Re: Drywall damage


Wow, that is a lot of force.

I watched one video where the suggestion was made: Attach a rigid 90* angled type material to only the wall stud at the upper inside corner of the wall, do not fasten at the ceiling. Drywall. However, fasten the ceiling wallboard some distance out from that inside corner (as you previously mentioned). Now when the truss system flexes upward that angled rigid material would hold the perimeter of the ceiling wallboard down. The ceiling wallboard would flex rather than cracking at the inside corner.

Crazy stuff.

I suspect it might have something to do with the crown in the wood built in the truss. There has to be some cause that is different only in some houses.

Re: Drywall damage


Not to derail the thread, sorry OP....

The upper part of the truss gets cold and contracts more than the lower horizontal that is in direct contact with the heated finished interior surface, the ceiling wallboard/plaster. Is it that the horizontal piece expands and pushes upward, or, is the upper parts of the truss system contracting and pulling the horizontal upward? Or a combination of both?

Sure so why only some house that are the same with the same trusses?

Re: Drywall damage


So I guess I have the trusses lift effect. I guess I will have to use crown molding to hide the flaws like I did with my other bed room.

Sorry, we kind of took over the thread with that discussion.

You don't have truss lift with a flat roof, you have something else going on.


When you removed the drywall did you find wet or damp insulation?

Re: Drywall damage


Before I did the rebhab I think some rooms had roof leak issue thatís why I redo the whole roof. The other picture I show on the ceiling without drywall also had water leak due to my fault for drilling house on the roof to put up satellite dish for directv but has been fixed already. I exam all those lift tape before and there is no sign of being wet.

But if you had a leak, was that before the drywall problem showed up?

Were the cavities full if insulation?



I am hearing things like flat roofs should never be vented and spared foam is the why to go and foam is impervious to air and water.



But wood expands and contracts and breaks the seal of the foam to the wood and a leak will find a way thru. If you have leak waiting for things to dry out takes forever or you have to rip it all out.

People have been successfully venting them for years but usually they have 2x4 strapping above the joists to help with air flow.
With a system like yours you would need a 1 1/2" space above the insulation and holes at both ends of every bay to allow air in and out.

Any way that you do it it is most important that house air does not get thru or past the ceiling.



All the samples you see for this have the strapping going the other way under the sheeting.

Re: Drywall damage


So does anyone know what is the cause for this damage? Itís only my 2nd floor that is like this. No issue on the first floor.

Re: Drywall damage


It may cause because of moisture, wood movement or leaks. You can apply drywall compound and re-tape the joint cracks. If still it is not working, call any local maintenance company to repair it.
