We just purchased a double-wide (about 20 years old) on 1 1/2 acres of property and only now found out what the source of the "leaking in the walls" in the far bedroom was. One end of the top of the roof (at least 8 feet) where the two sides of the double-wide are joined is literally broken apart by at least an inch or more. This was clearly patched and hidden (and that's another issue) but I have a question: We are being told by the inspector who originally looked it over (whom was the one that first caught the leaking in the walls, but thought it was a cap sitting crooked, etc.,) that it is 'not unusual for the seam where the two parts of a modular are connected to become disconnected.' He said sometimes modular homes can "break apart" at the top like that by far more than 1 inch; and again, it's common. Is this a statement anyone can qualify for me? How common is it? Anyone have any experience with this? Thanks, I would appreciate any feedback.
