Around 1900, there were lots of ¡°Lightning Rod¡± salesmen traveling in the Midwest selling their pricey systems to home owners. Lots of lightning related house fires pushed many home owners to invest in the systems. It appeared that the rods did some good. Only problem was that many of the systems cost 10% or more of the cost of the home.
My personal experience was having and Alpha Delta 160/80/40 dipole get a hit. The coax had lightning protection at the house entry but the center insulator was blown apart and the inductors on one side were blown apart and the copper remnants were all twisted and were all over the roof.
That electrostatic discharge stuff can get ugly!

?Hello--
Here in rural NH, many houses feature what's called "standing-seam steel" roofs
because they're better at shedding ice and snow buildup than shingles
or (Heaven forefend) slate roofs.
When we reroofed our house with steel, I asked the roofer whether the roof should be grounded.
The roofer didn't know and never heard of such a thing.
Comments are welcome.
