As a kid in the 50s our house and grandparents house next door got hit at least once a year. Our house once hit by ball lightning, my brother and I saw it and it caught his mattress on fire. Then Dad & Grandfather put lightning rods on both chimneys. Never a single strike now in almost 70 years, either house.
My house here on a hill I had problems until I put lightning rods on both chimneys, never a problem since.
I used copper for everything. I made rods with 6 foot 3/4" copper pipe, sawed upper foot or so rolling then soldered them into points.
Then put antique amethyst balls on them. There're strapped to chimneys, two each copper straps. Clamped and soldered on flat copper woven wire running under shingles, connected together then down to three driven copper ground rods. One was already there from telephone service which this one goes under house bare copper wire to power company ground rod...so it's well grounded.
