The wife wants to replace the two with one 16 overhead garage door.
Modify garage door height taller door in a shorter opening.
This is the additional height your garage door will open.
I had a 2x6 on the flat under the header so i just removed that and cut a half inch off the header.
I removed some siding and and re did the trim on the top of the door and then recovered every thing with aluminum and installed new rubber garage door sill around the opening.
It should be obvious that you don t use twice the thickness for the height since you will not be putting anything on the floor but you have been reminded.
It has the old style carriage doors.
That made my door height two inches taller.
Double car garage doors typically start at 12 feet wide and move.
Add to that distance the length of track that is left once you open your garage door.
The height of the rough opening would be the height of the garage door plus the thickness of whatever you are putting underneath the header in addition to the thickness of the mortar etc.
We had a few contractors in to give us.
Because garage doors are usually sized to snugly fit the dimensions of the garage itself making the door larger usually means making the garage larger.
I have a detached two car garage that is getting up there in years.
The garage is a total of 24 wide by 24 deep.
Turn it only a quarter of a turn.
The garage also needs a new floor and a new roof.
One way to do it would be to get wall extensions for the entire the garage and then cut the roof of the garage off lifting it up to the height you want it.
7 1 from the back end of your horizontal track measure the distance of your high lift conversion.
It is possible to install larger garage doors to give.
Reinstall your track and bearing plate.
Older homes have smaller openings for garage doors making it more difficult to fit modern vehicles in.
I live in northern new jersey.
Step 4 test the opener to see if the door height is now at the desired level.
If you wish for the door opening height to increase you will turn the up or open screw in a clockwise direction.
