The bottom seal is not parallel with the floor, one side rises first, a roller binds, or the door stops at an angle. You may also see a loose cable on the low side or hear a sharp pop before the door changes position.
What you're seeing
A sectional door must be lifted evenly at both bottom corners. A cable that leaves a drum, a frayed cable, a shifted drum, a broken spring, a damaged roller, or a track obstruction can take one side out of sync. The rigid door sections then rack between two tracks that are no longer carrying equal load.

One raised corner is a visible warning. The level door is the intended result after the cause is corrected; the exterior view cannot identify which cable, track or other part failed.

Do not try to straighten a crooked door with the opener, by pushing one corner, or by loosening track and cable hardware. The door can release from a bind suddenly. Do not stand beneath it or park in its path.
The door is first supported so it cannot fall or rack further. The technician then checks cables, drums, springs, rollers, hinges, track position, and section damage. After the failed parts and alignment are corrected, cable tension is equalized and the door is tested by hand before opener travel is restored.
This is handled by our Off-Track Garage Door Repair service. Check availability for your ZIP and exact service address before scheduling.

A displaced roller is one possible companion to a crooked door. Do not force the wheel into the channel or release an unstable door from its opener.

It can become unstable, especially if a roller leaves the track or one lift cable is no longer supporting its side. Treat a partly open crooked door as an overhead load.
Yes, but a bent track is only one possibility. Cable tension, rollers, drums, hinges, and spring balance all need to be checked before the track is adjusted.
One side may have stopped while the other continued, unloading a cable or forcing a roller and track out of alignment.
A level door is a system result; forcing one corner only hides which side stopped lifting.
These references support the general safety guidance above. Your door and opener model instructions control for model-specific adjustments.
A crooked door or roller outside its track is a stop-use condition. A roller may have left the track because of another fault, so putting it back is not a complete diagnosis.
Record which bottom corner is higher and whether a roller is visibly outside a channel. A photograph from outside the travel area can show the opening and both sides. Do not stand under a hanging section, pull on the low corner or use the opener to force it level.
An installer needs to assess the supporting hardware and track condition along with the roller. Ask what caused the displacement and what will be corrected to avoid leaving that cause unresolved. Neither a new roller nor a straight-looking track alone certifies the system.
Tell the provider if the position prevents access or leaves the garage unsecured. Ask what securing the door involves, then request a written permanent-repair scope. Do not accept a remote statement that it can simply be pushed back into place, and do not try cable reattachment or track bending while waiting.
| Observation or choice | What it changes | What to record |
|---|---|---|
| One corner higher | Door may be unevenly supported | Which side and current opening height |
| Roller outside the channel | Travel is not contained as intended | Location visible from a safe position |
| Bent section or track | Repair may extend beyond a roller | Impact history and photographs |
| Garage cannot be secured | Securing and permanent repair are separate tasks | Access needs and proposed scope |
