Rollup service doors: Rolling service doors need at least 14 inches of overhead clearance. For doors spanning the maximum width of 30 feet, the required hood height is 24 inches. Our Extreme® MicroCoil® Security Grille, designed to save space, requires headroom ranging from 10 1/2 inches to 11 3/4 inches.
Roller Doors
There should be sufficient room or clearance on each side behind the opening to house the support brackets and track guides with good working clearance. In most cases, approximately 400mm of head room is required to accomodate the rolled-up curtain.
So do insulated doors, which are considerably thicker than ones with a regular steel or aluminum curtain. A standard, 7.5-foot, manually operated commercial roll up door needs at least fifteen inches of headroom. If the door has an automatic opener, it will require at least eighteen inches.
A minimum clearance between the underside of the lintel/headroom and the ceiling. This varies with the height of the door. See chart below. Door Height (mm) Minimum Headroom* (mm) 1200 – 2200 430 2200 – 2600 480 2700 – 3300 510 *This clearance must extend for a minimum of 500mm horizontally back from the opening.
Six-foot rollup doors need at least 16 inches of headroom, while a 20-foot stainless-steel door requires 25 inches of vertical headroom. Extreme® 300 Series: Doors in the Extreme® 300 Series can be 6 feet to 20 feet tall, requiring either 15 or 19 inches, depending on whether the door is 6 feet or 20 feet.
Minimum Clearance for Garage Door Installations. You'll want a minimum of 15 inches of overhead clearance for a standard garage door with an electric opener.
The size of the finished doorway before installation is called the rough opening. Measure the opening's height and width in feet and inches to the nearest 1/4 inch. If replacing a rollup door in an existing building, check for any irregularities, like a sloped floor or jambs that are not square.
For insulated roller garage doors the space normally required is 300mm (205mm for a compact door) and 450mm for a single skin steel roller door.
There should be a 2mm or 3mm gap between the door and the frame on both sides and the top. If you do need to cut the door down to size, keep in mind that you need to cut all four sides of the door equally whenever possible to retain an accurate shape or pattern if the door is panelled.
Determine Side Room Space
For the door to be properly secured and for the track to have enough space to be installed, there needs to be at least 3 ¾ inches of room on either side. For double door garages, the middle post between openings needs to be at least 10 inches wide.
Limitations in Design and Customizations
Some roll-up doors may not offer insulation properties, reducing energy efficiency options for customers. These limitations mean that certain architectural styles may not be compatible with roll-up doors, and customization options may be limited.
A well fitted door should have a 2mm gap on either side and at the top. The gap at the bottom will depend on the thickness of your flooring/carpet. Plane the door as required, using an electric plane will help you get an even finish, and sand for a smooth finish.
Coil coating and paint costs are key drivers in the price of your roll up door. Typically paint costs only increase due to the raw materials being utilized in other markets such as batteries and electric cars. Each of these markets utilize the same resins that are part of the ingredients to make paint.
Single roller door sizes are varied from 1200mm(h) x 750mm(w) to 3100mm(h) x 3430mm(w). Double roller door sizes are varied from 2200mm(h) x 3435mm(w) to 3100mm(h) x 5500mm(w). The side room is required to mount the L-shaped supporting brackets as well as the roller curtain guides.
Getting the rough opening size right the first time, will save you from frustration, when installing your doors. Framing rough opening sizes are really quite simple. Just add 2″ to the width of the actual door size. You should add 2-1/2″ to the height of the actual door.
Steel sectional garage doors have wider panels than those of rolling steel doors, and rest parallel to the ceiling when retracted. Like steel roller doors, steel sectional garage door benefits are versatile enough to cater to your unique needs. For instance, you can opt to include windows, insulation or added hardware.
Door openings shall have a minimum clear opening width of 32 inches; however, if the doorway is more than 24 inches deep, then a minimum clearance of 36 inches is required. The clear opening is measured from the face of the door to the stop of the frame while the door is opened to 90 degrees.
There should be a 5" distance between the top of the door and the highest hinge, and 10" from the bottom of the door to the lowest hinge. All hinges in between should be equally spaced from one another. Leave a small gap between the door's frame and the edge of the hinge's leaf.
One critical aspect to emphasize is the gap between the door and the floor, which should be between a half-inch and three-quarters of an inch for optimal functionality.
When deciding on the type of door to fit your garage, it's best to keep in mind that a roller garage door will encroach on around 450mm of headroom, directly above the garage door opening. The motor, or garage door opener, is situated to the side of the door itself.
For ultimate space-saving, you can't go wrong with a roller garage door. The curtain rolls into a neat coil above the opening so there is zero intrusion into your garage space.
For a ballpark idea of the most common type of garage doors (roller, sectional, tilt), expect to pay: $800 - $1,400 for single entry level roller garage door. $1,400 - $3,500 for a single premium roller garage door. $3,500 - $5,000 for a premium double roller garage door.
For doors up to 10' tall the minimum head clearance is 16”. For doors taller than 10' there must be a minimum of 24” of head clearance. It is critical that you note the type of material the door will be mounted to, as this will affect the materials needed to install the door securely and safely.

Roll-up doors are usually seen on storage units and warehouses. An overhead door is a residential panel door that moves overhead your opening on a track when you raise it. Therefore, rather than rolling into a coil, the door moves on a track.
