt by any other with any degree of confidence. Further, even if
all panels exhibited continuity today, this is not to say they would
tomorrow unless some care was taken to insure tight interconnections.

It is not unheard of here in this group to find Hams taking that care
and bonding all panels. The sense of it is to reduce the chance of
developing spurs due to RF currents meeting corroded joints (although,
no one has ever reported this as a problem, only anticipated it).
