I would say water infiltration is the most common construction defect that any lawyer would handle, and that’s essentially water intrusion from an underlying construction defect.  For example, improper window instillation, improper door instillation, lack of flashing.  I see that a lot.  Flashing is interesting because flashing is what’s supposed to be where two dissimilar materials meet; for example, a roof and a wall, a window and siding.

That’s an area where water can enter, and so you’re supposed to have flashing there to divert water away.  If it’s missing, you obviously have a problem.  We see that quite frequently.
