How to fix ceiling that has dropped over garage door?

[mills28]

Hi looking for a quick fix for part of garage ceiling has fallen over roller door. Probably due to vibration of door going up and done everyday. Any ideas looks like it needs lifting back up maybe glueing the rest of the carport is ok.

Hi @mills28,

Is it just the cornice that has moved? Or is the plasterboard as well as the cornice?

If it is just the cornice, then you can grab some liquid nails, open up the crack at the top a little bit and pump your adhesive into the gap. You could then grab a piece of timber long enough to reach the floor to wedge it up in place. Make sure you wipe off any excess glue that seeps out of the gap while it is still wet. 

Once the glue has set, give the crack in the cornice a quick sand with a sanding sponge to smooth it out a little bit, then apply No More Gaps to the top edge of the cornice and the crack, smooth it off, then paint over the top.

If the plasterboard has dropped, start by locating the two nearest framing members using a stud finder, then drive a plasterboard screw through the plasterboard into each of those framing members. Keep adding screws along these members until you are happy that the plasterboard is well fixed in place. You will then use Spakfilla Rapid Gap Filler to cover the screws, give them a light sand and then paint. You would also follow the same process described above to fix up the cornice.

Let me know what you think and if you have further questions, please don't hesitate to ask.

Hi @mills28 

Looking at the photo I would say the roof sheet has dropped, which is why the cornice is only slightly cracked. This is evident when you follow the line of the brick mortar line.

A few months back I had to resolve for a client the same issue albeit the ceiling was hitting the roller door. Basically the plasterboard didn't have enough or any stud glue to the truss and overtime the screws couldn't support the weight of the screws.

If you have a tiled roof, you will need to remove a few to access the area above to see if this is the case with yours. More involved if your roof is colourbond as a sheet and top flashing will need to come off.

The batteries in the stud-finder were flat (of course) so, I then knocked through the top of the roof sheet a few thin nails to mark where the joists were from inside the garage. Then I applied a stack of stud glue in various spots where it was missing.

I had already prepared (and this is what you can use a temp fix) a T-prop. Which I first rest up against the dropped section of the ceiling and then tapped it at the bottom with a mallet into place. The T-prop was slightly taller than the internal height of the roof so it pushed the sheet up.

This made a few of the old sheet screws popped through incorrectly. I put new screws in and patched the areas of the old screws. Put the roof back together and left the prop for a few hours and the job was done.

I had the timber to make the frame. But you can hire an Acrow-Prop for less than $10/24hrs. You will still need an off-cut of timber to rest across the top so the top of the prop distributes evenly. The timber yard usually has free off-cuts.
