2 single doors to one big door

I have a detached 24 x 30 with 2 single doors. There is about 18" between the top of the door and the bottom of the rafters. I want cut out the center column and take the heigth of the door up as far as possible. THere is not a header installed. Will I need one? Any other ideas?

You need at least 12" of head room from the top of the opening to the bottom of the joist, I f you plan to put in an opener you need at least 2 more inches, So you need at least 14" of headroom . Now you can install a door with double low tracks or even with quick turns. Thats if you got less then 12 " of headroom. If your gonna put in a single door I would make it easy and allow yourself the 14" of headroom to the joist. The double low tracks dont run quite as a good as your regular radius tracks.And quick turns on a door are sloppy. Also you will need to have a header installed the entire width of the door. Check with your local codes to see what material they want you to use because there is several ways of doing it .

How wide will the door be? Which way do the roof rafters run?
If you're lucky, the door is on a gable end, meaning there is little load to be transferred to the ground.

I suspect the overriding factors are the width of the new door, and the style of new door.

I do not have possesion of the property yet, so my figures are estimates. THe two single doors are a little more than 8ft wide. I belive the total width is 18-20ft. The rafters run parallel to the doors. I am not shure what gable means. Thanks

If the rafters run parallel to the doors, you shouldn't have any issues with your plan, EXCEPT for "collar beams". Collar beams are the cross-piece that creates the "A" in your rafters. Don't screw with your collar beams.


If any of this doesn't sound right, you need to get on-site advice.
If you have manufactured trusses, you must get on-site advice before you go chopping into them.
