Car headliner repair can be a simple, quick, and inexpensiveDIY project. Learn five different methods.
No matter how well a car is made, something on it will break or stop working properly eventually. The headliner is one such part.
If you’re dealing with a sagging headliner, don’t worry. AutoTribute has you covered.
Not only will we provide you with ways to fix the headliner yourself, but we also explain just what exactly a headliner is or does, why it fails in the first place, and what you can do to maintain it. Let’s begin.
What Is A Headliner?
With regards to automobiles, a headliner is a fabric or other composite material that lines the inside of a vehicle’s roof. It has several purposes:
Headliners improve the appearance of the interior, giving your car’s otherwise dreary fiberglass or metal roof a soft, nicely textured, and colored surface that’s more appealing to the senses.
They prevent the interior from getting too hot or too cold by providing insulation against outside temperatures. In other words, the inside of your car is kept cooler in the summer and warmer during the winter.
Headliners improve the acoustics of the interior and make it quieter by absorbing outside noise.
They act as a cushion against head impacts during collisions, helping mitigate injuries.
As you can see, car headliners contribute a lot more to our driving experience and safety than they are often credited.
Why Do Headliners Fail?
A headliner is not a single sheet of fabric but rather a multi-layer composite material that’s glued to polyurethane foam, which in turn is glued to the inside of the car’s fiberglass roof.
The cause of a loose or sagging headliner has less to do with the composite material and almost everything to do with the glue that sticks it to the roof. The following variables are usually at fault:
Old age. The glue deteriorates over time and becomes less effective at holding the headliner composite in place.
Moisture. Exposure to any form of water, especially moisture, will cause the glue to moisten and dissolve, accelerating its deterioration. Humidity is a serious risk factor.
Bad glue. While usually not the case, the adhesive might not be of good quality.
The headliner will initially start to sag as the glue deteriorates and then fall down completely if the condition gets very bad. Not only is a sagging or falling headliner a potential safety hazard that can cause you to fail a vehicle inspection, but the unsightliness of it will also reduce the value of the car.
Of course, you shouldn’t wait until things get that bad. Take action to repair your headliner once you see signs of deterioration.
