Roofers caused an issue for me...

I had a roof replaced and they weren’t being careful when tossing the old material down and it fell on to my solid tarp pool cover. That included nails and shingles... I noticed water was pooling on the top and then I saw there were two dime sized holes and and one half dollar sized hole.
I need to replace the cover, but I’m concerned about nails that maybe have fallen thru the holes and could damage the vinyl liner. It is getting cold up here so I don’t have much time so I was going to try and get the cover off on Friday, and then see if there is any debris at the bottom. If there was, I was going to hire someone (at roofers expense) to vacuum it out. However, there may be some time that elapses between the time I take cover off and they can come out. Will leaving it uncovered in freezing weather damage the vinyl liner?

Leaving it uncovered isn't a problem. Covered or not, pools freeze. The cover is there to help keep debris out.

Having nails sitting on your liner and rusting is a bigger concern. They're not going to replace your liner over a stain. I would get the cover off and get any nails out ASAP. Don't worry about who "should" pay for it, just take five minutes and fish it out with a magnet on a string (safest) or leaf rake (be careful not to push into the liner).

They use a magnet to get them out of flower beds etc..Maybe they can use it to get any nails out of the water? Might be better then running over then with a vacuum.

I don’t even know if there are any down there, my main concern at this point is taking a pool cover off if there is freezing weather and if that would be bad for the vinyl liner

The vinyl doesn't know the difference yes cover or no cover. The main thing is do not disturb the ice once it forms on the pool surface as it can be sharp and cut the vinyl. If you have a robot let it work the pool floor.

You can patch the holes in your cover using wide tarp tape or duct tape on both sides. I patched holes in my cover from rodents and it has lasted years. See the grey patches below...
