Here's the argument that plays out in a lot of households: one of you looks at the big steel door on a detached garage, workshop, or home-based shop and says, "That's basically the same as our garage door, just bigger." It's a tempting conclusion because residential sectional doors really do come in oversized widths now, they're made of similar steel, and from the driveway they can look nearly identical to something you'd see on a small commercial building. But "looks the same" and "is the same" are two different things, and treating a high-use commercial-style door like an oversized residential one is how springs get overloaded, openers burn out early, and doors end up stuck half-open during a storm.
