How to fix your sagging headliner?

1. If you notice the headlining coming off the edges, you can use glue to reattach it. It would be best if you used the right glue, which is meant for this specific use. It is best to get it in a spray can. This will ensure that you can get an even coating of glue. However, in order to this, it is recommended to pull the material off the canvas and re-glue it. More often, it is just best to replace the entire roof liner with new material and glue, because who knows how well the glue will stick to the old existing layer of glue. Professionals will usually remove the old glue and replace with brand new glue and material. 

2. Do not use any home remedy techniques- this includes the use of tape, stapling or pins. If you were to get into a car accident those pins are going to come loose and become a dangerous hazard. The last thing you want to happen during a car accident is find yourself caught in the middle of a scattered and flying shards of pins. Not only this, pins look super unattractive – if you are planning to fix it, do it right. Hairspray is meant to keep your hair intact, not your roof lining, yes it may be sticky, but it will just not do.

3. Stay clear of applying too much pressure or steam, for those who use a steam cleaner. Yes steam is great at melting the glue, but you do not want to expose water beyond the lining material and onto the foam and 

How to Fix a Sagging Roof Liner

The fabric headliner in your car or truck offers insulation, soundproofing, and a stylish touch. Headliners usually match or accent the interior color and need little care or maintenance. But unfortunately, headliners can sag over time. Then, that elegant headliner starts to look old and ratty.

Here’s the good news: It’s easy to repair.

Why Headliners Sag and How to Repair It

In many vintage cars, metal bows suspend from the roof to attach a cloth headliner. The fabric is typically sewn in pieces—with the seams attached to bows. The metal bows run across the roof of the car, from side to side. The fabric attaches to the bows.

Modern cars typically have the headliner fabric attached to a solid piece of sturdy plastic or fiberboard. Usually, there is a thin layer of foam between the fabric and board. Some manufacturers include material above the board to help insulate the car and provide some soundproofing.

The adhesive used to attach a headliner cloth doesn’t last forever. The glue stops adhering due to prolonged heat, moisture, or aging. Also, if you consistently drive with the windows down, the edge near the window’s edge can come loose as the wind buffets through the cabin.

Sags from the Edge

If your headliner is sagging from the edge, there are more ways to fix it. Some cars have a plastic edge piece that butts against the headliner, which can be removed, allowing you easier access to the edge of the fabric.

Permatex and 3M, among other companies, sell adhesive specially designed for headliners. These spray on clear and won’t leave a visible residue discoloring your fabric.

When spraying these adhesives, use gloves, a facial mask or respirator, and work in a well-ventilated outdoor space. Make sure there are no flames nearby as the spray is highly flammable. Lightly spray both the fabric and the backing board with the glue. Wait a few minutes and apply a lighter second layer. Wait for an additional two to three minutes until the glue is tacky.

Then, lightly push the material onto the backing board starting- from the center section. Use a wide piece of cardboard or paint roller to help apply even pressure and smooth out wrinkles as you go. Let the glue dry with the windows open.

Sags in the Middle of the Roof

For a saggy middle piece of fabric, park the car in the sun to gently warm the interior. Then, use a steamer or an iron to heat the material (and hopefully reactivate the glue).

Lightly push the fabric onto the support board.

Use a wide piece of cardboard or a paint roller to smooth the fabric onto the backing. If the fabric sticks, consider yourself lucky. If it doesn’t, you will probably need to see a car upholstery shop or consider removing the whole headliner and applying new material.

Start Over

If you can’ easily apply the glue to all the sags, consider removing the headliner. But, first, remove the dome light and other devices attached to the headliner.

Using a set of interior trim removal tools, remove the backing board in one piece. At that point, you can either loosen the fabric to the area where the sag ends and then re-apply the adhesive or remove the material entirely.

Alternatively, purchase an entirely new piece of matching fabric. Glue the new fabric to the support board (which was removed) and allow it to dry. Then, you can return the headliner to the car and re-attach it.

Regardless, don’t wait too long to repair a saggy roof-liner. The problem often gets worse if ignored.
