Replacing A Garage Door Header From 7 To 8 High

If this is going to be a problem i guess we could lower the height of the opening for the door 6 and use a 7 6 high garage door.

Replacing a garage door header from 7 to 8 high.

Over the years the garage door header has sagged du. Width of garage door opening standard widths are 8 9 10 12 14 16 17 and 18 height of the garage door opening standard residential heights are 7 7 6 8 header the header is ideally a minimum 12 wide micro laminated beam that spans the width of the garage door opening. 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. This is the distance from the garage door opening to the back wall of the garage.

These will help to support the new garage door header. The person doing the takeoff had interpreted my request for an 18 9 garage door header to the least expensive 20 long beam. Does 15 leave enough room for the door tracks and a center mount chain driven electric door opener. A minimum depth of the door s height plus 18 is required for manually operated doors whereas a garage door opener can require the door height plus an additional 3 to 4 for standard 7 or 8 high doors depending on model.

Several garage door people have told me they want 18. This header should be an inch and a half higher than the garage door and 9 inches wider than the door. The beam they have specified now is 3 1 2 x 12 x 18 9. 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.

Push the new header into place.

All of the rough framing has just been completed. Step 2 replace the header.
