Frequently Asked Questions
There are some questions that everyone asks when considering installing fencing or overhead doors. We've endeavoured to provide our potential customers with some quick up front information that they may want to know before coming to us with their needs.
How much headroom do I need?
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.
I do not have the necessary amount of headroom. Is there something I can do?
Yes! Low headroom kits are available from your local garage door dealer or retailer. If your garage doors came with extension springs, the necessary headroom can be reduced to 4-1/2”. Torsion spring systems can be reduced to 4-1/2”. More information for both commercial and residentail doors can be found in the Low Headroom Options file listed in our Installation Manuals.
I do not have standard size door openings. Can you custom size garage doors to fit my needs?
Standard residential door widths are 8', 9', 10', 12', 14', 15', 15'6", 16', and 18'. Some models can be custom ordered in 2" increments (8'2", 8'4", 8'6", etc.). Check with your local dealer or retailer for custom garage doors width/model availability. Standard door heights are from 6' to 8' in 3" increments, except for 7'3". Most residential garage doors are now available in extended heights up to 16'. Check with your local dealer or retailer for custom garage doors extended height/model availability. For commercial garage doors headroom depends on model. Doors can be manufactured in 2” increments from 4’2” to 36’2” in width, and from 4’0” to 26’ High. Check with your local dealer or retailer for custom door width/height availability.
I am constructing a new garage; what size should the rough opening for my garage door be?
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.
