Popcorn ceiling with damaged bowed drywall.
The roof vent leaked at one time causing the ceiling to bow slightly

The ceiling of the affected area is bowed and also has popcorn finish that needs to be removed. Is it possible to place new drywall over the entire existing ceiling without removing the old, so that the insulation in the attic does not fall down?
You need to make sure there isn't any moisture and it's completely dried out.
Hi Jean. I would replace it all. There could be mold on the existing drywall. I had the same thing happen and removed the water damaged drywall finding out that there was mold on the other side. Good Luck.
Hi Jean,
The first thing you should do, in my opinion is check the popcorn ceiling and the insulation above for asbestos. If your house was insulated and the ceiling was done before 1973 it might contain asbestos. Check at your local hardware store or even Walmart for the kit to check.
If there is no asbestos, then if you want to take the popcorn ceiling down, it can be done. When did our popcorn ceiling, we sprayed it with water and then gently scraped it all off. It can make a mess, but we learned from the pro's who had done it before. We taped thin plastic drop cloths to the top edge of the wall next to the ceiling, then we put more on the floor. When it was time to clean up we just wrapped it all together. It made it easy to clean up the mess. Click below to see how someone else did it.
As to replacing the drywall that is on your ceiling, that depends on your skills. My first hubby & I put up some drywall on our ceilings but if you look closely, you can see that it was an amateur job. It's not bad and it's in an upstairs bedroom that most people don't see and those who do probably wouldn't see it, but if it's in a room you are using all the time, your skills will be important.
If there is asbestos or if you aren't sure that you have the skills to put in the new drywall, you should hire a professional. This is especially true with the asbestos, if it's there. Do not try to remove asbestos yourself. Wishing you the best.
I assume you have painted the ceiling since the leak otherwise we would see the water damaged ceiling spots.
I can see no reason why a good drywall man can't add a new ceiling over the old ceiling.
I do not think it would be a job for the average DIY'er.
You can also put wood - planks or sheets that look like ship lap - over the popcorn ceiling if you don't want to remove it. A sheet of wood laid over the ceiling should also cover up the bow in the ceiling.
Hi Jean,
How much clearance do you have in the room - floor to ceiling?
The reason is this, the best way to put new drywall ceilings over old is to use 3" x 1.5" or 4"x2" (75mmx35mm or 100mmx50mm) timber fixed to the existing ceiling as battens, which will stay flat and easily span the room, fixed at either 16" for 3/8" (450mm for 10mm) drywall, or a maximum of 24" centres for 1/2" drywall (600mm for 13mm drywall ceiling boards)
The total depth of loss of ceiling height will be around 2.5", so on a tall ceiling it's hardly noticeable.
You can coat your roof with EPDM Liquid butyl rubber that has over a25-year history of success in roof restoration and can be used on all kinds of roofing surfaces or styles. EPDM coating will give you better insulation and a watertight, airtight, highly flexible smooth seamless membrane exhibiting a new, aesthetically pleasing look for a fraction of the cost of a new roof. Butyl Liquid Rubber is a solvent based, one coat rubber roof sealant that provides an insulated barrier from external damage to the building.
Yes, you can. We just did that in our bathroom. However, we decided to go with beadboard rather than sheetrock. You may have to "strip" over the ceiling so the new sheetrock has boards to grab onto.
Also, make sure to have the popcorn tested before removal.
