Additionally, canopy up and over garage doors are similar in design to retractable doors, but are lighter and do not require as much room to swing open. Unlike retractable garage doors, canopy doors do not retract all the way into the garage, but instead leaves about one-third of the door exposed outside of the house, forming a canopy. This type of single-panelled garage door uses vertical tracks on each side of the door frame to flip open and provide a bit of extra shelter beyond the garage. Canopy up and over garage doors may be a better option for those who prefer manual operation, especially if you are accustomed to keeping cars on the driveway, or are looking for a secure and cost-effective door similar to a retractable.
