Storm dents are not a polishing problem; they are a metal-shape problem. In this guide I break down how hail damage is actually repaired, when paintless dent repair is the right move, what pushes a car into traditional bodywork, and what the bill usually looks like in the UK. The goal is to help you protect the paint, avoid overpaying, and choose the route that makes sense for your car.
The best hail repair preserves paint, restores the panel shape, and keeps the bill under control
- Paintless dent repair is the first option when the paint surface is still intact and the dents are shallow.
- Cracked clear coat, sharp creases, or stretched metal usually mean the repair needs filler, repainting, or both.
- UK hail repairs often start in the low hundreds for light damage and can move into the thousands when several panels are affected.
- A fully comprehensive policy usually handles storm damage, but the excess and any exclusions still matter.
- Detailing products can improve the finish around dents, but they do not remove the dent itself.
Read the damage before you choose a repair
The first mistake I see is treating every dent as if it needs the same fix. Hail usually hits the roof, bonnet, boot lid, mirrors, and upper shoulder lines, and the pattern matters more than the dent count. A dozen shallow dents on a flat roof panel can be easier to repair than two sharp hits on a body line.
I always start by checking three things: whether the paint is intact, whether the metal is simply pushed in or actually stretched, and whether the dent sits in a difficult area such as a crease, edge, or panel with poor backside access. Those details decide whether the car is a good candidate for a non-invasive repair or whether it needs conventional bodywork.
- PDR is usually suitable if the dents are shallow, round, and the paint has not cracked.
- Traditional repair is usually needed if the dent has a sharp crease, a broken finish, or obvious stretching.
- Body line dents are harder because the metal is shaped more tightly there, so a small impact can leave a more stubborn mark.
- Glass and trim need separate attention if the storm also chipped the windscreen, cracked a lamp, or damaged seals.
Once you know what the damage looks like, the choice of repair method becomes much clearer and the risk of wasting money drops sharply.
The repair methods that actually work
When hail damage is repairable without repainting, paintless dent repair is usually the cleanest answer. The technician works the metal back to shape from behind the panel, or pulls it from the outside with adhesive tabs when rear access is limited. Done well, it keeps the factory finish intact and avoids the colour-matching problems that come with spraying.
| Method | Best for | What it involves | Main limitation |
|---|---|---|---|
| PDR | Shallow dents with unbroken paint | Rods, tabs, and reflection lighting are used to massage the metal back into shape | Does not suit cracked paint, sharp creases, or heavily stretched metal |
| Glue-pull dent repair | Panels with limited access behind them | Special tabs are glued on and pulled carefully from the outside | Needs a skilled technician; can leave tiny highs and lows if rushed |
| Traditional body repair | Deep dents, broken paint, or badly stretched areas | Filler, sanding, primer, repainting, and often blending into nearby panels | More labour, more cost, and the original factory finish is no longer preserved |
| Glass and trim replacement | Cracked windscreen, damaged lights, broken seals, or clipped mouldings | Separate parts are repaired or replaced alongside the panel work | Usually quoted separately from the body repair |
The PDR process is more precise than most owners expect. A good technician maps the dents under reflected light, works in tiny increments, and keeps checking the panel from different angles. The last stage matters just as much as the first: high spots are knocked down, the surface is rechecked, and the finish is judged under a light board rather than in flat daylight.
If the paint is already damaged, the repair changes completely. At that point the goal is no longer just to remove the dent; it is to rebuild the surface so the panel looks uniform again. That is why the next question is always the same: what will this cost in the UK?
What hail repair usually costs in the UK
There is no honest one-price answer because hail damage varies so much, but the broad UK pattern is easy to see. RAC notes that small dents and scratches can cost a few hundred pounds, while bigger body repairs can run into the thousands. Hail repair usually sits somewhere in that range depending on how many panels are hit and whether the paint survives.
| Damage level | Typical UK cost | Usual approach |
|---|---|---|
| Light hail | About £90 to £250 per panel, or a few hundred pounds overall | PDR on one or two panels |
| Moderate hail | Roughly £500 to £1,500 | Multiple PDR panels, some trim removal, possibly glass or lamp work |
| Severe hail | About £1,500 to £3,000+ | Traditional repair, repainting, panel replacement, and possible glass replacement |
The final number is driven by a handful of practical factors: panel count, dent depth, whether the roof lining has to come down, aluminium versus steel, body-line damage, and whether glass or trim was hit. Aluminium panels and panoramic roofs often push the price up because the work is slower and access is harder.
