Truss uplift?

All righty then.

In the past i have seen homes where the gypsum board was installed and finished before the roof tile was loaded onto the roof. Then after normal deflection occurred the gypsum board developed cracking much like shown in your earlier photograph

That's kinda what I was thinking Mark. The engineer thought differently and instead offered that the trusses were improperly engineered and should have been built with a 2x6 bottom chord as opposed to the 2x4 as seen here.

Take a look at some other pics showing the many wall patches that have been done more recently in an attempt to sell this house. This is one of the few times I actually preferred to do an inspection in the evening hours as the play of light from my flashlight really accentuates the recent repairs. And yes Robert, some of the doors in the home did not close properly and were out of square. Let us not forget the horizontal crack in the stucco running along the entire east elevation. So is there movement? Most definitely. But unless the interior non-load bearing wall heaved in the upward direction causing the drywall bulge and cracks noted on my first post, some other forces are at work IMO in the roof framing.

The 2 right photos could be header problems.
Was the opening bowed Use your laser level light.
The king stud may be bowed due to no jack studs.
Single header.
Its an old house so settling could be the issue.
Was it in one corner?
A jack stud missing or the double top plate and cripple studs are missing.
Put your stud finder on the wall and look at what is there.

Sorry for the last post.
Looks like settlement issues by the foundation.
The home is under torsion.
Hard to say without being there. I would call out an architect engineer.
When in doubt call it out!!

Thanks for your insight Robert.

Mr. Redding/
You carry a laser 24" lever of good quality and a Digital level to take accuracy readings?
Not what I use in laser level but I do carry the craftsmen digital level. Priceless
You will see how they help your horizontal and vertical openings.
Foundations and floor span openings.

IR or TI.
I have no use for IF or TI.
The only good cert is Renset.
What shows me heat signatures.
I have 2 good IR temperature sensors.
CE and I forget the second one.
ALSO
CRAFTSMAN®/MD 24'' Digital Level
Item #: 090 392 460 10 $ 80 dollars And you have to be misunderstanding of torsion and flex without http://www.professionalequipment.com...igital-levels/

A couple of good tools and you are on top of your mechanical game.


Good luck brother!!
Someone mentioned a fulcrum point.
It sounds understandable given what I see and have heard.

I don't carry either. Just a Stabila 6-foot bubble level. I don't think it is too useful to tell a client that their floor, wall, etc. is a certain degree out of level (or plumb). I think it paints a clearer picture to say, "in 6 feet, your floor is out of level by 1-1/2 inch" (knowing that comment is in no way making an accurate assessment on what may or may not be happening in the floor). The client seems to understand that easier and can get their heads around it.

I had one just today on the second floor of a home. Took my shoes off to feel floor deflections better (works for me ). I didn't even measure this one, but said in my report "floor noticeably out of level. Root cause unknown. Recommend further evaluation by a licensed contractor." Done.

I tell the client and agent zero.
Its notes for reporting.
I tell them nothing but my client will read the report.
As I talk to my client I explain my observations, not my technique, and make recommendations accordingly.
It would be like trying to explain how your IR works right?
They are tools to assess a degree of assumption.

Drywall ceiling was fastened too close to the wall. With trusses, ends of ceiling panels should not be fastened within 18" of partition walls to prevent uplift from cracking panels.
