Long story short- home is 12 years old, starting to get warping and cracking. Mostly in garage outside in the dry wall.

Had nothing for like 10 years. Only thing I can think of is I had roof replaced a year ago, so maybe humidity is getting in there now?

I had an architectural engineer come out. He doesn't think there are any structural issues thinks it's weather related from when we had no rain for months.

What do I look up in terms of getting someone that can help prevent further damage / repair?

Thanks

Did they change anything about the venting? Remove roof vents, put ridge vents, remove soffit vents, etc

If so, he may have caused humidity in the attic space. The humidity could lead to warping or “biological growth”. I don’t have the appropriate letters behind my name to call growth anything else.

Call a foundation company. That'd be where I'd start.

Sounds to me like some settling going on due to no rain and the ground shrinking up.

It happens in N.O. a lot and houses show signs of stress cracks especially in my area where there is a lot of heavy clay based soil.

I'd bet there's a good chance once the ground gets good moisture to rehydrate it, some of those cracks will not be as noticeable.

Diagonal cracks in the drywall is most often settlement. Dry conditions cause soil shrinkage and often cracks. They will either close or get worse once the rainy season starts.

Vertical and/or horizontal cracks that run along the drywall seams are usually moisture related. Make sure your landscaping beds are not covering your brick veneer weep holes. Also make sure you have good drainage and/or gutters.

Best of luck

Outside drywall??!! Unless t’s a special drywall rated for outdoor use it will be subject to thermal expansion/contraction and moisture expansion and contraction, both of which occur in south La., especially in recent years and at extreme levels for even this area.

Is it drywall tape peeling or cracking on the ceiling, especially the closer you get to the garage door openers?

Unheated and/or uninsulated garages are notorious for the seams peeling or cracking. IMO it's due to one of two things: 1) Due to the temperature contrasts between the air above vs. the air below the drywall, In the wintertime the back (and front) side of the drywall in an uninsulated garage can form condensation and remoisten the taping compound. Done a few times the compound loses it's stickiness and the tape peels. 2) Drywall cracks can also occur as the compound gets wet and drys causing more shrinkage and hairline cracks on the seams. Vibration from the garage doors can also contribute to the seams cracking over years.

Fixing it by retaping and painting is useless unless you're willing to heat and cool the area like you would in the house. As others have mentioned trying to increase the ventilation might help, but I generally consider it was waste of time and money since it's seems inevitable that it will reoccur. If you can't live with the unsightliness of it, I'd think about covering it with wood / vinyl / metal or something else you like the look of. Drywall really isn't meant for outside /non climate controlled applications.
