This is in reply to David. This summer was an awful wet summer. During the construcion of this home the walls were in, the roof was on they did not have any windows in yet. The windows were being installed with in the 2 or 3 days prior to the floor. I guess you could say it was that of a rush job to meet the closing date. Good question you asked, but that would really be backwards to have installed the floor before the roof. Our main concern was that they did not allow the subfloor to dry before installing the real wood.
