So far, so good with our roof. It makes me nervous though wondering if its going to happen again. At first we only noticed moisture in one closet by the bed then in the overhead cabinets above the bed. Since the repair I have notice some warping of the ceiling in front of those cabinets but my husband thinks I'm paranoid which I am! No mildew smell thank goodness.
We have had the trailer in last fall for a roof check and there is always something cracked or a screw hole which needs caulking. I would never buy used after I drive around and see RV's sitting for years in yards and its anyone's guess as to the damage on those.
