Fixing roof with impossible access

Well, here's funny story.
I have about 1500 if not more of cover over chicken runs. I got tired of walking in poop filled mud and made quick and dirty frame and covered it with yes, I know, Palruf. Yes, I know it's junk but it's chickens, right? Even that cost quite a bit.
After 2.5 years it is still holding but, after last Smowmageddon (or, Snowcalipsis, if you prefer) plastic sagged in some areas and, apparently, cracked around screws.
Resulting in dripping areas. I mean, it's still chickens, just gets on my nerves.
Of course, the worst spot is in the middle of that construction, so to get to it, I'd have to disassemble one side completely to replace sheet of roofing. Or, cover it.
To make things easier, entire roof and runs are covered in bird netting. So, sliding say a piece of new Palruf over the leaking area is rather challenging as I can vouch, how badly netting catches on anything.
Plus, if I slide 8 ft long piece over cracked area, I need to secure it in place somehow. I can get on ladder and reach maybe half way over it - after all, I covered entire area with netting in place - and secure lower possibly half of it to existing frame.
But what do I do with the upper end, where I can't lean over and reach to drive screws in?
And then I am guaranteed that wind will rip that loose end off. Last storm we had, it went to 60mph gusts, I still can't believe that plastic held through it.
So my question is - is there anything I can do to secure the UPPER end of 8 ft plastic roofing with it being slid onto existing roof and not being able to reach to it from the top? I have several spots like this, that need mending. Some are OK, 2 are really dripping down. Again, I can slide piece on top of existing roof, secure lower section of it - I am tall and have long arms - but I can't reach towards upper half of it. Has to be something that either cures solid later or else. I don't care, if it leaves smears on the roof, it's chicken run. But it has to hold very well.
I'll eventually remake it with Suntuf, if I spelled it right, as it's much stronger and you can walk on it. Just need to get by few years till retirement.
Any tricks, adhesives? Got to hold well because of the winds.

1500 sq ft of chicken coop roof ?
Personally I'd work on replacing the plastic with steel roofing even if I had to do it piece meal. What kind of roof structure do you currently have?

Was thinking.. maybe put wide strips of Liquid Nails on the repair panel inside, lift netting up as much as I can with head and shoulders, and bring it up and over the cracked piece as far as I can?
Problem is, after 2 yrs of service, one thing that roof is not - it is not clean. Not sure how well LN will grab.

Nahh, it's too costly to replace it with metal and we want something clear.
Yeah, I know. I easily guess, it's more than 1500sf. Just 4x4s as vertical columns, mounted on concrete blocks, with 2x6 as beams (?) and 2x2 as crossmembers.
I have no intenstions to build anything real solid and this light "cover" worked fine so far. Just need to mend a few spots.

If you can reach the upper end from below you could screw through the existing panel into the new one and caulk to prevent any leakage (as a supplement to the Liquid Nails proposal.) If you think the screws might pull out, you could consider using something like a molly or toggle bolt and lots of caulk.

Maybe drill holes in the existing panel to inject LN between the panels or big gobs of LN that the new panel will land on then use screws to draw them together.

How do you plan to keep water from getting between the old and new panels at the top?

Good question actually. Hoping thick strip of LN or sealant will do the job. I am not talking pouring down leak, it's more of a constant drip. Trying to seal it on the ground side of plastic panels so far does not give good results.
I can reach maybe half way up on 8 ft panel. That's it.
I knew it will happen, this material is known to crack but I simply could not dump big $$$ into something as trivial as chicken run cover. Of course, do over and $$$ is due anyway.

Attach a plastic angle to the top edge (with the panel below/inside the angle), hook it over the ridge, screw panels together from below or toss a tie-down rope over the roof and attach at both sides.

If really temporary use a blue or white tarp or heavy duty poly and tie down on both sides.

Thanks, john. I like your approach.
Well, I found where plastic was cracked causing that leak that irritated me. As it's easy access from underneath for me, I simply put a ton of Wet Or Dry sealant all over around it from the inside. if it'll minorly drip, I am OK with it. On humid days, it builds up condensation on the roofing inside anyway and drips in the morning all over. I'll see how goes it, rains return next week. Been weird weather - we jumped from Snowmageddon literally straight into summer. 75 outside.

If it is just a crack, duct tape might have been enough. Maybe duct tape over the sealant to stop any minor seepage.
