Leaves wrinkling

[Ben_in_North_FLA]

looks like your bark is totally dry and not retaining water. When you have limp leaves in a plant always look at the roots *orchid health always starts at the roots", either dry or rotted roots cause the same problem.... no water to the leaves and leaves start to wrinkle or limp.
You need to re-hydrate your media, this means soaking the pot in water with some kind of weight keeping the bark from floating away. I would also consider adding some water retentive media to pot... maybe some sphagnum moss...
When the media is wet, lift the pot and feel the weight. This will be the best way for you to tell when the plant need water, that is when the pot is lighter in weight... hope this helps.

So are the air roots supposed to be silvery? And should I try to redirect the air roots slowly into the media?

All the roots are silvery when dry, and all the roots turn green when wet. Let the air roots go where they will. When you water, be sure all the roots are wet. Some of us suggested soaking all the roots and pot in water for hours to water, so the plant can take up more water.

I’d also recommend watering by soaking and if there are no in bark roots you can see through the pot, use a skewer too. Do the plants wobble at all? If they’re loose in the pot due to lack of roots, carefully staking the plant (insert a stake and tie the plant to it) can help. This way the growing root tips won’t rub against things and get damaged if you handle the pot. You can also mist any above media roots daily or whenever they’re silver. You should start seeing some improvement within 2 weeks.

Air roots can be redirected into the media if they’re flexible enough, but a lot of times they’re too brittle. If you have one you can get into the bark, I’ve used a small rock to keep the root down. The rock may have to stay until the root starts actively growing (sometimes months).

That is not root rot (or does not look like it from the photo), that is dry roots caused probably by overwatering, but also because combined winter cold weather and too much water is a combination many orchids cannot take. Not all brown on an orchid is "rot." Even though they are brown, if they are still "hard" that is to say, seem like a vegetable like a green bean, then they are taking up water. Roots have a life cycle, and these are at the end of theirs. To get the leaves from being wrinkly (which is being caused because they are not getting water--yes, from the old roots), what you need to do is either soak the root area for about 20 minutes per day, or bag and sphag if you don't have the time. You may need to repeat this for a while. You need to get new roots growing from the "root zone."

Soaking like that doesn't cause root rot? I have moisture in my pot still from the soaked bark I used to repot. So i shouldn't water or soak right away right?

If your roots are silvery or white, you can water again. Roots don't rot being submerged in water for some hours. They rot when they get no air for a long time.
