Sectional, roller or tip-up
Sectional doors are the default for a reason: they lift straight up and run back along the ceiling, so nothing swings out into the driveway and you can park right up against the door. They need headroom above the opening — typically around 300mm for a standard track system, less with a low-headroom kit.
Roller doors coil into a barrel above the opening and need almost no backroom, which makes them the answer for garages with beams, storage racks or a low ceiling running back. Tip-up doors are the single-panel type that swings out and up; they are cheap and simple, but they claim the space in front of the door and they are the type most often replaced during a renovation.
Where headroom is genuinely tight, the honest answer is sometimes a roller door rather than a low-headroom sectional kit, and we will say so at the measuring stage rather than after the door arrives.
Automation, safety and load shedding
A new door should be commissioned with the automation, not have a motor added later as an afterthought. The motor is sized against the finished weight of the door including any glazing or timber, and the travel limits and force settings are set with the door already balanced.
Safety infrared beams across the opening are standard on every installation we do. So is battery backup — in this part of Johannesburg a motor without it means a door you cannot open when the power is out, which is exactly when you want to get a vehicle off the street.
The auto-reverse test is done in front of you: an obstruction placed under the closing door, the door striking it, and the door reversing. If it does not reverse cleanly, it is not finished.
Single, double and two singles
A double opening can take one wide door or two single doors, and the choice is not purely aesthetic. One double door is a single mechanism to maintain and a cleaner opening to drive through. Two singles mean one door can stay working while the other is repaired, and each door is lighter, which is gentler on springs and motors.
Where there is a central pillar you have no choice. Where there is not, the width of the opening and the weight of the finished door usually decide it — beyond about 5 metres, a single door starts asking a lot of its springs and its top section.
