Tiles are popping up like a teepee. Doesn’t appear to be moisture around baseboards, this is in a living room/hallway. Will check with moisture meter when I get back from vacation. Tiles have been installed for about 11 or 12 years. Within the past year several of the tiles have come loose but none have popped up in compression.

Any thoughts? Tree root, water leak?

That is known as “tenting”. Caused by no perimeter expansion joints, with the tile having been set too close to the bottom wall plate, or too close to the baseboards, and as the wood expands something has to give, the weak link being the bond between the slab and the tile. It can sound like a gun being fired in some cases.

My house has this same problem. At least once every 2 years, a new spot tents. It was from a crappy install job. Renovations are on deck and the whole floor is coming out. I'm reluctant to put something back down and have this happen again, or just go with a concrete floor and rugs. Still undecided.

Of which, does anybody have any suggestions of a flooring expert in the Northshore/Nola area?

I just had this happen in my home the day after christmas. Most commonly occurs when the tiles are not installed well and a big temperature swing happens.

Once i removed the tiles all 4 had very minimal thinset adhered to the back.
