A car backing into a garage door, or rolling forward into it, is one of the more common ways a door gets damaged — and it is easy to underestimate. A door can look only cosmetically dented and still be unsafe to operate, because the same impact that creased a panel can bend a track, pull a roller out of line, or throw the whole door off balance. The important thing in the first few minutes is to resist the urge to test it by hitting the opener.
First: stop using the door
Do not run the opener to see whether it still works. If the door is bent, off its track, or out of balance, the opener pulls against a door that cannot move straight — and that turns a dented panel into mangled track, snapped cables, and more bent panels. If the door is open, leave it open. If it is closed, leave it closed.
Keep people and vehicles out from under the door until it has been looked at. A garage door carries its weight on springs and cables under high tension, and an impact can leave those components loaded in a way that is not obvious from the floor.
What a car strike actually damages
- The panel that took the hit — creased, cracked, or punched in.
- The tracks the rollers run in, which bend or shift on their brackets even from a glancing hit.
- Rollers knocked out of the track, so the door binds or leans.
- The cables, springs, and drums, which can be thrown out of balance or damaged by the sudden load.
- The opener and its rail, if the door was moving or connected when it was hit.
- The framing and the header the track hangs from — the damage you are least likely to see.
What's safe to check, and what isn't
From the floor, with the door left where it is, you can look: is a panel creased or split, is a track visibly bent or pulled away from the wall, is a roller sitting outside its track, does the door hang crooked with one side lower than the other. Photograph what you see — straight on and from the side — because it helps the technician arrive with the right parts.
What is not safe is anything involving the springs, the cables, or the drums they wind onto. Those parts hold enough stored energy to cause serious injury, and a crooked or off-balance door is a sign they may already be loaded wrong. Do not loosen, adjust, or try to re-seat them, and do not try to lift an off-track or jammed door back into place by hand. That is pro work every time.
How it gets fixed, and what moves the price
A tech starts by securing the door and checking whether it is safe before anything else, then works out what is bent, what is cracked, and what is out of balance. A single dented panel on an otherwise sound door can sometimes be swapped on its own. A hit that bent track, took the door off its rollers, or threw the springs and cables out of balance is a larger job, because those systems have to be corrected and re-balanced together for the door to run safely.
What moves the price is how many of those systems were affected, whether a single panel or a full section has to be ordered for your model, and whether the opener or the framing was involved. You see a qualitative range up front, and the technician confirms the price in person after seeing the door — there is no way to price a hidden bent track or a loaded spring accurately from a photo alone.
If a vehicle has hit your garage door, describe what happened on rogerrepair.com — which way the car was moving, what looks damaged, and a photo if you have one — and Roger books one vetted local garage door pro and confirms the appointment. Homeowners pay Roger nothing, and Roger does not add a markup on the pro's price.

Common questions
Can I still use my garage door after a car hit it?+
Not until it has been checked. A door can look only lightly dented and still have a bent track, a roller out of line, or springs and cables thrown out of balance — and running the opener against a door that cannot move straight turns a small repair into a large one. Leave the door where it is, keep people out from under it, and have it looked at before you operate it.
Does a dented panel mean I need a whole new door?+
Often not. A single damaged panel on a door that is otherwise straight and balanced can sometimes be replaced on its own, as long as that section is still made for your model. Whether that is possible depends on the age and make of the door and whether the impact also bent the track or affected the springs and cables, which a pro confirms after seeing it.
The door still opens and closes — is it fine?+
Not necessarily. A door can keep moving while running on a bent track or an unbalanced spring, and doing so wears and damages those parts further every cycle. If the door was hit, have it inspected even if it seems to work, because the damage that matters most — bent track, a loaded spring, a cracked panel section — is often the hardest to see from the floor.
