John Kogel Posted August 1, 2011 Report Share Posted August 1, 2011 What happens when you use OSB scraps to finish the job, and you lay a peice up oriented vertically instead of horizontally? You get a dip in the roof, that you have to go back to and fix, somehow. They saved about $10 on a 1/4 sheet of OSB. Tsk, tsk.

Brandon Whitmore Posted August 1, 2011 Report Share Posted August 1, 2011 I could be wrong but..... I doubt it's so much the orientation as it is the lack of support by a min. 3 supporting members. As far as a repair goes, I would just push the sheathing back into place and nail in some 2x4's run perpendicular to the trusses. Quote Link to comment Share on other sites More sharing options...
John Kogel Posted August 1, 2011 Author Report Share Posted August 1, 2011 I could be wrong but..... I doubt it's so much the orientation as it is the lack of support by a min. 3 supporting members. Well I think it is the orientation, so there. []The majority of the strands are laid up in one direction, and the sheets are stiffer in that direction. Same as plywood has more veneer laid the long way, so that is the only way to lay it up. As far as a repair goes, I would just push the sheathing back into place and nail in some 2x4's run perpendicular to the trusses. I suggested that may be possible, easy fix. But I also warned my client that the shingles may not lay flat when they're done, and that he should check for that. Also, it is not technically correct to drive a bunch of nails into truss members, not that it would matter much. Quote Link to comment Share on other sites More sharing options...
Brimar Posted August 1, 2011 Report Share Posted August 1, 2011 I would agree with John. The OSB is similar to plywood with layered veneers. The orientation of the sheet should be horizontal to the framing. This ties the trusses together and provides for more surface support for the OSB.

Brandon Whitmore Posted August 1, 2011 Report Share Posted August 1, 2011 I would agree with John Well of course you do, you're both Canadians, eh.[:-monkeyd Serious question for you John..... Is it really technically incorrect to install a few framing nails through a top chord of a truss? The APA website shows solid wood blocking as an option..blocking Quote Link to comment Share on other sites More sharing options...

gtblum Posted August 2, 2011 Report Share Posted August 2, 2011 What happens when you use OSB scraps to finish the job It's all scrap. They took the Idea from Armour. It's the Spam of Wood. I'm thinkng more in the way of this is what happens when you use mulch and resin to build a house you expect to still be standing in a hundred years. It's junk. I don't care which way you run it.

gpdewitt Posted August 2, 2011 Report Share Posted August 2, 2011 Builder violated this from Brandon's link: "Each piece must be continuous over at least two spans". As we reduce house design to the absolute minimum, every single nail becomes critical. End result - we'll all be living in tents! Quote Link to comment Share on other sites More sharing options...

gtblum Posted August 3, 2011 Report Share Posted August 3, 2011 I guess it's a matter of what you prefer to build with. Saving a buck is saving a buck. http://www.gp.com/build/pageviewer.aspx ... entid=5111 Quote Link to comment Share on other sites More sharing options...
