I have laminate flooring throughout my house (over 2000 sq ft of it) and I have notice that in several places it is starting to buckle and it looks like it is rolling up on the seam edges- it is random in several areas- even in the middle of the floor- I clean it with a laminate cleaner and dry it good- any suggestions what could cause this & is it repairable without replacing it all?

There may not be enough expansion space around the perimeter of the rooms or the door jambs were not undercut enough to compensate for the shrinkage and expansion of the flooring and house.

That is assuming the floor itself is not damp. Is this a slab floor?
