The headliner usually sags because the foam layer between the fabric and the hard shell has deteriorated and allowed the fabric to separate and droop. Unfortunately, the fabric cannot be re-glued to the shell, because the crumbly foam just will not hold the weight of the fabric. You need to remove the shell, scrape off all the old foam, and glue a new piece of headliner fabric onto the whole shell. Headliner fabric can be found in many fabric stores, it is fabric and foam glued together. If you are going to attempt this repair at home, make sure the glue you choose will stand up to the high temperature generated by sitting out in the summer sun.
If you go to Napa they sell push pins to hold up sagging headliners.

Once a headliner starts drooping there is nothing you can do to fix it. You can temporarily find solution though. I put thumb tacks in mine, they keep coming down every now and then though, you just need to push them put in. You could also staple it to the roof(not recommended). The ultimate solution though is to buy a headliner kit for about $30 and replace it following the instructions. You can get things at a craft store like joanne fabrics that work fine and never fall out.they have like a clear button with a tiny like corkscrew on them so all you have to do is turn them in,they really work fine.hope this helps. The proper fix is to find foam backed headliner material at a fabric store. Take the trim out and take the headliner board down. Clean it and remove all the old foam. Put on the new fabric and reinstall in car. optionally, you could remove the headliner and pay an upholstery shop to reline the fabric or, if you've got plenty of $$$ buy a whole new headliner from a dealership I have repared many sagging and drooping headliners with little expense. You must carefully remove the trim that holds the headliner in plaace then remove the headliner. They DO come out of the car when you figure out the angle it must be in. Be careful not to bend it. Once removed, carefully remove the material. If it begins to deteriorate, the headliner material can be purchade custom cut and fit from outlets like J.C. Whitney. Use a srpay adhesive like 3M and LIGHTLY spray the surface that the headliner material goes on. Center the material and smooth out from center to edges using your hands or a 3 or 4 inch paint roller until it is smooth and fastened. Let it set for a few hours for the adhesive to cure. Then reinstall the headliner, trim and anything else you removed. If done properly, it will look like new. Be patient.

PLEASE NO! Dont do this! I have an custom auto upholstery shop and this is always an issue when people attempt to fix their own headliner. Let me explain, In most modern vehicles there is a headliner board and to this board a foam backed cloth is basically glued. As time passes the foam backing begans to die, for lack of a better word, and when this happens the cloth begans to sag. If you should choose to use spray adhessive to bond the cloth to the board it will not look well and it will make it very difficult for your upholstery guy or girl to properly prepare your board to be recovered the correct way. At some point the intire headliner board will have to be removed and covered with new material. If you try to fix this yourself with spray adhessive and your old material you will only cause more work for the proffessional upholsterer and that will amount in more cost. Most headliners can be recovered for around $100.00, of course the cost goes up if you have a sunroof or T-tops, etc. You would be much happier spending the money to have it done by a proffessional. If you are in the Souther Indiana area I would be happy to take a look at it. just email me Yes - It worked for me on an older vehicle and it looked alright - a can of glue is cheaper than an upholsterer. I live in Canada.
A sagging sun visor on a '04 Toyota RAV4 cannot be reasonably fixed by yourself. You're better off buying another one from the dealer or a junkyard.
I have a great door seal that will help fix most garage door problems. It is called a Snirtstopper. Take a look at it at Snirtstopper.com Thank you, MB
The trim around the headliner needs to be removed. The trim holds the headliner up. Be careful during removal not to break the headliner backer.
