I don't know if they work. But, some of the buildings at work
(NASA Johnson Space Center) have spikes along the roof edges.
Also, at Houston Zoo, the Brown Education Center, among others
there, has spikes all around the roof edges and along the roof peaks.
And didn't a lot of the barns of yesteryear (or maybe even this year)
have pointy tipped lightning rods at their peaks?
It seems to be an idea that is pretty deeply entrenched if it doesn't
work.
