What's hiding inside your headliner?

Took out the side rear windows and seals and found a heap of flaky stuff hiding underneath. Removing the C-pillar liner revealed a whole lot more. After removing the headliner the reason was evident. Roof rusting from the inside out!

It's my parts car Esty so it's not important, but still a surprise. I was thinking of keeping the roof if I (or someone) wanted to convert to a sunroof car later. I'll treat it if I decide to keep it.

When i took mine out recently, I had about 10 hand fulls of pine needles and paint flakes.

When I recently did my interior fully over I had a similar experience.

Is it just sunroof cars that are prone to this, or are non-sunroof cars getting this also?

I'm somewhat gun-shy to replace the headliner in my Blue car now. Not sure I want to know what's lurking under the liner.
