Removing a support to make one big garage door

Hello,

I am wanting to remove the middle support between the two garage doors and put one 17' door in its place. The roof above the garage is flat. It currently has 2x12s spanning that width supported by a 2x4 wall consisting of 2-2x4 about one foot wide.

The base of that middle support wall is not bolted to the slab, and is starting to rot out. It isn't even 100% vertical; it's been knocked into the garage a little bit. It isn't currently supporting much weight, if any, with no consequences.

The current span of each garage door is about 8'. The new span would be about 17'6". Can the 2x12s span that or do I need to replace them with something else in order to remove the middle support wall?

Thanks for your help!
Bill

Welcome to the forums.

You are allotted 10mb of storage for your pictures. I added the four pictures from the hosting site to your attachments. You can add more directly...... How-to-insert-pictures.

While you "can" do it, it probably isn't recommended. Just drive around any old neighborhood and look at all the sagging garage doors from people who thought it was okay. Something that could help is to bolt a heavy gauge steel flitch plate to it to help resist deflection. But I doubt the ends of that header extend far enough or have the proper trimmers for such a span.

If you want to do a better job, replace the header with a larger dimension lvl.
