Making Garage Door Taller

Older homes have smaller openings for garage doors making it more difficult to fit modern vehicles in.
Making garage door taller. I live in northern new jersey. With this kind of width and height dimension you would need garage of around 12 feet width and 12 feet of height door. The garage also needs a new floor and a new roof. 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.
It has the old style carriage doors. We had a few contractors in to give us. But even with the smaller trailers the dimensions you would need for garage of at least 10 feet width and 10 12 feet height. I have a detached two car garage that is getting up there in years.
The wife wants to replace the two with one 16 overhead garage 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. The garage is a total of 24 wide by 24 deep. Double car garage doors typically start at 12 feet wide and move.
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. Travel trailer also come in smaller sizes and they may need smaller door.