Insurance changes the calculation. On a fully comprehensive policy, storm damage is usually the part that gets covered, and Admiral points drivers in that direction for hail and storm claims. Even then, the excess still applies, so if the repair quote is close to your excess, paying privately can make more sense. For leased and PCP cars, I would also factor in end-of-term deductions, because visible hail dents rarely help when the vehicle goes back.
Once the quote gets large, the temptation is to reach for a DIY kit. That is usually where the damage gets worse, not better.
Why most DIY hail fixes disappoint
I am cautious about DIY hail repair because the common tricks are inconsistent at best. Suction cups can sometimes improve a very shallow dent on a simple panel, but they rarely solve real hail damage on a roof or bonnet. Hot water, hairdryers, heat guns, and the old heat-and-cold trick are even riskier, because they can stress the paint, soften trim, or distort nearby plastic parts without actually restoring the panel shape.
Detailing products have their place, but they do not remove dents. Polish, wax, and sealant can make the surrounding paint look better, which sometimes makes the dents appear even more obvious because the reflection is cleaner. If you want the car to look presentable before a repair, focus on safe prep, not force.
- Wash the car gently so loose grit does not get dragged across the paint.
- Photograph the damage in daylight and under side lighting for insurance or quote comparisons.
- Leave the dent alone if the paint is cracked, because pressing on it can open the finish further.
- Cover the car if more hail is expected, but avoid tight covers that rub the panel when the wind moves them.
- Use DIY tools only for very minor cosmetic dings, and not on body lines, roof panels, or repainted areas.
In practice, the best use of your time is not trying to “pop” the dent back out. It is getting the damage documented, cleaned, and assessed properly so the repairer has a clear starting point.
How to choose a shop that will not make the damage worse
A good repair shop should be able to explain why one panel is a PDR job and another needs paint. If they cannot clearly tell you how they will access the back of the panel, what they will do about hidden trim, or how they will check the finish afterwards, I would be careful. Hail work is detail-heavy, and shortcuts show up fast under bright inspection lights.
These are the questions I would ask before booking:
- Will you use paintless dent repair first, and only move to paint if the panel really needs it?
- Do you remove the headliner, trim, or light units if that is the only way to reach the roof dents properly?
- Will you inspect the repair under a reflection board or LED light before handing the car back?
- Can you separate hail damage from pre-existing dents for an insurer or lease inspection?
- Do you have experience with aluminium panels, panoramic roofs, and vehicles with multiple dented sections?
- What warranty do you give on paint, blending, and the repaired surface?
There is a simple rule here: the better the shop can explain the process, the less likely it is to hide a poor repair behind a polish. That matters because a clean finish is only useful if the panel is actually straight underneath.
The first 48 hours after a hailstorm matter more than most people think
If I had to deal with hail damage today, I would do the same few things in the same order. First, I would check for cracked glass, leaks, and loose trim. Then I would wash the car, photograph every affected panel, and get one PDR quote and one traditional body shop quote if the damage looked more than light. That gives you a real comparison instead of a guess.
- Check the windscreen and roof glass first, because glass damage can turn a cosmetic repair into a safety issue.
- Document everything before repairs start, especially if you may need to claim on insurance.
- Get quotes that separate PDR, paintwork, and glass so you can see where the money is going.
- Confirm your excess before you claim, because a small repair often does not justify an insurance file.
- Keep the repair paperwork, since it helps with resale, lease return, and any later dispute about pre-existing damage.
The cleanest outcome is usually a PDR-first approach: preserve the factory paint whenever possible, switch to bodywork only when the dent or the coating forces it, and make the insurance decision on the numbers rather than the panic of the storm. If you then finish with a careful wash and a bright-light inspection, you will know whether the repair is genuinely complete or just looks good from a distance.
