Would like opinions on the size of header beam needed for a 10′ wide garage door on the gable end of the building. Since there is very little weight on this end, my thoughts are 2- 2×8’s. Yes, the existing doors are 7, this garage was built in the early 80’s, I do not know why they went with the smaller doors. As you can see, the gable end has virtually no load on it. i did not have a continuous header, but in stead two separate headers supported by the studs between the doors. The post are not 20 on center I left the gable end open until I figure out garage door situation. But I thought the door only needed a foot of overhead room.
We’ve all seen 16′ 2 x 12 garage door headers sag, even in a gable wall let alone in a load bearing situation. As such the wind loads (C&C) on the gable end will be felt by the garage door header and sizing of the header may be affected by this increased biaxial loading situation D + (.

I built a 3 car garage some years ago with one 16′ door and one 8′ door. If it is on the gable end of the garage it generally wouldn’t require a header. Dave is spot on. are the doors in the gable end wall of the garage, or are they in the side wall? if it is in the gable end wall, you probably are not load bearing, and so the header won’t be too huge. Are the doors in the gable end wall of the garage, or are they in the side wall? if it is in the gable end wall, you probably are not load bearing, and so the header won’t be too huge. JC also insisted on installing a garage header composed of 5, 20 ft. long 2x10s. This beam would span a 16 foot garage door opening; which was not a load bearing wall! I and another friend persuaded our friend not to let JC install such a massive header. He informs my friend that he will build the 2 gable end walls from scratch with 2×4 lumber; complete with the 2×4 lookouts and barge rafters.
Garage Door Framing
I remember doing one garage door where I had nothing but a gable truss on top of it. You can frame the header on a gable end it doesnt need any beam. My house originally had two 8′ garage doors with a 1′ center post, but i would like to put in a single 17′ door instead. Is the garage door on the gable end?..or am I confused? The top plate above the garage door header may take two sections. So splice them at a cripple stud above the header or above a wall stud. Gable end roof trusses look like a triangle with evenly spaced vertical studs. The header above garage doors can be sistered and and there is a beam missing above shed door.
