I found a link to start with:
Code-Compliant Installation of Lightning Protection Systems | UL Solutions |
The national standard on lightning, NFPA-780, permits either aluminum or copper braided cable with typically 28 to 32 strands. Copper is a better conductor. If you have to remove the system to re-roof it can be re-installed. This may or may not be true for aluminum depending on the age. If you have a lightning system and need to re-roof have your lightning system installer lay it back and then re-install it after the roof is completed. This is not the job of the roofer.
