Why Gaps Appear Between Garage Door Panels
Sectional garage doors are built from multiple panels joined by hinges that allow the door to bend as it travels along the curved section of track. Over time, those hinges wear, screws loosen, and the panels can shift slightly out of their original position. This is one of the more common reasons gaps show up between panels rather than the panels themselves being damaged.
A gap can also form if one section of the track has bent or pulled away from the wall, changing the angle at which the panels sit against each other. Weather exposure, repeated heavy use, and age all play a role in how quickly this kind of wear develops on a residential garage door.
Common Causes of Panel Gaps
A few mechanical issues tend to show up again and again when panels don't sit flush against each other.
Hinges connect each panel and allow the door to flex on the curved track section; when they wear or the screws loosen, panels can pull apart slightly at the seams.
A track that has bent, shifted, or pulled away from the wall changes the angle the door travels at, which can leave uneven spacing between sections.
Rollers that are cracked, flat-spotted, or off their track can cause the door to sit unevenly, creating gaps as it moves up and down.
An impact from a vehicle, storm debris, or general wear can warp a single panel enough that it no longer lines up cleanly with the sections next to it.
Bolts, brackets, and fasteners that loosen gradually over years of use can let panels shift out of their tight, flush fit.
What to Do When You Notice Gaps
The right next step depends on how large the gap is and whether the door still operates smoothly.
Small, Cosmetic Gap
If the gap is minor and the door still opens and closes smoothly without noise or resistance, a visual inspection and tightening of visible hardware may be all that's needed.
Gap With Rough Operation
If the door struggles, jerks, or makes noise while moving alongside the gap, hinges, rollers, or track alignment are likely involved and should be looked at before the issue worsens.
Gap After an Impact
If the gap appeared suddenly after a vehicle bump, storm, or other impact, treat it as a priority since a warped panel or bent track can affect the door's balance and safety.
