Sagging Headliner

Dealing with a sagging headliner while seated in your vehicle may be bothersome, but quick solutions are also available. To fix the sagging headliner in your car, you may employ tools such as steam cleaners, paint rollers, double-sided tape, glue, clear-headed twist pins, and sequin pins to rectify.

Fixing a sagging roof lining of your car without the need for removal can be done through one of four methods: reattaching it with adhesive, applying double-sided tape, securing it to the car’s roof using pins, or utilizing a steam cleaner along with a paint roller.

This article mainly explains the different methods to fix a sagging headliner in detail.

What is the Headliner?

The interior roof covering in a vehicle, referred to as the headliner, serves both visual and functional roles. It improves your car’s style. The headliner also plays a vital role in insulation, shielding the cabin from external temperatures and minimizing vibrations to reduce driving noise.

Beyond its fabric exterior, the headliner typically contains multiple layers. The initial layer is made of foam, fiberglass, or cardboard, providing structural support. Atop this, there’s a layer of vinyl, leather, or cloth, which is prone to sagging, particularly in the old vehicle models. 

Causes of a Sagging Headliner

A sagging headliner is caused because of one or more of the following causes:

  • Poor Maintenance: The poor maintenance of your vehicle’s interior is one of the major causes of a sagging headliner. The poor maintenance may lead to the premature wear and tear of roof lining, carpet, and upholstery.
  • UV Exposure: The region near the windshield and visors is often the initial area where sagging arises, primarily because of heightened exposure to UV rays and sunlight.
  • Glue Breakdown: The glue failure is another cause of headliner sag, where the original glue securing the lining loses its adhesive strength over time.
  • Harsh Weather Conditions: Regular exposure to humidity, high temperatures, and adverse weather may lead to the deterioration of the glue holding the lining, diminishing its ability to support the headliner.

Ways to Fix a Sagging Headliner

Using glue is one of the most effective methods to repair a sagging headliner. But you may also use pins or thumbtacks. You may also use the steam or carpenter’s tape to sag the headliner. 

Follow the following famous methods to fix your sagging headliner:

1) Glue

The glue is the most commonly used method to fix the sagging headliner. Yet, the process may pose challenges, and success is most likely when addressing the sagging issue promptly.

Typically, the sagging initiates at the top of the roof, where the headliner meets the windshield, primarily due to prolonged exposure to UV rays. By using headliner adhesive readily available at auto parts stores, you may effortlessly reattach the headliner, particularly if you tackle the problem early on.

2) Steam

Using steam is debatably one of the most effective and professional methods to repair a sagging headliner without the need for removal. A steam cleaner is used to liquefy the headliner glue, ensuring its reattachment to the frame. Subsequently, a paint roller helps in ensuring the fabric sets up smoothly, devoid of any wrinkles or creases.

  • Initiate the process by testing a small section to check feasibility. Your glue shouldn’t be too aged.
  • Move the steamer across the headliner, similar to the motion of painting with a roller. Simultaneously, press your headliner back to the initial layer of material.
  • This approach not only reattaches the headliner but also diminishes the likelihood of wrinkles and crumples in the fabric of your car.

3) Staples And Hairspray

An unconventional yet effective solution involves using staples to address headliner sagging. This is also one of the most effective methods. Employ a stapler gun to fasten the headliner to the material beneath.

First of all, spray the hairspray onto the headliner and wait for a few minutes to dry it properly. As the spray is dried, an attempt can be made to remove the staples to observe the outcome.

4) Pins/Thumbtacks

Another method for fixing a sagging headliner is to secure it by pinning it back in position. For this method, use various pins, such as clear-headed twist pins, sequin pins, or pushpins. Simply insert these pins through the fabric layer into the foam backing board, restoring your headliner to its original appearance.

5) Double-sided Tape

Another method to fix the lining sag is to use the carpenter’s tape found in the latest toolboxes.

  • First of all, cut the required length of tape and affix it to the headliner.
  • Peel off the backing and secure it to the roof, addressing sagging areas without significant expenses.

It’s worth noting that this method may not be suitable if only the middle of the headliner is sagging, as an edge is necessary for tape application.

Headliner Replacement Cost

If the attempts to repair a sagging headliner prove unsuccessful, replacement may be necessary. The replacement cost of the headliner depends on different factors, such as your living area and your vehicle model. The average replacement cost of the headliner is from $180 to $520.
