How to add height to garage door opening.
2 a double door.
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.
For a shed the best size for installing a garage door is 8 x 14 feet.
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.
Pull a measurement from the floor of your space to the ceiling next to the door opening.
This lumber will be used to attach your garage door track and a portion of your assembly.
Double car garage doors typically start at 12 feet wide and move.
As for the height it is 7 or 8 feet.
If you have an rv the door can go up to 10 feet.
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.
Cut two 2 x 6 pieces of lumber and attach to the face of the wall running from the edge of your garage door jambs to the ceiling of your garage.
Then the garage door would be 6 x 6 6.
