What can i do with peeling sheetrock on the walls?

Why is it peeling?

1. Determine why it is peeling and fix the problem: water, humidity, wrong paint used etc.
2. Scrape the peeling parts.
3. Sand to even out.
4. Fill with drywall compound if necessary.
5. Prime with a high adhesion primer.
6. Paint.

that sound like a moisture issue...

First, why are they peeling? If a moisture issue, you need to find the source and fix that first, along with any mold issues. If peeling due to poor maintenance or wallpaper being improperly ripped of the walls, I would just replace the sheetrock.

I agree with Dfm, drywall shouldn't peel, so you need to find the reason is happening
