Help me recreate a HF antenna I made 35 years ago

So time to get back on topic... antennas. It seems my original "rotatable dipole" is not practical for my situation (metal roof) but I'm still going to build it anyway (I don't give up that easy) Looks like my best option is a 1/4 wave vertical mounted on the "peak" of the roof (simple lightweight design using wires for the element and some "radials" (scroll back up and see the photo I posted) I have lots of 16 ga speaker wire and an old (but long) fishing pole. Two questions:
1. would there be any advantage to running 2 wires up the fishing pole (or is 1 fine)?
2. I can have two radials (full 1/4 wavelength each) run along the "facia boards" next to the roof (they will obviously angle down a bit) Also, I will have one radial going from the antenna to a fence (might use a simple rope/pulley/weight setup so it doesn't snap under tension) Finally, just for good luck, I will connect a magnet to a fourth radial wire and "toss" it over the roof (fingers crossed) Is there any advantage to electrically connecting the radials to the metal roof?
I can't walk on the roof (long story) but we have an extendable ladder. The mount will be made of wood (have lots of scraps) Basically, it won't cost me a dime except for the coax. I'm also going to have a ground wire (something heftier than the speaker wire) running down to a water pipe (I know that's not "proper" but still better than nothing) This is kinda a "if you can't beat 'em, join 'em" mentality (with the roof being the enemy) I am loving my new radio and studying for my technician license but for now enjoying the CB (11 meter)

I could use the copper pipe I have for the vertical element but it will need more support . Would it be that much better than wire? I was saving it for the horizontal dipole project (or even some VHF J pole antennas... side topic) Keep in mind I am not using high power.

This should also make a good receiving antenna for 10 meter band

Please understand that everything I'm doing with antennas is experimental (temporary) I'm just testing different ideas. If I wanted a long term solution, I would save up for an A-99

Something crazy happened yesterday! Before I tell you, let explain something. I'm in a odd living situation... live with my mother and my nephew. My nephew's room is next to my room (and my mag mount antenna on the metal tool shed is just outside his room) He plays electric guitar and has all this high tech stuff (including a connection to a computer for recording) Lots if wires everywhere. I was talking on my CB radio and he ran into my room and said "you have to hear this" He had been recording and somehow could hear my radio through his setup (all those wires are like antennas) We both got a laugh but then I realized this is going to be a big problem! I'm hoping that having my 1/4 wave antenna above the metal roof will block signals from reaching his room but it might not matter. Good thing he mostly does recording on saturdays. He has never mentioned hearing my radio before (when just playing through his amp) so not sure what is causing this only when he has his recording setup connected... any guesses? I remember when I was young, the guy down the street had an old tube linear amp but it was 1000 watts and most likely had issues. Many neighbors said it was messing with their TVs. I wouldn't think a modern radio wouldn't cause this kind of interference.
