Repairing a ceiling of unknown construction
I have an older home, most likely constructed near the end of the 1950s, which has some ceiling issues. The roof leaked and left damage in a room. I am trying to identify this material so i can begin repairs. Underneath the skinny pieces appears to be sheets or sections of the material. I haven't disturbed this, however, a friend tells me it feels like cardboard or something similar. Another person suggested it might be paper tiles. Your help is greatly needed!

That would not be a builders ceiling. That would be a ceiling installed at a later date.
It looks like some type of 2x2 glued up ceiling tile.
Could be some type of cellulose.
I'd try removing one to see how well it's glued to what may be plaster behind it.

That is an excellent question. I hadn't thought of that and I cannot answer it.
I don't know if asbestos was ever used in those types of tiles.
Are they 2'x2' in size ?
Hang tight..... the other guys will stop thru and they may know.

I can't answer if there is asbestos involved but asbestos is basically only dangerous in dry breathable form - like when you sand it or otherwise get it airborne. Keeping it damp goes a long ways toward alleviating that concern!
I'd tear out what needs replacing and go from there. If nothing else the texture can be replicated over drywall.

Today I cut a piece of this and was surprised by what I found. I cut a small piece for inspection and found this to be very similar to drop ceiling tile. The panels are nailed to the beams then there is a strip covering those nail holes. The thickness of this is about 1/2". It appears as if they rolled drywall mud all over it. The panels measure 4 feet in width and varies in length since they used 3 pieces to make each section.

Another creative use for acoustic ceiling tiles.
But what is more important.... what's behind it ?

The attic and insulation. It's not a 2'x4' tile either. There is another name for this, and I totally baffled the guys at Lowes with this one. Sure would like to just put in something that was the same but I gotta know what this is first.

The only thing I can think of is Homasote.It's a sheet goods product that can come like that.
Certainly not what I'd want for a ceiling.

Anyone have an idea of what this could be? This is a house built sometime in the late 1940s or 1950s. I am completely baffled by this material. In another room where damage occurred they replaced everything with sheetrock. I'm just trying to repair the room so I don't have to do the entire thing.

Oh I thought it was four by four squares was actually 4 by 8. They just used the piece of trim or lattice put the squares in place. But the material had no designating marks or anything to say what it was. It was up there like they had used it instead of sheetrock. So I ended up taking it down and putting sheetrock in its place. I only want it to repair the small section that was damaged so we left the other intact. I just wish I knew what this material was. It's like paper or cardboard or something of that nature

This is a picture of homasote. It is used for pin boards, ceilings (not sure why) and sound barrier situations. It looks as if that is what you have. Now that you know, and you have replaced it, what?

Nothing wrong with replacing the cellotex with drywall, it can be textured to make it more resemble the other boards. Since drywall is heavier it does need to be secured a little better than cellotex/homasote.
