Zibby,

Picture 1: Without looking at the plans? (Is that the install instructions stuck in the rafters?

Picture 2 & 3 Gusset Plate is not correctly centered to support all of the members and support needs reattached. End of rafter not fully supported by truss.

What is with the 2x4s on the flat? I just do not get it.

**Eric Barker** · 12-14-2007, 08:58 AM

Unorthodox, non-professional workmanship. Improper bearing and fastening details.

That should sum it up quite well.

Is that a modular or a manufactured home? Just curious as yo just don't see 2x4's used like that in residental construction.

Scott
This is regular home build by KB.
2x4's I see them often used that way.
I did exactly the same home 2 days ago in different part of town and they use 2x4's the same way.
What surprised me I found very little problems on both homes 2-3 years old $150.000.

KB, says it all.

If your inspecting those, don't let your E&O lapse for sure.

That was a good one Rick!

This is an engineered hip roof truss system. Additional support is not needed. The 2x4's on the flat is on the end hip section where the step down trusses are dropped 1 1/2" for a flat framed truss to compensate for the step down. This is a system designed by engineers for the truss manufacturer and the drawings have to have an engineers stamp for AHJ approval. Having installed such systems, I have found this is a much better way to support the sheathing than to turn it 90 degrees and have the possibility of misaligned joints.

Steve,

I think I know what you're talking about and I have had an engineer say that this can be ok if designed as such. In the attached this was only at the peak sections of the roof. All other areas had the 2x4s vertically. Zibby's pictures seem to involve a much larger area. Is your understanding that the 2x4s can be laid flat throughout the entire roof?

In Eric's picture, to what extent could you substitute clips "or other approved edge support" and still meet the IRC and the APA guidelines?

I see what looks like a clip mid-span at the wider spacing, however, what I think you are asking is about 'end support' rather than 'edge support'.

Am I correct?

The last time I read through the APA stuff, all structural panel 'ends' must land on framing and be attached to framing.
