The first thing most homeowners do when they back into the garage door or watch a storm fling a tree limb into it is assume the whole door is ruined. A crumpled, bowed-in panel looks catastrophic, so the instinct is to skip straight to pricing a full replacement. It's tempting because it feels like the safe, thorough choice, and because nobody wants to deal with a mismatched patch job.

Sometimes it genuinely isn't the right call. Here's how to tell the difference.
