I've got a wooden house. A new roof has gone on. After the removing of solar hotwater pipes, there is no longer any path to ground from the corrugated steel roof.
(How do I know? One of the screws cut into a cable and electrified the whole thing. No RCD tripped. Golly.)
Would you strap it to earth? To a sacrificial anode? Neither? What reasoning please? We live on top of a hill and have lovely thunderstorms.
