For those that know roof truss stuff...

I am really bearing down now on finishing my garage (over half of the wall space has been insulated, wired, been vapor barriered, and has OSB on it), and now I hit a block. Actually, it's the diagonal support brace from the top of the end roof truss to the middle of the third one in. It runs right down thru were I want to put my scuttle hole to gain attic access.

My question for those that might know is, can I replace that single brace with two totally horizontal braces that span the same distance? Basically, I'll just run a pair of 6' two by fours down the inside. If you look at the third pic, I'll just run the two "new" supports similarly to how I mounted the light up there.

Speaking of lights, I decided to give a preview of what's happening on my ceiling. Enjoy!



In a while, Chet.

Who put the frame up? Do you have access to the truss framing plans? Were they pre-engineered trusses? There is a pretty good chance that support was only installed to hold up the gable end while the rest of the trusses were installed. But I would be very careful of removing anything. Common sense dictates that since it is an "open web" truss, that the space where that support is should be open, but you never know.

I think arrowhead is right, they were probably supporting the gable end wall before the overhang was framed. The gable end wall should now be laterally supported if the overhang members were properly nailed to the adjacent roof truss on the inside and the top plate of the gable end wall. The extra supports you suggesting wouldn't hurt, but if your in doubt checking the drawings should seal the deal

I would have to agree with Arrowhead when he said they may be just temporary stays for installing the trusses.

One way to tell is to look at how permanent the nailing is on both ends.

Seems to me that if they were there to prevent racking in high winds, they would be beefed up at the attaching points.

I can't tell from the pics for sure, but they do look temporary. Not only that, but how much could they help if the bottom is just tied to a flimsy cross-tie?

I always installed those braces in order to keep the trusses plumb while I was setting trusses and the horizontal boards on the bottom chord kept the spacing of the trusses uniform...Always left them in as it was too much trouble to take them out..If you feel the need just move it to another spot so that the brace is out of the way of the scuttle hole..That is a standard truss install that is shown and one would be amazed at how much those diagonal braces contribute to the truss system..

I thought they were just there for initial support, just like the general consensuses seem to agree. I will still add the supports, but now I feel much more sure about removing it. Thanks.


In a while, Chet.

You can remove that brace. It does nothing. Nothing unless they only used a handful of nails in the sheeting boards on the roof. LOL!!! Once the walls and everything was tied together that brace is useless. It was probably a temporary brace put up to support the gable end when building the garage. If you are not confident in removing it and leaving it out, remove it, get up on the roof, and move back and forth and see if you can rock the garage roof. The neighbors might think you are a little loopy, but only you will know that And once you get some ceiling it, it will also help to tie things in tighter. The trusses are engineered trusses, so you know the support is built in.

X bracing

First what state are youin? You can replace the x brace as long as they are no more than 4' apart. I am a building inspector in fla.for past 15 years.Make sure you check with building dept. (if you have inspections) in your state.

I'm in Wisconsin. You're a tad late on the advice, I found out from the actual builder (my neighbor goes to church with him) and he said "It's just a brace for while it was being built, just cut it out if it's in the way.".


Kevin, my neighbors all know I'm loopy. No big news there.....


In a while, Chet.

When I built the addition on my garage a couple of years ago, that brace was REQUIRED in my area. They actually give you directions of the requirements for building with trusses here since the last hurricane came thru.
