Anybody with lightning protection experience? I have a job coming up where I will have to run some #4 copper ground conductors on a pitched asphalt shingled roof from an antenna site installaton. I am thinking that this is done regularly with lightning protection systems and the same cable fasteners should work well for this application.
I see that there are basically only two types of fasteners- a copper loop or strap with a nail or screw through it and a square copper pad that gets stuck to the roof with pitch or adhesive. Problem is all the lightning protection systems I have seen have been on buildings with flat roofs and masonry construction so anything I saw won't really apply here.
I'm leaning towards the nail and strap with maybe a dab of sealant but I'm not liking that. Anybody done this before?
