Definition
The header is the structural beam across the top of your garage door opening; headroom is the clear space between the top of the opening and the ceiling. Headroom decides what hardware fits — a standard torsion setup needs roughly 12 inches, while low-headroom kits and wall-mount openers can work with much less. Measuring headroom (plus side room and backroom) is one of the first things Door Serv Pro does on an installation estimate, because it shapes every equipment choice that follows.
