5 signs your headliner is on the way out (and why fixing it early saves money)

By the time your headliner is touching the back of your head while you drive, the foam underneath has been failing for months. The early signs are subtle but unmistakable once you know what to look for — and catching it early means a normal job, not an "I had to drive with the back seats down" emergency.

Here are the five symptoms we see week in, week out at the Massey workshop, in roughly the order they appear.

1. A faint "rippled" or "wavy" look on the roof fabric

Run your eye along the headliner from front to back in good light. If the surface used to look perfectly flat and now has a slight ripple — like water moving under cling film — the foam underneath is starting to break down. The fabric is no longer being held perfectly evenly.

Time you have: 6–18 months before visible sag, depending on heat exposure.

2. The fabric feels softer / spongier than it used to

Press the headliner gently with a fingertip. New (or new-ish) headliners feel firm — there's foam against board behind the fabric, so it has resistance. A failing headliner feels soft or slightly hollow, especially around the edges and over the rear seats.

That's air pockets where the foam has crumbled. Once those air pockets are big enough, the fabric drops.

3. A faint stain or mark "blooming" through the fabric

This one catches people out. If you see a faint discoloured patch on the headliner that wasn't there before — particularly over the rear window — it's not always a roof leak. The polyurethane foam degrading underneath releases chemicals that can stain the fabric from the inside.

If the stain is forming and the fabric still feels firm, you've got more time than someone whose roof is also rippling. If both are happening, it's overdue.

4. Sag at the rear window edge

The rear window edge is where headliners almost always start sagging — partly because it's the largest unsupported span, partly because it gets the most direct UV. Walk around to the back of your car and look at the headliner where it meets the top of the rear window from inside.

If there's any droop, even 2–3mm, the fabric has fully separated from the board there. From this point it spreads forward fairly quickly — usually weeks to a few months before you'll see drooping above the back seats.

5. The roof fabric is touching passengers' heads

This is the "I have to do something about this now" stage. Tall passengers in the back can feel the fabric brushing their heads. If you reach up and touch it, you can feel air pockets and crumbled foam through the fabric.

At this point, the headliner is held up only by the door seals and the trim around the rear window. Any sharp brake or speed bump can finish the job — and once it fully drops, you're usually pinning fabric up with thumbtacks or driving with the rear seats down. Not ideal.

Why fixing early actually saves money

The job itself is the same price whether you bring the car in at "rippled" or at "fabric-on-head" — the work is the same. What changes is what you have to do in the meantime:

• Early stage: drive normally, book the job for next week, drop the car in, pick it up the same day. Total disruption: half a day off work.
• Late stage: deal with sag for weeks, possibly attempt a "DIY pin job" that pulls the fabric and damages it, then bring it in. Sometimes the fabric is too damaged to re-use the original board structure cleanly.

The other thing: roof lining failures rarely come alone. By the time the headliner is sagging, the pillar trims are usually faded and pulling away too, and the door card tops near the windows are often ageing in step. Catching the headliner early means doing one job. Catching it late often means three.
