A garage door is a large door on a garage that opens either manually or by an electric motor a garage door opener garage doors are frequently large enough to accommodate automobiles and other vehicles. This is the distance from the garage door opening to the back wall of the garage. This header should be an inch and a half higher than the garage door and 9 inches wider than the door. Does 15 leave enough room for the door tracks and a center mount chain driven electric door opener.

Take some 2x4 s and use these to add 3 rows of supporting frames around the sides of the door and just below the header. The span above the door opening is framed with a long header that supports the wall area above the door and this header will need to be raised or rebuilt in order to increase the overall door size. Over the years the garage door header has sagged du. These will help to support the new garage door header.

If there isn t enough room above the opening this can t be done without raising the roof of the garage. Small garage doors may be made in a single panel that tilts up and back across the garage ceiling. Push the new header into place. Several garage door people have told me they want 18.

The beam they have specified now is 3 1 2 x 12 x 18 9. Step 2 replace the header. All of the rough framing has just been completed. On previous projects i have been supplied a glu lam boise makes specifically for garage door headers that was 3 1 2 x 11 1 4 x 18 9.
