Roller, sectional or something else
The opening and the ceiling often make the choice for you. A roller door winds into a drum above the opening and leaves the ceiling clear, while a sectional door's panels run straight up and then back along tracks under the ceiling.
That track needs depth inside the garage. B&D's sectional door guide recommends 3374mm of backroom for its doors up to 2400mm high when one of its ceiling-mounted openers is fitted. Steel-Line's brochure says its sectional doors are made at least 25mm wider than the opening on each side, and a low headroom rear mount can work with 150mm above it.
If the garage is short on both, B&D offers its Flex-A-Door as a replacement for an old tilt door: a roller curtain on a curved track that sits behind the opening, so the car can park right up against it.
Wind ratings on a Gold Coast home
With the Gold Coast in Wind Region B on the 2011 map, a house here falls in the non-cyclonic part of the scale. Steel-Line's wind rated door brochure explains it: N1 to N6 for Regions A and B, C1 to C4 for the cyclonic regions, and a higher number means a stronger design wind.
Steel-Line also tells homeowners to check the home's own wind load requirements with the local council. NCC 2025 adds a Region B2 to the garage door clause, and Queensland adopts it on 1 May 2027, so a door bought for a new build should match the classification on the approved plans.
Licence, insurance and the motor
Ask early whether the job will be valued over the $3,300 QBCC licence threshold. Above it, Queensland needs the contractor to hold a QBCC licence, and QBCC lists replacing doors among the residential work that needs home warranty insurance before anything starts.
If the new door comes with a motor, look for a power point on the ceiling near where it will sit. In Queensland a motor plugged into an existing point is not electrical work. Anything new is, and the licensed electrical contractor who connects it must give you a certificate of testing and compliance afterwards.
Installing around the Gold Coast
Beachfront streets
Steel-Line will not cover a door installed within 800 metres of the sea, so on a street that close, ask which maker's warranty still applies before you choose.
Hinterland blocks
CSIRO says homes and garages rated BAL-12.5 or above may need specific measures. B&D says its BAL-Maze sectional system reached BAL-40 in testing, and that it is not made for roller doors.
The northern growth suburbs
Coomera and Upper Coomera were on the list of 60 localities activated for disaster help after the Christmas 2023 storms. A door matched to the house's wind classification is the starting point there.
Have these ready when the door specialist calls
- The width and height of the opening, and the space above it
- Whether you want a roller, sectional or tilt door, or would like advice
- The wind classification from your house plans, if you have them
- Whether there is already a power point on the garage ceiling
- Roughly how far the house is from the beach, for the warranty
What we would do
Ask every quote to name the door's wind rating and the warranty that applies at your address. Two quotes that look alike can differ on both, and on the Gold Coast those are the two details most worth comparing.
