We had a few contractors in to give us.

Modify garage door height taller door in a shorter opening.

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. Older homes have smaller openings for garage doors making it more difficult to fit modern vehicles in. The garage also needs a new floor and a new roof. Reinstall your track and bearing plate.

I had a 2x6 on the flat under the header so i just removed that and cut a half inch off the header. Standard single car garage door widths start at 8 feet for single car garages and move up in 12 inch increments to 10 feet wide. Double car garage doors typically start at 12 feet wide and move. 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.

7 1 from the back end of your horizontal track measure the distance of your high lift conversion. 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. The garage is a total of 24 wide by 24 deep. Step 4 test the opener to see if the door height is now at the desired level.

Cut two new trimmers to the height of the new door with a circular saw. It has the old style carriage doors. If you wish for the door opening height to increase you will turn the up or open screw in a clockwise direction. This is the additional height your garage door will open.

Add to that distance the length of track that is left once you open your garage door. Turn it only a quarter of a turn. It is possible to install larger garage doors to give. 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.

That made my door height two inches taller. 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. Add an extra 1 1 2 inches to each trimmer to allow space for the jamb a gap under the door and some wiggle room.
