I would definitely write it up. Crooked trusses is not the same as crooked dimensional lumber. You never want someone to throw you under the bus by “your inspector should’ve told you”. The only question is what to recommend… that would depend on what I saw (as a whole), the pics posted alone is not enough.

well said , which was the main reason I have reached out.

As I had written above. It has affected approximately 50% of the south facing trusses.
No rafter sag, cracking within the truss lumber or signs of water penetration.

There is currently no evidence of cracking within or along any portion of the ceiling or support walls (above windows, doors, etc)

It was choosing the correct or best way to write it.

Thanks @srechkin

I wouldn’t write that up. I agree with Scott. I rolled and sheathed a lot of houses. Scott is spot on.

It’s worth mentioning, for those looking to learn, that in general, the metal plate connectors have to be in contact with the wood to be effective. The allowed tolerance gap is 1/32". In the OP’s pic, one can clearly see the separation of the plates. Look at these gap numbers (source: TPI). At mere >3/32 separation your metal plate connector is useless. Do you know what 3/32" is? :thinking: The roof, surely, is not going anywhere until it does.

The Truss Plate Institute (TPI) is the bible for truss design, manufacturing and installation. The TPI book states:

“Trusses shall be set and secured level and plumb, and in correct location. Each truss shall be held in correct alignment until specified permanent bracing is installed.”

With the truss that far out of alignment there should have been scab boards to nail into. Total rookie mistake.

I agree 100%.

And a repair that, regardless of what it is, needs to be drawn up by a Structural Engineer.

No repair required for Pete’s sake. Nothing is going to happen. The 50-year-old guy never installed trusses before and truss spreaders were not out yet. For a stick builder, this was all new to him.
Some of you guys are way out of line trying to find something to write about.

Structural engineers must be busy in that neck of the woods! :smile:

…or, as it was being sheathed.

Can’t agree more Marcel. If the “new” books say it ain’t right, it most be so. Problem with society today. That’s all…

They thought so, too:

That has nothing to do with what the OP was asking.
That photo is totally a different issue of installation procedures for long-span trusses or failure under load.

How can one be certain the OP’s roof won’t fail under load? are you okay with MPCs pulling away like shown in OP’s second pic? what if they were missing altogether? What if there were alterations or cuts? just because it stood or is standing, does that mean it will continue to do so? Where does one draw the line or what protocol is one to use to determine if it’s a concern? The trusses in OP’s pic are not merely crooked, the MPCs have pulled away at some of the top cord splices. While you may feel confident the roof may not go anywhere, and it may very well be so, as inspectors, how are we to determine this? We just had a PE above imply they were installed incorrectly. Imagine a client hired a PE to follow up something else HI called out and the PE also mentioned trusses that the HI did not (missed). How would that look? Anyway… I’m just saying, it’s better to CYA in case like this than to be thrown under the bus later. Let someone else okay something that is debatable, especially by HIs and PEs.

I see one mpc slightly pulled away. If noticed multi popping in my attic inspection I would note it. But from what I see in the pictures I wouldn’t kill the deal.
