What you might do is if you have any molding around the ceiling seams is remove it and then check for clearence and shoot some ss staples around the edges and corners to tighten it up once it is good and tight reinstall the molding.
Rv slide out roof sagging.
As the top of the slide touches the side of the trailer there are about 2 5 inches at the bottom that need to be drawn in yet.
There also may be an internal fault in the controller.
This may take some time to track down due to the amount of wiring slide outs have.
On occasion the roller tube can become slightly bent allowing the middle to sag.
If you have a roof that is sagging on the inside and it passes all visual inspections from the outside you should take a second look at the air conditioner.
Each rv roof top air conditioner has a gasket underneath between the ac unit and the roof and these can sometimes develop leaks even on fairly new rv s.
Solved the sagging and after a few minutes of adjusting the other rollers i had the slide out working smoothly and sealing completly.
If the fabric is stretched the best fix is to replace the fabric.
The slides seem to be tilted inward from the top too much in my opinion.
Lastly another possibility although a bit remote is that the room is out of square and one side is extending further than the other.
If you suspect that there is a leak somewhere in your rv s slide out make sure to treat both sides of the slide out s old seal with a new sealing solution.
One of the signs that comes with a blown fuse is that there may be a short in the wiring at some point.
Now the roller assembly bolts to the steel bracket rather than the floor.
The floor of the slide inside the trailer kicks up about 2 inches as the bottom is drawn in.
There are many sealants that you could go for out there so do some more research to figure out which one is right for you.
I removed the rollers and fabricated a steel bracket that i welded to the existing cross bars of the frame.
