Our both bald cypress tree has problem

They start pop "knees" last year and then roots come up above the ground,
now one
tree roots are reaching our house, and the other one crossing to next house
where they seems to have excess watering problem. I don't think our soil is
wet (just enough for the lawn). The only thing I would blame is the clay
soil.

These trees were planted when the house was build. I guess this trees are
around 10 years old. I need the advice on these tree. Please email to j b i
