truss install

[astidham]

can Trusses be installed before i sheath the exterior side walls with plywood?
my trusses will be delivered Monday and we have chances of rain.
I don't want my sheathing to swell

I would ask the truss company as they probably have experience with this. I would think that if you have temporary angle braces nailed off to hold the walls square that you should be fine.

I think if I were in your situation that I would at least put the sheeting on the corners to prevent racking and then come back and fill in the rest after the truss's

My 2 cents;  I have challenged Murphy's Law enough times (and lost) that I would definitely sheet first.  One rule I keep in mind with any building project is "DON'T RUSH!"  Going slower now is way more time effecient that starting over after your project falls down.  Success comes from making good decisions.  Good decisions comes from experience.  Experience comes from bad decisions.

  You'd have to brace heavily and the time spent adequately bracing should have been spent sheathing the walls .


  You need to plumb and line before hand either way , so I'd say  plumb the corners , sheath the walls  , pull your strings corner to corner , straighten and  brace your walls then set the trusses.

  I'd also wonder why you didn't sheath the walls while they where laying down on the deck it's way easier that way , faster , and better / easier.

  But then that's not your question is it!

Peg thank you for your input, I didn't sheath on the deck because I don't want it rained on.
I want to wrap it as soon as its sheathed

  Wall sheathing , generally , does not have a issue with getting rained on , even a lot of rain seldom will do it much harm. the deck is what gets hammered by standing water.  Roof sheathing , if it's plywood , will sometime blow after a bit of rain, generally just the top layer of ply will swell and pop up. A straight claw hammer drug over the raised ply generally flattens out that issue.

But wall sheathing applied and the walls stood up , not much of a issue with the ply or OSB getting ruined.

Thank You Peg, I didn't know that.

So did you set your trusses yet?

Have you plumbed and lined your walls? Braced them etc?

You do know that even IF your walls are sheathed you still need to / should add bracing to the walls right?

 

Not the best photo but you can see the bracing inside and they stay in place until the roof sheathing is on and nailed off.


Good luck with your project.
