Residential headroom depends on the type of spring system that will be installed with your new garage door. For extension springs, a minimum of 10" is required for your garage doors to operate. Torsion springs require 12". Remember, these amounts are for garage door operation only. If you are installing a garage door opener, additional headroom is required. Check with the opener manufacturer for additional headroom requirements.

Commercial door headroom depends on not only the spring, but the track system that will be installed with your new door. There are many options available to compliment your building. Options such as Follow the Roof, Highlift, Full Vertical track, Spring cycles, Door weights and track thickness can all impact the amount of clearance required. Standard headroom requirements for a door with torsion springs, 2" thick track with a 15" radius require 16". However changes will directly affect the clearance needed. It is always best to have a professional dealer look at the opening to determine the best track application and clearance required. Note: If you are installing a trolley or jackshaft opener, additional headroom or sideroom is required. Check with the opener manufacturer for additional headroom requirements.

Depending on the type of construction, the finished opening should be the same size as the door you wish to purchase. The door fits against the opening from the inside. The rough opening should be finished with an exterior perimeter seal or stop molding to seal out rain and wind. For more information, please refer to the Preparing the Opening file listed on our Installation Manual. Doors mounted to steel jambs are typically ordered 2” wider than the finished opening to allow for side seal application.
