Rudy N6LF has covered the top loading issues pretty thoroughly, see
Bottom line IMO: install as many top loading wires as you can as
horizontal as possible and then consider a loading coil.
I had eight 6' spokes of 3/8 Al tubing and a perimeter wire to resonate
40' of 3" irrigation pipe on 80m w/o any coils. Worked great on my
barn's steel roof.
