The type of damage in your garage door panel
While garage door panel replacement is easy when a single panel is damaged, many people prefer a professional for replacement due to safety concerns. The panels on the exterior of the garage door are susceptible to constant movement, weather and wear & tear over time. While normal wear and tear include scratches, dents, discoloration and minor chips, damage includes distortion or a panel falling off.
If the repair is minor, it is possible to repair the individual panel, given the damage is present within the particular panel. However, if there’s high degree damage such as car dent or major cosmetic damage to multiple panels, the whole garage door panel needs to be replaced.
