Replacing A Garage Door Header From 7 To 8 High

Does 15 leave enough room for the door tracks and a center mount chain driven electric door opener.

Replacing a garage door header from 7 to 8 high. Over the years the garage door header has sagged du. Several garage door people have told me they want 18. This is the distance from the garage door opening to the back wall of the garage. 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.

Step 2 replace the header. Small garage doors may be made in a single panel that tilts up and back across the garage ceiling. All of the rough framing has just been completed. 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.

If there isn t enough room above the opening this can t be done without raising the roof of the garage. 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. The person doing the takeoff had interpreted my request for an 18 9 garage door header to the least expensive 20 long beam. 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.

These will help to support the new garage door header. 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. The beam they have specified now is 3 1 2 x 12 x 18 9. 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.
